i hate the stock stereo wiring in the rx, shared grounds suck on speakers.

i found it best to ony use the power and dimmer control wiring in the rx and run proper audio cables to the speakers. i did that when i had a stereo in the rx. it sounded much better than on the stock wiring.

Forget rear speakers... its an RX. I just ran new wire to the doors, put 6x8's in the doors and ran new leads for my deck. Used the cigarette lighter as a switched hot for the power. Problem is my Amps are in the rear mounted to my box, so I got tons of wire running from back to forth.

Yeah..modern decks have bridged output amplifiers allowing them to drive speakers at 22 watts rms per channel (don't believe that 45 watts per channel it is peak output @ 10%+ distortion) because the outputs are bridged these decks will at a minimum sound very tinny and at a maximum destroy the output stage if wired to a common ground speaker system, like our old school subs..

My recommendation is to wire fresh wire to the speaker connectors situated under the carpet by where the door harnesses terminate, usually a pink connector, to the back of the head unit, that way the door harnesses remain intact and you don't have a naked wire to pull through the door gromets..I also recommend drawing power directly from the battery to the head unit with a 15 amp fuse in line, then using the existing switched wire to the units ignition inputs, usually a blue wire with a yellow stripe..

just my two cents..
