Radio works, aftermarket,speakers will come on then,cut off no sounds this is the second radio that comes on then does nothing
. If you hit a certain bump it comes on then goes back off

The dash lights and the rear running lights just stopped working. We changed the fuse cause it was blown but not they arent working again and the fuse is just fine. The only thing ive done different recently is installing a stereo. So im wondering if maybe a wire got pinched when i installed it. Any advice welcome.
