C6 Corvette Convertible
JL Audio Stereo System
Well, after months of planning and weeks of work, I'm well underway. I'm
going to post this in C6 general and in Audio as I think it will be of
interest in both areas.
As I'm now in a holding stage, while I wait for my subs, I thought I'd take
this opportunity to show a few pictures of the work done so far. I'd like to
take this opportunity to thank a few people, most notably SteveGermany for his
excellent advice and excellent organization of the C6 Audio FAQ's, Shopdog for
his advice, EVIL C5 for the inspiration for the amp rack, scott fx for misc
tips, and others who have contributed to the FAQ's and answered me via threads
and pm's.
The stereo will have the following components:
1. Head unit - Bose Nav
2. Signal - PAC AOEM-GM24...this plugs in to the cable that emerges from the
back of the head unit and converts the signals to RCA cables. Yes, it does
work with the Nav. It provides 4 RCA's - FL, FR, RL and RR. The other thing I
considered was using a JL Cleensweep, but I didn't b/c of the cost and the
cutting / splicing required.
3. Wiring - I ran a 4 gauge power and a 4 gauge ground from the batter to the
rear. I considered using the rear seat bolt for ground, but as the ground has
to return to the battery anyway, I thought I'd help it along and ensure that
it returned 'unscathed'. I have a 60 amp fuse 6 inches from the battery.
4. Speakers:
a - Front - JL XR 650 CSi's - mounted on 1/4 inch plexiglass (pain to work
with, but strong; used a saber saw and a dremmel to cut).
b - Sub - 2 JL 8w3v3's - installed in a custom fiberglass enclosure that
will sit behind the seats (convertible) - this is the only part of the
installation I will not be doing myself.
c - Rear - Eliminated. As much as I would have liked a rear channel, I felt
the benefit of having the subs right behind the seats, and thus not having to
travel throught the top mechanism, overwhelmed the benefit of having a rear
fill. The subs will be where the rear speakers used to be. below.
5. Remote turn on - I got the signal from the fuse box; I used the heated
seat and used the Mini Add-A-Circuit. I'm not sure if I'll stay with this, as
it turns off power when you turn off the car, yet the stereo stays on until
the door is opened. I may try to find a remote turn on to match this.
6.
Amps:
a - Front will be powered by a JL 300/2. I have the front RCA's going right
from the PAC, along the floor in front of the driver's seat, and back along
the driver's side sill. The speakers have a crossover on the amp rack, and the
wires run back along the same path to the doors. Keep in mind the RCA's and
Power/Ground are intentionally on opposite sides of the car to avoid noise.
b - Sub will be powered by a JL 250/1 monoblock, ample for the subs I will
be using (see below).
7.
Amp rack - This part I'm particularly proud of. My father and I constructed
the amp rack out of 1/2" plywood, constructed a cover and covered it with
automobile carpet. The color is not a perfect match, but it looks pretty good
in person. The amp rack is bolted through the floor with a couple of 3"
stainless carriage bolt to help reduce the potential for theft. I had to lift
the car to install the nuts. The amp rack contains the two amps, two
crossovers and power / ground distribution blocks.
