Does anyone have the wiring diagram for the speaker input wires from stock HU to Amp. I'm currently tapping my signal from the speaker output wires after the amp.

I'll be reinstalling everything once I've saved enough money to get an aftermarket receiver. Now it's between: Sony M620, JVC SH77 or SH99, and Panasonic U801.
Damn crappy stock HU is pissing me off.
