Lightbulb Subwoofer & Amp Installation - TL Wiring Diagram anyone?

I'm looking for a wiring diagram so i can us a line converter. I've gotten the rear deck off but i can't figure out which wires are positive and negative on the rear speakers. I'm also still considering simply using the signal for the stock subwoofer to run the aftermarket sub. Would that be too much power for the converter? Also the signal to the factory sub is already crossed over, i'm thinking i might be better off with the full range signal and using the crossover on the aftermarket amp.

What does everyone think?

Most importantly, does anyone have a wiring diagram for the Acura TL's rear speakers?

Because I've spent quite a while researching this the past few days, I thought I would also provide a handful of links that have helped me get up to this point (seat removal, running power wire from battery, ect)

Remove factory sub. reach hand in hole and grab the two wires. one will be postive the other negative.
Grab your LOC and twist the two positives together. do the same with the negative wires. now connect the positive end of the LOC to the positive wire of the sub. do the same for the negatives.
now connect RCAs to the LOC to amp.


Be sure to disable your rear noise canceling mic as it will cause interference with the sub.

Here are a few pics of my install. I also explain how to wire up the LOC(line output converter) with a picture. I just installed my subs, only a few weeks ago.

Which fuse did everyone use to run their amp's remote wire off of? Everything i've tried so far is keeping the amplifier on while the car is completely off..

Nevermind, we tapped into the fuse that is on in the #32 ACC position.

Bumping a 2-year-old thread for a correction. The last two wires listed and their properties should be switched. SW - Green w/red is positive, yellow w/black is negative.

Bumping again for correction of the correction. The Sub wires are correct as above, not as NWSTL indicates. The service manual shows yellow-black as POS and Light Green-Red as NEG.

Potentially embarrassing NOOB question: the LOC I purchased (below) has +/- input wires for both the left channel and right channel (4 total wires). Do I connect the yellow/black and green/red from the stock harness to the LOC's "left" channel, "right" channel, or other? Sorry to be stoopid!!!

Depending on your amp, you may not need a LOC at all. No idea about the wires....the amp that I purchased I'm just running straight from my stock amp.

I would like to know what is the purpose of the 12v cable and ground that appear in the gray connector of 14 pins.
