I am about to buy a 2003 g35 auto, im wondering if anyone has had any issues with there interior or engine because of an audio upgrade. i plan on putting 2 12in sa12s on a 2000 watt amp, a c&d 540 battery, and 2 runs of 0 gauge welding cable and a high output alt. anyone with a big setup have any problems?

 

uhhh where u gonna fit it?

 

haha in the trunk lol

 

any one else?

 

I just installed my sound system in yesterday,the problem is,how are yo going to fit the 0 gauge wire thr the firewall without drilling a new hole and "insulate" it?
And what are you gonna do for power?for example i only have a 600w with 2 cheap 12 and half volume my idle jumps.
third, where are you gonna hide the 0 gauge inside the car?

 

Just run it through the giant rubber grommet that everything else uses. It's right there with the battery. Cut a small hole in it and seal it up with a regular grommet fitting.

There's room for a couple 0 gauge wires along the bottom of the doors:



With the wire tucked under:

 

im going to be getting a high output alt. thats around 220 amps. wrathernut what kind of power are you running and do you notice anything negative it does to your infiniti?

 

i never went that far since my wire is only a 4,the problem i am running in to is the idle jumping(at volume)i guess need to invest in a Farad.
and just to make sure are you a coupe or a sedan?
edit,never mind you are a sedan,could you please upload a picture of your blue harness from the bose amp,if thats the way your connecting your setup,and not from the LOC unit.
Thanks

 

There should be a thread about that
Otherwise yes your drawing a little bit more power than what the car is designed for
basically the idle jump,but i have not noticed any difference at higher RPM like light dimming or ecu cut out or any jerkyness.
Hope that helps.

 

that doesnt make any sense to me, i have a 99 saturn sl2 with a 1200 watt amp wired to 1 ohm and 0 gauge, my stock alt is 90 amps and i dont have any idle jump in that car. 600 watts is nothing, your alt should be able to handle that

 

yeah ive gone through about 200 pages of audio threads here and have found some good info. mostly people saying that they have alot of rattles, but being in car audio i know i need to sound dampen so thats expected.

 

My Fault,its a 800 Kenwood.It rattles a lot,i can take a video if you want to see
But anyways from what i researched some people say that their idle alternates some say no.
but that what i am experiencing.

 

yeah that would be cool, i always love to see others car audio vids. im going to be putting this in a coupe.

 

ill try to put the video later on today since i am in a coffee shop right now and i dont think people would appreciate my sound
is there anything in particular you would like me to film?
Btw what year is your coupe?

 

the coupe im looking at is an 03 g35 automatic. already has a kenwood excelon double din with navigation installed. its gonna be a squeeze to fit all of it in the trunk but it can be done. and yes, i woofer **** is always nice lol, and just overall how it sounds.
