Another reason not to disconnect cables when your system is powered on, in this case the RCA cables. If you disconnect the RCA cables between an amp and head unit when the system is powered up you can blow a protection fuse (which is soldered deep inside the head unit) causing your RCA outputs to sound bad and not work correctly. I highly suggest always powering off the system before messing with the RCAs (you can hold the power button on the head unit instead of killing the car). If you have a head unit that seems to cause alternator whine in your system, this easily could have been the cause.
This issue can be fixed but it involves full disassembly of the head unit and a soldering job.
And just for anyone who may want to know, the original purpose of this RCA pre out fuse had to do with older amplifier models and even some still made. It was common that if the amplifier was not grounded properly, it would instead end up grounding itself through the RCA cables and head unit. Huge hazard if you think about how absolutely tiny the wires inside an RCA cable are. The fuse is meant to blow before a potential fire hazard can take place in the vehicle.
Only learned this not long ago, so I hope it helps save someone from messing up their head unit, especially with some costing $200+. Such an easy mistake to make and it's not very well known.
Love the channel and build series Parker!
Hey brother, good to see u still bumping away and giving great knowledge for new and even older bassheads,
Do a video comparing 2 taramps 8ks vs 3 Korean board 8k for numbers and sound quality difference if there is any. Gain matched vs strapped.
This would make nice content. Sucks Taramps can't be strapped so it'll be more Brazilian vs Korean amps Gain matched
@@BIGJURAY20 you wouldn't want to strap Korean boards anyway I know they allow you to but the phase match will not be correct that's why it's better to gain match them and phase match them
@@justforlaughs8988 plus I was told about 7-8 years ago, by a few amp repair guys, that strapping amplifiers was pretty hard, on the input section of the amp.
Please?
@@Chuck_Sanders you are correct it is very torturous to the drive circuit on the master amplifier
Great to see Parker 👍😎 Glad to hear the low power 🔋 disclaimer 😉 on Gain Matching using the DVC Sub... I was praying for the Hutch lol 😆 I just use a VOM @ the speaker 🔊 output. You are awesome 👍
Glad to see you parker man that hits love it great video and amazing job
Thank you for the video it really helped me out for what I'm about to do. Perfect timing
Good to hear!
Try place the dbmeter about 12inch from the right A pillar and 4 inches up from the bottom of the windshield 😁 Would be nice to see what you hit on " legal " score if you go on a db drag or something 🤩
Awesome work Parker 👍
Thank you!!
Keep doing what you're doing, my man.💯✌🏼
Way to go Parker! A 156 is awesome!
Those things are moving some air. That build must put a smile on your face every time you crank it up. 👍
Great vidja as always Parker
Thank you Mike!
Congratulations on the 156 that's awesome bud. Keep up the great work.
Thank you man!!
very good advice, thanks!
cool video Parker what we use to do back in the day is fire the subs into the box to try fix phasing issues
Great how to... keep up the great work 😁 👍🏼
I was close when I guessed 153.4, that's awesome brother, thanx for the update
Thanks for the info!!!
Your videos are awesome man
I appreciate you!
American Bass for the win! Super sweet build!
Wow amazing method 👏 really learned something and super easy to do!thanks enjoyed bass head class today.And what a nice score,so your setup likes the lows,I got 143db with two 15inches,clamped the amp and got that score on 842rms in my hatch opel corsa
If your box is right, gain is right and you have good stable power. You will easy get 150db.
I got 149db in a opel vectra c with no sound attenuation. ( That car is the biggest shit i build in )
The same subs did 152db in a vw passat.
And it was cheap 15's aswell!
I had 75ah litihum on 5000wrms ish.
@@Morteexx this amp is 3000rms on 1ohm and no extra battery or anything, stock alternator and 0gauge cables and that's that,played on 4ohm because of battery power and I'm happy 😊 for now.
Awesome!! Nice Work!!👍👍👍👍
I appreciate it!
Dude beautiful job on the 156!!!!!
Thank you so much! I’m excited about it
Nice job brother!!!
Thank you!
Learning a lot from your videos. Keep up the good work. Also, you gonna give those CT Sounds subs away? Lol.
Keep up the good shit!!!
Informative video bro...
Wish We would use dash test method as the standard.
Still congrats on that number
Awesome. That shit bumpin
Great job indeed !
I truly am happy for you my boy that's a badass system right there I need to upgrade mine my ground shorted a little bit started cooking the rubber and where it connects to the body of the car but I got to find a new way to get that on there plus you have any advice for me I keep getting a rumble whenever my RPMs hit about two on my car and I drive a standard like literally the RPM needle will hook up to chill and it will have a rumble with it but only at 2000 RPM
Hell yeah man!!!
If you could can you compare the American bass xfl to the American bass hawk also keep up the good work
Keep it up bro 🫡
Bro seeing this I'm starting to finish sick bro I got a decent little system in my Camaro right now but I am thinking on upgrading come tax season I'll have the extra money and I want to put two 12s in my Camaro but they'll have to be in boxes and I think I will have to get two of them to make it work just because the opening isn't very big but the trunk is huge
What does it hit on the dash though? Excellent information for phase matching.
good info..
Please do a video of the DB score with the subs inverted
Try meter in kick and driver door
Open see if it gets louder as that will build most pressure
Congrats bro a 156 is serious with that much cone area at that frequency!
Thank you!!
Darn right! 156.1, good job!
Thank you!!
do u use dsp I think u could get more out your system with a processing equipment and the dsp will have phase control
I would like to know where you got your dB meter from
when you set the low pass all the way up how do you control it from the head uint i have a taramps bass 5k and am haven trouble getting it set just rite also im running two sundown xv'3's in 5.5 cube birch box tuned to 32 Thanks for making this vids
Can I get sum info on what size amp would u recommend for two-12in audio legion maximus subs? I only have a skar 1200.1 for now
That's odd, both of my Taramps Bass 8Ks (2 yrs old) both have phase adjustment knobs as shown on my YT channel Low Hertz High SPL.
I bought them from Taramps store on Amazon. Taramps must've gotten rid of these knobs within the last 2 years.
I’m getting ready to put an American Bass 12 elite in my car. I know most people put them in ported boxes , but has anyone tried a sealed enclosure can’t really find anyone using them in a sealed box.
Parker when you coming to Los Angeles, I'll buy you a drink or something 😆
Hantek 2C42 costs $123 and handheld. People spend a ridiculous amount more for a DD1. Without phase adjustment you cant do anything with phase. Full bridge amps obviously cant strap (they are internally strapped) but instead of strapping amps I would strap coils.
How’s that radio holding up? Thinking about buy it
It’s been good to me! Had it since 2018
You don't need the multimeter. Dual coil sub, one coil to each amp (one in phase and one out of phase) when you hear nothing the phase and gain are matched.
How come one bass 8k is elevated and the other isn't? I strongly suggest adding anti vibration rubber mounts to both amps if not to an amp rack as well to the amps on that rack. Yes Bass line is supposed to handle vibration better, and they do, but at these numbers it's not worth not spending $5 on RUBBER chair feet donuts at the very least. Lmk if you'd like to see how I set mine up as I do same vibration (dBs) with my two 15s using same amps set-up as you.
I definitely agree. I had to replace 2 of mine because I was in a rush and excited to start playing it. When the new ones came in I put amps off box and installed them with rubber. Never had a problem since.
Man I need you to help me set my gains everything sounds easy but I’m somewhat of a newbie
I've always tuned by ear, but I always leave some head room so I don't risk destroying the subs.
💥💥💪💪
Badass score!
Do you leave both of the gains right there? How do you match them when you turn the gains ALL the way up?
I set the gains and then leave them alone. Just control the volume with my bass knob
You should never have a situation where your gain should be turned all the way up.
@@bradysimpson I should've clarified... full OUTPUT not MAX GAIN 😉
@@Chris-B-Bassin In theory, it shouldn't matter where you match them out (at high output or otherwise), as matched is still matched, regardless. I suppose at higher outputs you could do more in the concept of getting it perfectly matched, but when you consider the risk vs reward of doing so at higher power, it likely wouldn't even be worth it to worry about. If your system is putting out anything more than 2k watts, I wouldn't recommend gain matching at anything over 40% of max output, as it becomes more potentially dangerous (to you or your system) than it would be of any benefit.
@@RAW_Reality he got a 156db so obviously it worked lol I just have never set my gain in center and went with it. I didn't see any further adjustments after that. Even the bass knob would just max to the gain setting on amp correct?
This is the first time you knew what you were talking about, thank you! Now do that with xmax and excusion LOL!!!!!!!!!!!!
Do what, with xmax and *excursion?
Nice
You don't need to adjust for phase because they are already set and matched because there a fullbridge circuit
U r wrong bro
@Josip Purgar no I'm correct I know the circuit there's no phase adjustment
10:08 SHOCKED? Even if touching with multimeter?
Hey parker... what do you usually tune your boxes to?
A good "rule of thumb" that I've always followed is 2Hz below what the "Fs" of the subs you're putting in are listed as being.
(*Edit:* I'd really like to believe that your "Thanks Parker" response _wasn't_ some half-cocked attempt at mockery...)
Thanks Parker that's always good to know
Parker your the bass man 🔊
Thank you Ryan!
👍👍
What would be a good amp for a 12" Skar Zvx d2? Right now I have a crescendo symphony sw1 2500,just wanna get something different
Crescendo makes great amps. Idk which amp that is but if it's a mono D then if were me, I'd switch subs. I've owned Skars best subs and they can't compete with Fi, (or Sundown, DC, DB, and maybe a couple others). Or can easily be the most cost effective method is to experiment with building a new custom enclosure. (Assuming electrical is up to par)
Your skar subwoofer is totally fine. People like certain brands, and there is no "best brand" because, it's what works best for you, and what you like, and what fits your budget. Try the Smart 3k from Taramps, as it will help you, to hedge against rise.
@@Chuck_Sanders nothing wrong with my crescendo amp,just wanna try something different on my Zvx. Just looked on Amazon at taramps Smart 3k it's $274, looking at that one and a jp 23 v2(blue). My power supply is a JS alternator(250a),down4sound 0guage ofc wire kit,Xs power 3400d battery under the hood. My voltage usually stays around 14.2-14.3. and the enclosure is built and tuned to spec for the sub. (Birchwood)
@@thomashood8549 I gotcha. I was just thinking it would help you, in getting more power to the sub, as it puts out its power at higher ohm loads, as well at 1 ohm. Your sub is totally fine, where as some people will bash the brand. I don't like to do that, lol. And your electrical sounds very solid for the power. The Crescendo, is a good amplifier. I ran plenty of their amps over the Years,and they are very solid. The JP amps, are very nice..and you wouldnt go wrong there as well.
Watching you put an 8k on each coil made me anxious lol
I think if u had the American bass Xfls u would gain
Yes you are probably right!
Parker take out 1 sub and I really think it will go louder. If it does then take out a 2nd sub ;)
What’s up brotha
What’s up!
@@ParkerTheBasshead just enjoyed your video man that’s all waiting on the next one
Trash that box build a wall to get rid of all that cab air space and it will be even loader then that but also get a real mic place it on a stand in the passenger seat/floor just at the dash facing the mic at the windshield and lets see what it does then.
OK Ooook!! 😆
Why not just strap the amps?
Can’t strap full bridge amps
@@ParkerTheBasshead makes alot of sense lol im not really familiar with taramps
Taramps Áudio Brasil. The best car amplifiers in word. Hig quality construction is Monster enginer cience componentes hard quality tô construction. Make with best in áudio parts for my is Taramps Áudio Brasil. Is uncridible Power and temperature x in hard work.
156👍💪💪🙏
First
💪🏼💪🏼
It's a sine wave not a sound wave .
You are not a professional worker becase u don't have commences. Amplifier fittings. Professional workers they will not fit Amplifier to subwoofer box. But you fixed to subwoofer box mental
You are not professional hater because all you have to attempt to diss on Parker is his amps are on his box? Taramps shown in barevids video can have issues with high vibration. Parker hasn’t had problems, his box is likely the most solid and least vibrating place to mount the amps.
as u can see hes amps are not screwed straight to the box. They have these small rubber rings behind the amps to reduce vibration. Looks like u have issues with eyesight
@@GTILOUD Taramps Bass model can handle the vibration but even so, I have exact same amps but I use anti vibration rubber mounts on both amp rack and amps bcuz I too am hitting these numbers however with ONLY 2 15s street class no wall C-pillar below window line build.
These video are getting harder to watch
Jeezy stop nervous talking with ur hands.
Hi cX
Yo!
i always watched your content, its good stuff, but just because u gave my man @barevids a shoutout, u gets my comment, like and sub!!!
awesome content bro!
Thanks man! And barevids is awesome! I’ve learned so much from him
Bro you need to get a better dmm wth is that walmart $5 ish like really bro you have thousands and thousands of dollars invested not to mention the countless hours working on this and you can't afford a decent dmm really you should have a liumy lm2020 oscilloscope less then $100
