Hey guys I need some help I'm using my stock deck and I wanted to use an amp. I got this converter that give my head unit RCA output. My question is which wires do I connect to the head unit would they be the speaker wires? Please help very confuse and instructions suck. Thanks

 

yes you use the speaker wires coming out of your stock deck.

 

are you using the amp for the mids and highs or are you adding some subs? if your adding subs, only use the rear speaker wires, and wire the rear speakers, if you have any, in parallel to the front speakers. This way you will have your bass isolated and your mids/highs will be on the front channel while the bass will be on the rear. the only thing is that you wont be able to fade the mids/highs front to rear.

 

Also, don't wire one set of front or rear channels to the amp AND the speakers. Do what saucycivic says and wire all 4 speakers to the front outputs if you are NOT adding a 4-channel amp and are adding just a sub.

If you plan on doing mids/highs with an amp get a 4-channel amp.
