Radio on but no sound after installing after market subs

not knowing what your working on I'm going to guess did you change out stock radio with aftermarket some cars need a radio reset code3.

one of your speakers is blown and shorting out your deck. disconnect one sspeaker at a time and when it starts working fine you know that's the blown one.

this may be the memory wire for the factory unit if putting in an after market radio you shouldn't need it

If your dash has not been modified by whomever installed the aftermarket radio, it should go like this:

Using a flat screwdriver, gently pry the bottom edge of the air conditioner control assembly to disengage the clips (there are 6 of them). Pull the control assebly out and disconnect the electrical connectors and set aside.

Remove the 4 bolts on the lower edge of the radio finish panel located under where the air conditioner assembly was located. Pry around the edges of the radio finish panel to disengage the 5 clips (two on either side and one at the top center) The finish panel and radio assembly will then pull out of the dash so the electrical connectors can be disconnected and the radio removed (again, this is providing that no modifications have been made).

Hopefully, you will find the vehicle wiring harnesses and radio mountings still intact. Many times, aftermarket radio installers will cut and splice several of the wires from the original radio connectors, And modify the mountings to accomodate a radio that was not made to fit the vehicle, making it necessary to repair the wiring harnesses and/or mountings before an original-type radio can be reinstalled.

It sounds like the amp is not functioning on the radio. If you install and after market cd player the radio still won't play because it's the same amp.

Now, if you would change the radio and it still won't play, it sound like it would be the wiring to the speakers. Speakers usually don't burn out, but anything is possible.

I hope this helped.

sounds like a loose connection. do not grade me on this for it maybe internal as well in your unit instaled

the cd player is bad and you can hook up subs through a rca hook up that you can hook to your speaker wires in the trunk the adapter is like 20 bucks at radio shack or local sound installer or buy an after market cd player cause yours will never work again and run rca's off the back of the radio to your trunk
