Aftermarket radio no sound

[Sbc_mafia]

I had a touch screen radio installed in my 2005 sierra that would act up here and there. Today after I got gas and started the truck the radio had no sound to door speakers. The subwoofers worked but no other speakers. I put the stock one back in and the speakers worked. So I bought a new radio and wiring harness and tried it again with a decent kenwood. Still no door speakers on after market one

Does your Sierra have the Bose system? If so, I believe you need a specific adapter.

As far as I know it doesn’t. When I bought the truck it had a cheap head unit and kicker speakers in so I’m not sure how to tell if it does

When you go to start the truck, turn the key to "ON", and wait about 5 seconds before you start it.

Will the speakers work if you leave the key in either "Accessory" or "ON"?

No they won’t. The part that confuses me the most is. I’ve had the touch screen in for a few months and they worked fine. You can hear the speakers making a pop when you turn the key on with the aftermarket one in then no sound besides woofers

Hard to say without seeing it....If it did have the Bose system, they generally use a seperate amp.

I assume you have an aftermarket wiring harness for the GM wiring to the aftermarket radio? If so, check the blue wire, that is usually the remote turn on for any added accessory like an amp.

Odd it just stopped but works with the stock radio.
