Factory amp bypass

[SunnyTk]

ok so i got my aftermarket deck wired in, but the sound quality from the rear speakers are horrible, and i had this problem with my old wd21.

so my idea is to splice the wires that run threw the amp and reconnect them with the wires running to the speakers. (im too lazy to run new wires, and to scared to break anything)

what are the wire colours of the factory amp harness?

Sorry, but I'm new to the Nissan scene and I don't know what vehicle it is you're looking for information about but I can get wiring diagrams with the wire colors for you. If you can let me know what vehicle it is I'll get it for you ASAP. Let me know.
