Some people don't like these amps. I personally love the look of them, and they feel very clean to me. Their power ratings are always good to look at too
I love the sound of alpine subs and amps the little sub u showed flexing was nice 1 of my favorite class ab circuits is alpine 3545 model rated for around 250 RMS and does closer to 750 I also love the kicker zr 1,000 and all the older zr models
i need one of those three way switches for my JL1000/1v2. The Mode slope (off/12db/24db) switch is corroded and barely makes connection so that amp only works if you mess with the button perfectly.
Awesome!!! I have my personal 600/1v3 im trying to fix, what were the value of the gate resistors in your case? Mine read 10ohm but im not sure if thats right? Seems low 👀 thanks and nice fix!!!!
My 12" is currently slamming the full phat 125vrms (could take more actually) and it got me thinking, what would be the breakdown voltage of that enamel on the voice coil windings? I'd be devastated if I killed it, not by heat, but just voltage breakdown alone.
What caused my 500/1v2 to melt the 12v connector?(shop installed) Even with melted connector the amp still worked so the shop refused to replace amp. I had trouble trusting it since so it sits in its box. Where can I get a replacement 12v connector and do you think it will be safe to use again?
If a connection comes loose it could cause sparking which can cause a fire or melt connectors, but without seeing a image of it, can't say for sure. You would think a fuse would blow if that was the case, that is if a fuse was installed.
I have a 500\1 slash....I opened up everything seems to be ok but it seems lime a switch is messed up but it only sounds like its working at half power any help????
Hey sam i have a jl 1500/1 its basically new out the box it ran fir 1 hour then niw its giving me a solid red light saying its in thermal shut down i multimeter the pos and. Neg no beeping so the power and output sude i tested ok i tested the thermal sistor even it is ok any ideas what it can be ? I visually see nothing wrong
@@barevids I measured them 3205 chips all look good on multimeter checking continuity I get about the same number and no dead shorts only dead short I'm getting is on a grey transistor with the different color stripes there's 4 and 1 reads dead short u think if I removed that dead short 1 it be ok to power up also nothing gets warm when I power up also the clip lights stays on with no input plugged in or anything plugged into the output
@@barevids I measured across them all seemed normal reading but the silkscreen is totally fine from output mosfets they are like blanks like Jl is hiding what they are
@@barevids output fets look brand spanking new this amps was took out the box played for 1 hour then stopped cause thermal shutdown but amp was not hot barely warm gain on 3 barely in
Installed and sold so many of these... many of these amps are still going strong to this day. Good repair
Such a clean layout of a board this amp has great power being full ridge same power at 1.5 to 4 ohm I think that's the best class d style.
I wish there was someone like you in the states 😢😢

Great vid Sam hope you are well
watching for the ENDING🔊👍🏼👍🏼👍🏼👍🏼
Hi again Sam 0:15 have great one day mate cheers

10r is fine 😁 anything between 4r7 amd 47r will be OK! As long as they're all the same!
@@barevids solid! Going to attempt the repair once the New PS Fets come in, as well as gate resistors. Thanks a bunch 💪🏼
What would you say is a high quality bang for buck modern amp?

I have the slash 1000 stuck with low ohm light on.
Nothing appears to be burned inside.
Please help

What are the green things that look like double a batteries
I have a 300/4 that has some low volume distortion, any chance that amplifier tutorial would provide me the knowldege to repair it myself?
Where can i get new MOSFETs from?
Hi Sam, I have a 500/1v2 it powers on but no action, do you do repairs? Thanks
If you're in the UK, yep

Do you do service for your viewers
hi can you make a video of a class D amplifier running on a center tapped transformer and testing its power output and duty%
Do i have to read voltage ontop of the cap casing where there is a ❌
I have a JL 500/1 slash. It Powers up and plays but doesn't hit as hard anymore. Do you repair for customers and if so how much?
@@traverwilt5600 for UK based clients yes.
Ok. I'm in the US
How much would a rebuild kit cost?
@@traverwilt5600 that's not a thing. It needs diagnosing properly

Spray all the switches with 99% isopropyl alcohol and flick them back and forth many times to clean the contact rails
do you ever sell amps you've repaired
How do I diag a amp that does not power on at all I have give it 12 volts in but nothing turns on what should the first thing I look for be
Do u happen to fix these for people I have a rd1000 got burnt
@@bobnorris6052 yeah but only for UK-based clients
Man i hate the drive ic replacement. That amp and alpine sub i know sounded great even free air.
I been waiting to repair my class d amplifier, is there anyway you think u can give me a estimate to repair it from you
You in the UK?
😊😊

Sounds like output fets, measure across them ☺

I can repair for you if you are in the UK
@@barevids man I’m on Texas !! Wish u where close by … I actually have a collection of the slash series… but thank u sir
How many homs are the resistances of the power source? of 47 or 100
Use 10-47
@@barevids thank you
Weee can I send it to u for a repair on the same amp
Can I send my amp in to get it repaired?
If you're in the UK yes
can you sghare a schematic for this amp?
@@moochinazz I don't have them sorry
Could you slow it down a bit please? Thanks.
First and awesome!
