Re: radio has no sound
Most amps are under the drivers seat or passenger seat. Or even bolted somewhere in the trunk. I doubt it would have an amp though unless there is evidence there may be one in there. Try using this link to retrace your steps:

I wouldnt go to the shop, if you need hands on help, go to an audio installation shop. You might also consider getting online and consulting crutchfield.com. The easiest install is to make sure you have the right wiring harness adapter to match your new radio to the model vehicle your doing the install. This will make sure your wiring is all correct. The wiring for the speakers, if not using the harness, is usually best to just run the wire straight to the speaker. Bypass the whole stock wiring. Especially if your using your own amplifier.
Hi Bob, Joe got in first, because that would have been my advise exactly! Find the power feed to the amp and then do what Joe advised. (Of course the choice of where you fit the switch is yours, you don't have to have it by your seat but it makes sense if you're driving alone) Regards John
it is a possibility that it can't be done that way, after market radios usually have to be wired into the wiring harness they don't just plug in for the simple reason vehicle manufacturers want you to use their radios & equipment NOT after market radios etc , you may have to get a auto radio installer to fit it for you otherwise if you don't know what you are doing it could be more costly in the long run......hope this helps......cheers.
in any post - 2000 gm vehicle, the body body control module routes some signals through the radio., the door chimes and any warning sounds, etc. you need to buy a special adapter to retain these features, available anywhere that sells car audio.
It hard to say, it could be the radio itself not putting out any sound or it could be the external amplifier. assuming the radio work fine, than it will be the external amplifier or visa-versa. the radio out put low frequency sound which we call it pre-amp line which run to and connected to the ext. amperfier, ext. amprefier then amplify the sound to the speakers. if the ext. amplifier if faulty than you will get no sound even though the radio is working properly. hope that make sense..good luck, if you need to replace the stock ext. amplifier, check on ebay for good deal, don't buy it new from a dealer, will cost you arm and a leg. you can also just replace the new entired radio systems (after market) but use the same speakers.
I have come to find out that in the 90's auto makers started installing factory amplifiers in their cars so they could use low wattage stereos in the dash. It's usually a blue wire off the stereo that runs the amp, maybe it couldve become disconnected? I also know that even if you put in an after market stereo, this wire must be hooked up or you'll get no sound from the speakers. hope this helps.
