Audio Install (Bose)
Hey Everyone,
Im picking up a Pioneer Avic-D3 and i was researching the install and it looks like i need to get an amp that runs 2ohms and a sub. I want to keep the bose speakers so will i need to run the cords from the headunit to the trunk and tap into the bose amp harness or run each speaker to the trunk individually?(i hope not)
Also if anyone has any cheap recommendations for an amp please post them and if there anyone with diy or experience doing this, please help lol

You shouldn't have to get an amp if you're just installing a HU.
Have you read this DIY on the install?

You should be able to buy a wire harness from scosche that the connects to the factory radio harness. So you shouldn't have to run wires all the way back.
If you're just replacing the HU you wont need to buy another amp, just get the wire harness and follow the DIY I posted. Only reason you'd get another amp is to add a sub or do full system not just to switch out HU.

its the bose fiber optic system though, you have to run the wire so you can tap into the harness in the trunk(i think)
and it looks like on the stock headunit and amp work together because of the fiber

Whoops...I guess I was thinking of the other silver coupe member with that headunit..."powa"
But I don't think I've seen him in here in a while....
If you swap out the speakers for non bose...your installation will be much easier. Unfortunately, I'm not too familiar with the fiber optic wiring of bose to help much more.
Search for the aftermarket headunit thread...there should be some good info on there....including an old diy I wrote up for my avic d-3
good luck!

I have isntalled it on another members W203 retaining the bose speakers. fiber optic is only the signal to the amp (remote turn on). you can cut the speaker wires coming out the amp and run back to headunit it will work just fine no need for an amp.
