Hey guys, so I'm pretty sure one of the channels is out in my front mach 460 amp in my 94 cobra. I can only faintly hear music out of the front driver tweeter if I turn the volume to max. Makes me think the wiring is fine. I moved the speaker to the right side and it worked fine so the speaker is ok. I switched the RCA's on my pioneer h/u and that didn't help so it's not the h/u. So like I said, I think it has to be the front amp. My plan is to replace it with another stock amp. Don't have the money to get aftermarket amps/speakers right now. After searching ebay it looks like most of them are for the rear amps. The only front ones specifically said not for mach 460. I tried to figure out the PN but couldn't find anything. Does anyone know what the PN is for the front mach 460 amp? And has anyone replaced it? Is it relatively easy or a pain? Thanks!
