So - this just completely spared me!!! First - the cheapest multimeter I found that looked like yours was $30 at Lowes. But it doesn’t matter because your test helped me pinpoint that my remote wire was not receiving proper voltage. Come to find out, my floor trim was pinching the wire (I know, rookie mistake). SO GLAD I found this video - your videos always help me and this time was no different!!!!
Hey Mark love the content🤙 just wondering, I have a 2019 F150 and I’m having issues with my right door speaker volume spiking up intermittently any idea what it could be? Thank you!
I don't know why it was so hard to find info like this. I was looking to see if the OEM amp is supplying signal to my subwoofer but for some reason I wasn't getting voltage right at the terminals on the sub. Finally, I understand now that V squiggly is Voltage AC and that I need to test for VAC instead of VDC. Nice! Thanks for the info all in one video.
Hey mark gotta question I got 2 15 in skar zvx in my 02 tahoe today I got rid of the bench seat and put captain seats in there so I can face the port toward the front of vehicle,i was told the subs wont get back pressure this way and mess them up is this true plz any info would be appreciated
Hey Mark, great video as per usual, I have a weird one for ya, I have an lc7i in my car, it’s connected, full power & signal going inn & coming out, whenever I plug it into an amplifier the amp goes into protection mode & I get no sound, I’m not sure what to do, any advice, maybe a setting on the lc7i I’m unaware of?
I tested the AC of the speaker's channel on my amp and they are stable but with the bridged channel I'm using for my sub it goes up and down (when playing a test tone frequency so it should stay stable). Any idea what can cause this?
Hi nice video but one problem I m facing is my Mono amplifier running fine when I only use MONO amplifier but when I m trying to use 2 amplifiers like one 4 channel amp and one mono amp then my amp work sometime then get off (No protection light on and no heating issue) then after some time it automatically gets on and after sometime again off then again on but when i use mono amp separately it runs all time. can you tell me either proper current is providing to run 2 amplifier or there is issue in amplifier. please waiting for your reply
I just installed a full system to my stock head unit. Now my blinkers are LOUD!! and there is a constant buzz. The lower line is run away from speaker wire. Any ideas what I should check?
what about subs output is strong then fades to where you cant even notice them? As in they hit hard and then hardly hear the subs? I have a new alternator and wires ran to the according places.
Funny, but I have that same D6.1200 and just started having a protection mode issue over the last few days. System was fine for 3 weeks. I’ve narrowed the problem down to my front left door mid-bass (Earthquake SWS6.5X), and here’s where it gets odd... The amp goes I to protection the moment I begin to thread one of the 2 screws that go through my MDF baffle and into the actual door (ground). Two things: 1. Why would this become a problem after weeks of protection-free operation? 2. Why would the basket of the speaker coming in contact with a ground source even cause this?
Love the vids. Keep them up. Quick question. When ever I hook up a fan to the amp to keep it kooler, it cuts off. I've switched wiring , used ground as negative and hooked positive wire directly to the power splitter. Still cuts amp off. Like it's going into protect mode. It's an old skool Rockford 801s amp

I know my ground connection is good metal on metal polished so what is going on here, please help.

So I bought a home system subwoofer, I get power to the unit and I can actually run signal through it into my studio monitors/ and successfully get sound through my studio monitors!!! but my subwoofer is just not firing at all.??? Has no sound. I have put my multimeter up to it and it is reading 3.2 ohms. Its a 4 ohm subwoofer. Can't seem to diagnose it unless that means its a bad woofer. It has a slight ruffle sound when I press it in really hard... any suggestions?
if i turn up the volume to high and my amp getting in protection mode .. so i turn off the head using .. after 5 minutes i can play it again . then got protection mode again .. and you got any issues that would could be??
just a question i bought a cerwin vega 1200w amp thinking yeah this will give me more bass than my 600w sony xplod but when i hooked it all up the bass power was actually a little less than the 600w how can this be when 1200w is supposed to be twice the power i ended up running both amps 1 to each 15 inch sub and works well but just don't get how the 1200w has close to the same as the 600w sony is a good brand i know but i must be missing something here
Any instance where amp would go into protect mode when connecting speakers. It is a Ford Focus St with the sony system. The sub/amp combo works, the outputs from the Sony amp are going into AC-LGD to present load to the amp, but when connecting the speaker leads to the secondary 4 channel amp the amp goes into protect mode. I am simply baffled.
My speaker amp goes into protection mode everytime i turn on my car & i just have to disconnect the remote wire & connect it back & i dont have any problem. Its just when i turn on the car. Would appreciate any help. Its just the speakers amp. Never had that problem with my sub amp
maybe someone can help me, but using a hifonics brutus bg 1300D amp i can listen to music and have plenty of bass, ive noticed if i crank it up some and listen to hit enjoying loud bass for a few minutes ill notice it getting weaker and if i turn down the volume the bass begins to kind of stall, where there is still bass but it has very little and cuts out the lower tones and sounds like its distorting. Ive changed two amps so far and been through 3 head units. 3rd head unit with the second amp is doing the same thing. i went back to my other amp that is a little weaker but it is good. doesnt seem to be having the same problem. could the amp just be dying from over drawing the battery??? this all started when i swapped from my alpine amp (around 750-1000 amp i believe) to the hifonics amp vehicle info: 97 ford ranger stock alternator which does only 95 amps. new battery, all wiring has been redone recently in trying to solve issue (new rcas, removed front speakers off head unit and onto seperate amp, bypassed remote wire to just a switch rather than the radio.) I do know the radio gets pretty hot with the hifonics amp
I just installed a jL audio amp 4 ch and wired it all up and only the left rear speaker plays and it’s quiet. I haven’t touched any of the nobs yet what do I do?

Hello everyone✋ I have problem with amplifier, sometimes work's fine, sometimes don't. I tested everything, and only remote wire shows some problems. Voltage on this wire is approximately 8.5V, but, while I was testing it subwoofer just started working, after turn off and on car, again nothing. Is that low voltage on remote wire my enemy?☺️ Thanks a lot
I need help! My system sounds crap and when I turn it up . It cuts the bass unless I turn it down . I thought it was the amp and I bought a new amp and it’s the same thing! It like goes to protection mode. Can it be my wiring ? When I got it done 4 years ago. It was a beast! I might have a feeling it’s my wires
Definitely could be wiring, but also if the gain is up too high it can throw it into protect as well, but assuming nothing has changed then I'd check wiring too as well as matching your gains and everything to make sure
My new amp is turning on but is making a loud static noise like someone blowing into a microphone on and off.then it will stop but im barely getting any sound out of the sub even when i turn the gain up it hardly makes a difference.but the static sound will comeback then pop and cut out again.i had a switch to turn amp on cuz my deck doesnt have one.not sure if thats the problem.if anyone can help email me

Question: what happen when i accidentally shorted the subwoofer positive to the body of amplifier? Issue of my amp no audio output after that incident.

When my car is in the ACC position, the voltage at my amp is around 12.2 and it runs fine. When I start the car, the voltage is just over 14 and the amp does not work. Why would this be?
Hm, I know my input isn't of any use right now, but a car only ever used the full 12 volts when starting the car, so for your car to be reading 14 is well beyond me, hope you find the answer your looking for!
please please pleasr help. ive ran everything how its supposed to be AND i got a NEW amp but it gets overloaded? im getting 14v thru power check via multimeter and 13v thru remote. idk what to do
Hey can u help me my amp is in protection mode doesn't wanna come out of it Im 100 percent sure there is no shorts or pop fuses the thing is that I running a dual sub setup with an areo port and for shit and giggels I removed 1 sub plug up the other sub hole and ran the sub in parallel and extended the port to see if I can hit the lows better and then it when into protect didn't wanna come out it should I buy another amp or is there a fix also idk if it went below ohm load amp is a hfi1500 on 2 l7 12s if the amp went below 1ohm and went into protect how would I fix it
I removed my sub and then added it back in my car and the sub goes into protection mode. I only removed and rettached the rem gnd and pwr cables. Why could this be?
i have a 1000w rms monoblock running 2 8 inch 450 wrms subs ,my head unit is connected with a separate computer supply playing my speakers ,i have my amp connected with a computer power supply in my room but after a certain volume it goes into protection mode ,could it be because i do not have enough power or is my amp faulty?
First off I'd make sure your psu puts out enough power to power it efficiently. Second, make sure your gains and everything on the Amp are set correctly because if it's too high the Amp will try producing more power than it's capable of doing and cause it to go into protect to protect itself from frying
I am only getting 10V from my battery and remote start wire. But the amp is still turning on and in protect mode. Do you know why it's not at 12V I only have a 500 amp setup for subs. I wouldn't think that require any extra power to be put in my car
hey guys have anyone know how it fix a car amp goes into protection mode when you switch to bass mode when ever you rise the volume up it shut down completely
it is recommended that you never go into bassmode. You can change your levels in the back on the amplifier itself. If you dont get the bass levels you wish from changing the settings on the amp itself then it may be time to just upgrade your system. Whenever you get your car tuned at a professional shop you'll notice they never tough the bass levels on the headunit itself.
So I just got a new punch p400x4 and it just shut off on me when I was driving. I was listening at a respectable volume with no distortion and it just shut off on me. I tried to restart my car and my sub amp turns on just fine but the punch amp refuses to turn on. I tired disconnecting the speakers and still won’t turn on. What could be the issue?
Thanks for the video, a lot of good information . I have a question, I just replaced my old amp for a new Pioneer GM-DX874 4 channel , I have 4 speakers and a sub . I basically connected everything as it was on my old Amp and now my sub sounds like regular speaker , if I rise the volume more than half it turns off and besides now I have a static noise as soon as I turn on the radio not even the car. I checked my wires and everything looks good, can you give me any tip on this ?

I’m thinking my voltage drops are from the Hondas eld/voltage regulator system, it will not get a full voltage load at a stop for example, however, if I turn my headlights on, AC , etc.. and I’m driving, it puts out a higher voltage. Not sure what to do to keep the voltage up
I'm getting 10v from the power wire and 11 from the remote start.. what should my next step be?
Hi there. I have a dual xpr520 that cuts out on and off
All wiring is correct
Someday it doesn't shut off at all
And somedays it won't turn on. What can I try?
Best video on car audio testing.
Really good video Mark. Can you do a video about wiring crossover, equalizer and amplifier together please?
Perhaps.. Can you elaborate on your question?
@@CarAudioFabrication yeah so I had this friend, he has a system where he had a cross over, an external equalizer and his amp wired to his subs, speakers and headunit and I was curious as how to do it exactly

Guys i spent 2 days trying to set up my godfor saken amp and i could not get it to turn on, but i finally realised that the Remote wire was somehow messed up and no current was getting through, i did it bois, it worka
Good troubleshooting video Mark. I see some ribbers on here. I guess you have to expect haters when you have know it alls who get bored easy!🤣🤣
I thought I blew my amp, so I bought a new one. Turns out it was a lose battery connection. But this is a bigger amp but it goes into protect mode and it doesn’t seem like it’s putting out what it should. I did notice that after the battery cable messed up that one of my subs is making a scratching noise but it still works but not as good as I think it should and I’m just confused
Hi I’m have a problem with my LC-4-800 I set my gain with a SMD DD1 but as I started to turn the volume up on my head unit the amp goes into protect mode help please
I really appreciate your videos, they have helped me considerably with my installation. I have been buying parts from your sponsors instead of Amazon as a show of support. keep up the great content!
thank you!!
So I bought a home system subwoofer, I get power to the unit and I can actually run signal through it into my studio monitors/ and successfully get sound through my studio monitors!!! but my subwoofer is just not firing at all.??? Has no sound. I have put my multimeter up to it and it is reading 3.2 ohms. Its a 4 ohm subwoofer. Can't seem to diagnose it unless that means its a bad woofer. It has a slight ruffle sound when I press it in really hard... any suggestions?
What if everything tested good until I got to my channel's? Any tips how to fix
if i turn up the volume to high and my amp getting in protection mode .. so i turn off the head using .. after 5 minutes i can play it again . then got protection mode again .. and you got any issues that would could be??
just a question i bought a cerwin vega 1200w amp thinking yeah this will give me more bass than my 600w sony xplod but when i hooked it all up the bass power was actually a little less than the 600w how can this be when 1200w is supposed to be twice the power i ended up running both amps 1 to each 15 inch sub and works well but just don't get how the 1200w has close to the same as the 600w sony is a good brand i know but i must be missing something here
Did I miss anything or are these troubleshooting tips helpful for when an amp is in protect mode ?
Any instance where amp would go into protect mode when connecting speakers. It is a Ford Focus St with the sony system. The sub/amp combo works, the outputs from the Sony amp are going into AC-LGD to present load to the amp, but when connecting the speaker leads to the secondary 4 channel amp the amp goes into protect mode. I am simply baffled.
Can you do a video on the speaker in and outputs are overloaded mine are and I’m so confused I’m running a 600$ amp and it’s annoying asf
My speaker amp goes into protection mode everytime i turn on my car & i just have to disconnect the remote wire & connect it back & i dont have any problem. Its just when i turn on the car. Would appreciate any help. Its just the speakers amp. Never had that problem with my sub amp
maybe someone can help me, but using a hifonics brutus bg 1300D amp i can listen to music and have plenty of bass, ive noticed if i crank it up some and listen to hit enjoying loud bass for a few minutes ill notice it getting weaker and if i turn down the volume the bass begins to kind of stall, where there is still bass but it has very little and cuts out the lower tones and sounds like its distorting. Ive changed two amps so far and been through 3 head units. 3rd head unit with the second amp is doing the same thing. i went back to my other amp that is a little weaker but it is good. doesnt seem to be having the same problem. could the amp just be dying from over drawing the battery??? this all started when i swapped from my alpine amp (around 750-1000 amp i believe) to the hifonics amp
vehicle info:
97 ford ranger stock alternator which does only 95 amps. new battery, all wiring has been redone recently in trying to solve issue (new rcas, removed front speakers off head unit and onto seperate amp, bypassed remote wire to just a switch rather than the radio.) I do know the radio gets pretty hot with the hifonics amp
I just installed a jL audio amp 4 ch and wired it all up and only the left rear speaker plays and it’s quiet. I haven’t touched any of the nobs yet what do I do?
So the trun on wire on mine has 3 volts. How would I make it have 12
What if I got only 11.3 volts at the blue wire and over 12 volts at the red wire? It's an after market retro radio and a 200a4 rockford fosgate amplifier. There are 2 speakers in front and 2 rear...no sound. It use to work fine, but has sat for 8 months at least.
Thanks. Always thorough
Looking for advice
I have mono block 1ohm stable
2x 12" dvc subs at 2ohm
Remote ok
Power ok 12v + and - at 13 14vdc
But amp staying in protection mode light stays red
I have turned it of and on disconnected everything and reconnect it all and then also just conected power and remote but (bass knob and rca) not connected and still a redlight how do i fix it?
Congratulations for 400k 🎉♥️
Thanks Mark
My remote start wire is reading .65 vs 12 when I check it’s voltage as suggested around 2 minutes into the video. What does this mean & how can I correct this?
This is just superb, I have been researching "how to test a circuit board for a short" for a while now, and I think this has helped. Ever heard of - Giyathan Bewildering Gratification - (do a google search ) ? It is an awesome exclusive guide for discovering how to repair your electronic items like a wizard minus the headache. Ive heard some great things about it and my buddy got amazing success with it.
What is the amps is working but the power light doesn’t come on. One of the RCA’s had a bend on the end of the pen so we replace them with new RCA cables but now the power light does not come on with the RCA’s plugged in but it does work when we unplug the RCA’s the power light comes on and still works
Hello everyone✋
I have problem with amplifier, sometimes work's fine, sometimes don't. I tested everything, and only remote wire shows some problems. Voltage on this wire is approximately 8.5V, but, while I was testing it subwoofer just started working, after turn off and on car, again nothing.
Is that low voltage on remote wire my enemy?☺️ Thanks a lot
I need help! My system sounds crap and when I turn it up . It cuts the bass unless I turn it down . I thought it was the amp and I bought a new amp and it’s the same thing! It like goes to protection mode. Can it be my wiring ? When I got it done 4 years ago. It was a beast! I might have a feeling it’s my wires
Definitely could be wiring, but also if the gain is up too high it can throw it into protect as well, but assuming nothing has changed then I'd check wiring too as well as matching your gains and everything to make sure
My new amp is turning on but is making a loud static noise like someone blowing into a microphone on and off.then it will stop but im barely getting any sound out of the sub even when i turn the gain up it hardly makes a difference.but the static sound will comeback then pop and cut out again.i had a switch to turn amp on cuz my deck doesnt have one.not sure if thats the problem.if anyone can help email me
I’ve tried all this and still get that stupid protect light on. I have a scar 400w 4-channel amp for my speakers in the car. Idk why it’s doing that now
I have the Topstronggear 1100.1d. I just bought it a week ago and suddenly no sound is coming out and the orange clipping light is solid on. I was only running it at 4 ohms and it never even got hot... what could this be? The owners manual says nothing about indicator lights or support contacts. Go figure.
I checked all my wires my power wire has 12 volts and my ground and postive also have 12v sometimes drops to 2v i have no power going to my speaker wires what can i do
Hi i have a civic 1990 i put a jl audio amp and its a e1200 to a jl audio w3v3it was working for about 10 mins then the power light starts to dim and now no sound from sub? And the amp dims and dims then totally turns of and now it doesnt even turn on, put a different amp in and that lights up green still no sound and the light dimms slowly? Any help anyone? Im assuming poor remote wire?
You makes awesome videos 👍🏽
Have an issue with high pitch wine with my JVC dubble din from RCA output, it doesn't change like alternator wine and is present with car off/key on. It kinda sounds like 1000hz test tone. I have tryed different set of cables and multiple amp grounds
sounds a little like a ground loop.
@@bricore1535 I think I need to find a better ground for the head unit because it's only from the rca out puts.
Question: what happen when i accidentally shorted the subwoofer positive to the body of amplifier? Issue of my amp no audio output after that incident.
I'd check the fuse
My remote wire only reads 11volts. I've been having issues with my bass cutting out when I go above volume 20 on my radio. But then when i lower the volume it takes awhile before bass kicks back in. Any ideas
Your ground switch the spot to something better. Ground off paint and make sure it’s solid.
When my car is in the ACC position, the voltage at my amp is around 12.2 and it runs fine. When I start the car, the voltage is just over 14 and the amp does not work. Why would this be?
Hm, I know my input isn't of any use right now, but a car only ever used the full 12 volts when starting the car, so for your car to be reading 14 is well beyond me, hope you find the answer your looking for!
please please pleasr help. ive ran everything how its supposed to be AND i got a NEW amp but it gets overloaded? im getting 14v thru power check via multimeter and 13v thru remote. idk what to do
There's nothing wrong with having that much voltage.... Its good actually
Hey can u help me my amp is in protection mode doesn't wanna come out of it Im 100 percent sure there is no shorts or pop fuses the thing is that I running a dual sub setup with an areo port and for shit and giggels I removed 1 sub plug up the other sub hole and ran the sub in parallel and extended the port to see if I can hit the lows better and then it when into protect didn't wanna come out it should I buy another amp or is there a fix also idk if it went below ohm load amp is a hfi1500 on 2 l7 12s if the amp went below 1ohm and went into protect how would I fix it
Amp needs repaired
I removed my sub and then added it back in my car and the sub goes into protection mode. I only removed and rettached the rem gnd and pwr cables. Why could this be?
i have a 1000w rms monoblock running 2 8 inch 450 wrms subs ,my head unit is connected with a separate computer supply playing my speakers ,i have my amp connected with a computer power supply in my room but after a certain volume it goes into protection mode ,could it be because i do not have enough power or is my amp faulty?
First off I'd make sure your psu puts out enough power to power it efficiently. Second, make sure your gains and everything on the Amp are set correctly because if it's too high the Amp will try producing more power than it's capable of doing and cause it to go into protect to protect itself from frying
I am only getting 10V from my battery and remote start wire. But the amp is still turning on and in protect mode. Do you know why it's not at 12V
I only have a 500 amp setup for subs. I wouldn't think that require any extra power to be put in my car
hey guys have anyone know how it fix a car amp goes into protection mode when you switch to bass mode when ever you rise the volume up it shut down completely
it is recommended that you never go into bassmode. You can change your levels in the back on the amplifier itself. If you dont get the bass levels you wish from changing the settings on the amp itself then it may be time to just upgrade your system. Whenever you get your car tuned at a professional shop you'll notice they never tough the bass levels on the headunit itself.
my ground was bad
So I just got a new punch p400x4 and it just shut off on me when I was driving. I was listening at a respectable volume with no distortion and it just shut off on me. I tried to restart my car and my sub amp turns on just fine but the punch amp refuses to turn on. I tired disconnecting the speakers and still won’t turn on. What could be the issue?
Ever find out
Can you do a video about amp guts and how everything works, that would be awesome
watch Barevids
Thanks for the video, a lot of good information . I have a question, I just replaced my old amp for a new Pioneer GM-DX874 4 channel , I have 4 speakers and a sub . I basically connected everything as it was on my old Amp and now my sub sounds like regular speaker , if I rise the volume more than half it turns off and besides now I have a static noise as soon as I turn on the radio not even the car. I checked my wires and everything looks good, can you give me any tip on this ?
