I recently changed my radio because the cd and cassette stopped working on and off. But the main problem was the passenger side front speakers would also cut in and out, like if they both were blown. Problem is even after i changed the radio and the speakers, even the new ones did the same thing, so any suggestions on what this might be?

 

Did you change it the factory stereo out with an aftermarket one, or go with another OEM stereo? I would check the harness, could have a loose or faulty connection. Is it all of the passenger side speakers? The front passenger speakers? Tweeter and woofer?

 

I would track down all the wires on the speakers and check them for splits,etc....
