Did you make the wiring harness or buy one? Or does it plug directly into your vehicle? or did you just splice the wires?

SOURCE: installing after market stereo

Dave,

You will need to go buy a wiring harness adapter from your local Walmart (usually cheapest there) or Local Electronics place (ie Best Buy). The wire harness that goes out from the radio goes into the Adapter and the adapter plugs into the car harnesses. Also these Adapters come with the wiring diagrams for your vehicle. They typically run 10 - 15 bucks depending on where you get them. Thanks for using FixYa!

Sincerely,

JC

I have a 2003 chevy tahoe Lt the air works in front and with back controls but heat is only working in the front it blows with back controls but puts out no heat what causes this?


Your climate system can only cool or heat but not both. The temperature has a big effect on this. The cooling needs the compressor.

I suggest you have the dealer look at this, you can't get parts for the AMP as GM doesn't sell them to the public just authorized repair shops

I have a 2003 Mazda MPV that has the stereo that you could add a cassette deck or MD to...I do not have either, but there is a button for it. I found a guy on the internet that made a chip that plugs into the back of the radio and has a 3.5mm jack on it that will play when you push the cassette/md button on the radio. It is great....sounds just like one that came from the factory.

My 2004 Grand Am GT Stereo Issue


I had the same problem when I changed out the factory cd player. I finally found the problem was that grand am gt cars have a couple of amplifiers with crossovers in them for the speakers and the after market stereos put out sound that has been slightly amplified already and when you hook up your new stereo to the wiring harness your sending amplified sound from your stereo the the factory amp then to the speakers this sometimes messes with he sound and clarity of the sound. My car is 2002 and the factory amps are located 1 under the glove box and 2 in the trunk behind the carpet on the drivers side. The amp and crossover in the front is to split the signal for the door speaker and the tweeter by the mirror and the amp in the trunk is to split the signal for the two way speaker in the back by the back window witch if they are like my factory speakers have 2 wiring harnesses connected to each speaker. the only way I could get mine to sound good was to run new wires from your stereo directly to the speakers and bypass the factory amps. This may not be the only way to fix this issue but it was the only way I could figure it out. I hope this helps
