No sound comming out of speakers

No, you can't normally do that because the radio is controlled and monitored by the Body Control Module (BCM) on a 5 volt computer network..

Did the AM stereo come with a wiring harness or adapter to match up with your T&C OEM stereo? If so, look for loose or poorly mated connectors. If not, double-check that the wire splices you installed are secure. Are you using the T&C's original speakers, or did you install aftermarket speakers, as well?

Some things I would check are do you have blue tooth in operation. Do you have any form of michrophone in the cab as it sounds like a feed back problem coming through your speakers. Talk to a radio techie to see what he thinks

Depending on the model, the Silverado may have an amplifier between the OEM radio and the speakers. If that is the case, you will have to remove it and wire directly to the speakers. Check the wiring schematics for the original truck radio option (one source is Alldatadiy.com).

either you are running an aftermarket stereo with too much power for the OEM speakers, or your OEM radio has malfunctioned and there is stray voltage getting to the speakers. in the prior case you need to upgrade your speakers, in the latter case you need to look around and find a replacement used working OEM radio. used OEM radios can be had on eBay, at junkyards, at stereo install shops, and by looking around on craagslist, to name a few.

look on youtube.com for videos of folks pulling a dashboard, console, stereo, or speaker replacement on your vehicle. Or you can buy a repair manual which can be had on CD for about 5 bucks on eBay.

Hello my name is Israel and I will try to help. Assuming that the radio is a factory installed radio, I would try to get an extra speaker and go to each speaker location to check if you have "power" going to each speaker. It could be that the speakers have gone out. If the radio is after market you could do the same, plus also check the connections behind the stereo to be sure that they are secure. Good luck.

My mothers 96 Tahoe did the same thing last year. It was a blown speaker in the rear causing her problem. Hope this helps.

Did it fail while you had vehicle, or like this when you bought it? Could be bad radio or wiring harness was chopped up when previous owners had an aftermarket radio installed. They probably just slapped the OEM radio back in when selling car. And didn't put all the OEM wiring back in.
