Hey guys , listen I need some help . I recently had a local radio shop install my Pioneer Premier 940 headunit in place of the factory BOSE . The shop owner and I got into a large fight cause he tore my car apart and it looks like SHEET . Anyways , I'm probably gonna rip everything out and ask for my money back . What I need help w/ is I need to know what I need to use to bypass the factory BOSE amp . What have u guys used to actually wire in the aftermarket headunits . Mine right now has a box called a Peripheral Adapter in between th headunit and the factory harness . The guy says it's there so I don't have to disconnect my factory amp . I have engine noise now and want to do the entire installation myself . What can I use to install this headunit . PLEASE REPLY!!!!!

 

Damn, that sounds bad, where did you go? I don't know how to by pas the bose, but i would assume you can just replace the wiring and just forget the bose amp even exist.

 

I went to Sound Advise in Long Island . I was thinking about just running all new wire for the speakers and power and ground and completely bypassing everything , but wanted to know what u guys used . The service there was horrible and way too overpriced .

 

I would suggest getting a decent aftermarket amp.

 

Thats what I'll do If I do it on my own .

 

The engine noise is probably a poorly grounded component. Go through each component and make sure everything is grounded to the chassis.
