Hey guys I have a 2007 G35 Coupe.

Im putting in a JVC KW-AVX740, and I have the bose system.
I bought my dashkit, head unit etc, I know with the bose system I need the PAC OEM 1.
I have bought that, I wired everything up to my head unit and the cars harness but im getting no power and the head unit is not turning on.

"I want to keep my stock amp and speakers."
"Just want a aftermarket head unit."

Whats going on? I checked all the wiring, power, grounds...
The only thing I can think of is tapping into the ground, and hooking it up to the chassis of the car. Im not getting any power at all, its not even turning on.
I also looked into my amp wiring also, and that looks fine.

If anyone could help me that would be great.

Thanks Ryan.

 

Have you busted out a multimeter and even checked if you have power on the always-on and switched power supplies?

Did you blow a fuse because you didn't disconnect the battery before hooking things up?

Considering you're the one who hooked it up, saying you "checked it" means exactly nothing in terms of troubleshooting. Posting photos of how your wiring harnesses are connected so we can check it, as well as determining if you blew a fuse (using a multimeter) are the few steps you can do to help us help you. If you don't have a multimeter, find a friend who does, and they can probably get this sorted out for you.

 

Sorry I didn't get into detail.

I've checked all of that, and the battery was unhooked.
I ended up finding was was wrong, it was not getting a good ground.
Ounce I fixed the ground it was 100%

Thanks for helping.
