I am about to enter the G coupe owners club (and I'm ecstatic!) I have a question regarding the bose and non-bose speaker set ups. For the Bose Speaker set up, the amp is in the trunk (is that right?) does this mean that all wiring for the door speakers goes directly to the trunk? and could I, technically, replace the bose amp, and the bose speakers, and use the existing wires? are there any crossovers inline or anything? I know this might be a little different between the 05 and 04 model years, but i'd assume it would be the same in 03 as in 04, and 06 as in 05.

Thanks!

 

all questions...yes.
no inline crossovers....
tap into wire harness in trunk if you are leaving stock HU in....
burn the stock speakers...
use the Bose amp as a planter for your petunias...

use the "search" function for wire diagrams....

So, I would place a new amplifier in the trunk, and just hook up the wires to the new amp... and they would run to the new speakers?! that would make my life so much easier if that were the case!

 

Taosd....do you have nav in your car? If so some of those wires control the navigation voice as well. If you are replacing just the doors, quarters and deck speakers then you will have to replace the amp.

 

No, there is not factory nav in the car. So, I get a 2 or 4 channel amplifier, drop it in where the bose was, cut some wires and reconnect them to the new amp, then replace the door speakers and they will work? (I'm sorry I keep asking this question over and over, but its just sounds too good to be true)

 

It's not as easy as plug and play because you have to pick the correct wires to tap into for the audio signal and to send the amplified signal to the speakers. Look at the sticky threads and they will give you some pointers.

 

if you keep the stock HU ( and not do DD conversion with aftermarket HU), if you replace the amp, you will need LOCs for the aftermarket amp or something like the JL CleanSweep or something comparable.

 

+1 to everything above

Speaker wires will work with aftermarket amp.
Need LOC or Cleansweep to connect Bose HU to aftermarket amp.

 

I'd be getting an aftermarket head unit as well... so... standard RCAs to the trunk, then use the existing wires from the bose amp... I'm pretty surprised that you can just do that... and really happy about it!

 

Yeah that's way easier than running wires through the molex fitting.

 

I didn't use LOCs with my stock Bose HU's in either my coupe or sedan when connecting them to their respective amps.

 

Just spliced RCAs?

 

^ Yes. The Bose is already a low line level signal. If anything, it could use a line driver to boost the signal to between 2 and 5 volts. But it works well with RCAs spliced to the Bose HU output wires.

 

I believe most or all JL amps do not require LOCs. I called JL directly and got it right from the source before I wired it. I also spliced the RCAs
