I had the same problem! I had to use the Amp with one channel (front) disconnected for about 2 months before I found a second hand replacement. Managed to score a bargain and get it for $50 from a wreckers! I still have my old Amp so if anyone figures out how to fix a broken channel please let us know.

As of this writing, I don't think anyone has. The original thread, with a single bad channel shouldn't be to hard to troubleshoot though!

If yours doesn't work at all, these are known to get water damage from the trunk vent failing. Look on the rightside in the trunk under that plastic tray for water damage. Aka traces of rust.

j'ai regarder si il y avait de la rouille et il n'y a rien et vu qu'il fonctionne avec le contact je me dit qu'il a surement un probleme sur le circuit au plus apres contact .car la tension est bonne a l'entree.

Probably a cold solder joint. I would touch up all the capacitor joints just for good measure.

Look for bulging leaking capacitors too. IC's with blisters, bubbles, melting. Obviously check the left right balance and make sure no one jacked with input settings.

j'ai voulu essayer de tester le circuit mais personne n'a le schema c'est un peu embetant.mais je vais essayer de refaire les soudure . Je redemonte l'ampli cet apres midi je vous mettrais des photos

And maybe be so kind as to translate to English going forward?

You have any test equipment like an oscilloscope?

Thank you. I quickly reassembled and cleaned it but still there is a sound when I turn on the ignition but after that nothing more. Sometimes when I am driving it comes on for 2 seconds and then turns off
