Is there a kit made that will wire in aftermarket amps to the factory reciever?

im not quite sure what its called but i have a a small device that i installed that connects to the two wires that go into your speakers and carries that signal into the amp....it costs about 20 bucks and is really easy to install. you can find it at a local electronic or sound store.

Thats a line level converter, I am hoping there is a plug in harness that will linelevel directly off the reciever, I want to run all of my speakers off of my amp's, it's probably wishful thinking but I thought I would ask?

some amps offer speaker level inputs that you can plug into

Yah a 4 or 5 chanel with a speaker level in is your best bet...unforunatly there is no easy way out of wireing with using factory hardware...
