Infinity speakers and amp.
I got the sun, sound and leather package on my 05 and I want to replace the head unit with something that plays mp3's and sirius. I don't want to replace any of the speakers or the amp. Does anybody have a wiring diagram of what the speakers ohm rating is and how the head unit connects to the amp.
I am assuming the speakers are hopefully 4ohm and the head unit connects to the amp via 4 composite cables because it's 4 channels?

you need a wiring harness mad by metra. it is part # 70-7003 ($25). You can call your local Circuit City to see if they have it or you can special order elsewhere. I ordered over the phone from lafayette electronics for $18. pm if you need the info. It has everything you need in order to hook up to the factory amp. no splicing and very quick hook up. trust me on this one. i spent about 2 days doing research. I got a Pioneer head unit (DEH-7700MP) and it really brings out the factory speakers.

Factory w/out amp
Just to add info... I do not have the factory amp and installed the Pioneer DEH-770MP and ipod hookup. Bought it all on ebay for about $300 and had installed for $100. I do not think they used the Metra thingy.

So basically all the speaker outs coming from the deck go into the amp then it goes to the speakers from there instead of using the rca's. Doesn't that cause distortion since aftermarket decks supply power to the speaker wires then that goes to the amp then they are amplified again and sent to the speakers. Or does the infinity deck power the 4 door speakers and then it sends of a low pass signal to the amplifier? I thought the infinity amp powered all the speakers in the car and the deck doesn't power anything?

edit: if you need more technical details, i recommend calling the techs at metra (800.253.TECH ). tell them you have the infinity system on your evo and they'll go from there. they explained everything to me and i'm pretty much a novice. get the harness and you'll understand everything when you pull the factory unit and see all the wires.
