My cousin took out his factory radio, and we are trying to install an aftermarket one, I am at a loss trying to figure out what is speaker wires on this thing! He has 6 speakers, and the only ones i can get to work are the two tweeters up front..? His stereo has a built in amp, so power should not be a problem, yet how come no mids or rear speakers? does anyone know where I can get a wiring diagram on this, or any ideas? thanks if anyone can help!- Gene

Are you bypassing the OEM amp or not ? Where did you tap into for the wires ? If you tapped into the wiring harness at the back of the deck, it will not work because you need to grab the wires at the output of the amplifier going to the speaker's if you wanting to use the aftermarket deck to power OEM speakers using OEM wiring.

The image above is what the amp should look like if you have the system with the amplifier. ------------- Jeff
