Good video. I have the same amp. When ran properly JLs last forever.

Oh man, been down that road with repairs and actual install jobs. A shotty technician is the worst enemy of a good technician.

Do you know the package size for the 470 ohm resistors on the power supply side you were looking at?

Hello, I was wondering if you could provide me on where to get some replacement screws for my JL Audi 500/5 amp? I need to replace the screws for the speakers, remote, and power cables. Thanks

Thanks for this. I have the same issue with my 300/4 V1. I'm pretty sure my gate driver is toast. I get 3 boards to light but not the 4th. I'll be looking over the things mentioned here in this video. Any chance you still work on amps in case I'm unlucky.

I am going to be replacing the IRF540N MOSFETs due to the low ohm light staying on without speakers connected and some distortion in the right rear speaker. Are IRF540N's?PBF's the same as IRF540N's?

[@THEtechknight]

Yes. just lead-free
