I'm upgrading all the in-door speakers, and putting a new amp in my 02 Tl, I have been looking around on the forums and haven't found anything yet. Is there a convenient location in the car where all the stock speaker wires are, or am I gonna get to have fun running all new wire?

 

since there are no rear deck speakers your best bet is to run your own, you could use the rear speakers wires for the fronts with some simple wiring at the deck and then just run rear wires to the rear doors. for the like 7 feet of wire you'll save id say just run all new wire. just pick them up at the deck.
do you have an aftermarket cd player or stock head unit?

 

behind the deck..

 

behind the deck is easyer..

 

I got an aftermarket deck, Pioneer AVH-P7800DVD, I'm gonna be putting in a JL Audio HD600/4 amp and it's a choice between Boston SPZ60's, or RE XXX 6.5 components.

 

if you wanna save some wire just connect your front speaker wires(white and gray) to your rear wires (purple and green) at the deck, then pick it up in the door sill at the b pillar, and run your rear speaker wire directly to the b pillar from the amp. that way your front speakers will have the wires run to the b pillar and all you have to run is 2 lengths (per side) to the b pillar. you'll save a bit of wire, and time.
I'm biased in recommending speakers cuz I'll only recommend what i sell. sooo I have infinity kappa components in my car and they are great. crisp and clean. I run about a 1000 watts to them.

 

Id do it right and just connect line converters behind the HU and run RCA's to the amp, then run quality wire to all the doors from the amp

 

do it once and do it right.
leaves room for expansion and upgrading too.

 

l.o.c's shouldn't be required with the aftermarket head unit, as long as you have front, rear and sub pre outs on the deck.

 

hes got an aftermarket deck, so its equipped with the RCAs already..

and as i stated above, just do what i did in my accord and run all the wiring from the back of the deck.. bundle the wires together and run them all to the back either down the center of the car or under the carpet on the drivers/passengers side..
