Hey guys,

i have a JL500/1 and an Eclipse Aluminum 12" i have a box and everything i just need to know where i need to tap into to get signal for the amp... i've searched everywhere on the forum and haven't been able to find an answer... Please help me thanks in advance for any info... i have a 2003 G35 Coupe with the Bose System.

Just go look in the FYI board. They have the bose and non-bose wireing schematics.

Tap the signal BEFORE the Bose Amp, which is located to the left of the spare tire in that black cover box. You have to remove 3 bolts, and it's there... and run your wires accordingly.

By running before the bose amp, you arent getting that bass rolloff at high volumes correct?

I think you do, I know the SVC works. Miight wabt to set your sensitivity so max volume happens at 17-18 to avoid the possibility

yeah i know that but the links on most of them don't work so i need to know what wire color to tap into like for remote, and the LOC... thanks again

I have done 2 G coupes before. Mine and a friend with after market amps. Pretty easy actually. If u want to use stock head unit then have to jump the wires. As one poster told you before. The stock amp is located next to the leftside of the spare tire. Before jumping the wires, have your new amp ready and need to have the signal translator (or w/e they called it). Because your head unit output is in high frequency, and you don't want to use high frequency into ur low refrequency input unless ur amp have high frequency ready. That thing costs $20. You will figure out when you look at the stock amp wiring. Let me know if you need more info.

i know we have to jump the wires, but i was wondering if anybody know which wires are the low frequency wires that run to the amp (I'm not really good at reading those wiring diagram... i know i'm stupid, but sorry. they just look to confusing) ... thanks for helping though

AFAIK the head unit does NOT output low frequency separate from high frequency. That is done at the amp itself. So what you have is

right front
left front
right rear
left rear

into the amp

and then the front doors, rear arms, subs of the Bose amp. Of course they each have corresponding pos and grounds. Trust the wiring diagrams, they are correct. I used them over a year ago on my coupe...myself.

i appreciate the help guys... sorry if i have been difficult... thanks again info is very useful hoped it helped others also
