Hi, as stated I purchased a 94 c280 with speakers not working for a steal. Everything else is mechanically tight outside of it. I had a local car audioshop look at it and they states that the reason there is no sound coming from my speakers is because the amp is fried. I have two questions. Firstly, I don't believe my system is Bose since I didn't see any branding on any of the speakers but is there a way to make 100% sure that it isnt. Secondly, if my car is indeed not a Bose speaker system, what amplifier should be used. I've searched ebay and all I can find is Bose amps, is there a specific name or model number to the amplifier I should be looking for?
