Ultimate Electronics will not install aftermarket head unit!
So, I buy an Alpine 9835 and I want it installed in my 04 GT with the Mach460 system. I have the 6CD in Dash head as of now. They spent 3 hours or so messing with it and they came back and said there is no harness that will support my current amplifiers (the stock 460 ones). Either they could not find the amp on wire or whatever. after hooking it all up they only got soun from the tweeters/midrange speakers and nothing else. So I had them box everything up, and I took it home. I'm gonna figure out a way to do it, but if anyone has any ideas for me, I can't stand the 6 Disc changer, and I want this head unit!
