I've toyed with the idea of doing that before. I don't have a wiring
diagram, but I have a decent understanding of how the whole system fits
together.
My solution is probably ultimately going to be adding a nice 4+1 channel
amp, but there's a lot of other things I want to spend money on before that. :)
Anyway, here's how you should be able to figure it out.
Going into the amp from the head unit should be 9 wires coming from the
receiver. This would be +/- for 4 speakers [match the colors up with what
comes out of the back of the receiver] plus the turn-on lead [same deal for
this]. Likewise, there should be +/- for each of the 4 speakers coming out
of the amp. [match the colors up with what connects to each of the
speakers] In addition, there should be the main power and ground
leads. There may well be an extra wire or two floating in there.
In theory, to bypass the factory amp, you ought to be able to cut off all
of the speaker leads and splice the appropriate ones together (front left +
-> front left +, and so on.. no brainer). You probably want to disconnect
the turn-on lead when you test this as well. There's no reason that I can
think of why it wouldn't work; I just haven't had the time to figure out
all of the colors. Of course, the real bummer is that if it doesn't work,
you now have a bunch of ugly spliced back together wires connecting your amp.
If you do try it, let me know how it works. BTW, what year is your truck?
