OK here's the deal I was talking to Don and he said that I should splice the RCA's onto the factory speaker outs and just plug into the pre-amp off of my headunit. I have 4 preouts on my headunit - and I wanna add subs too. The QUESTION is: how do I do this if I use Don's RCA Splice Method - because all the RCA's will be full...is it ok to tap into the rear signal again?! HELP ME!

EDIT: I need the wiring color guide for the 4th gen maxima PLEASE help!

 

use a line level converter. splice it right behind the head unit, and run an rca cable from it to ur trunk!

 

Hmm anyone have any idea's on how to do this, or another way to make this happen?! I think I am gonna get going on this tonite!

 

u splice into the left and right of the fronts and rears in the second harness that attaches all the speaker wires and attach those to the line output converter and then run rca's from that to the amp

the white grey purple and green wires that are on the smaller adapter are the ones u will splice into

 

your supposed to use a line out converter thats what my friend used with his BOSE and it works perfectly
