+1 most of your big name stores CC, best buy, and the like, have installers that aren't really trained for factory trouble shooting. they're more geared towards installing a radio or a sat. radio. some of them are good, but like bullitt said, you'll be better off finding a smaller, more custom based shop. or, suck it up and take it to the dealership. (if you wanna spend your next three paychecks)In your car, one amp buried inside the dash below the CD player runs the 4 tweeters and sends the signals to the two rear amps. The two rear amps play the 4 6X8s. As for Circuit City, it has been my experiance they don't hire the best Techs for troubleshooting. Do yourself a favor and find a local stereo shop and have an MECP certified tech look at your car.
If it is just the rear giving you problems, may be the amp itself. The front and rear amp share the same fuse, #19 (I think) under the hood.im having the same problem my rear amps wont turn on ..does anyone know which fuse it is cuz i have a feeling thats what it is ..
The name of your shop is "Best Buy", right? Then why does the shop I manage only charge $50 for the deck install, 20 for the pocket to replace the CD player and 20 for the harness? Sounds like you are $50 HIGHER! Thats why the "Big box" stores are not always the "best" place to get electronics or installation.:2centscheck all your fuses, if they are good then your amps might have gone out or your speakers. Like Bullit2445 said there is also an amp under you cd player you would have to take it out to access it and none of the amps have fuses on them. I work at best but as there lead tech and it cost 17.99 per 1/4 hour to troubleshoot. Best bet is if you were ever thinking of upgrading do it now. we can bypass the mach system. 49.99 to install h/u, 45.99 to bypass amps, 19.99 for dash kit, 19.99 for harness, and 5.00 materials fee.
