GenVibe - Community for Pontiac Vibe Enthusiasts

The passenger side door speakers, both front and back, in my vibe recently lost their ability to produce any bass. I can hear sound coming out of the speakers, but they are a bit muffled and sound as though they are exclusively coming from the tweeter. I am not sure if it is the amp (moons and tunes) or something with the speakers. I am trying to avoid going to the dealership and paying the $45 diagnostic fee.Thanks in advance for any help!

I think if it was the amp there would be no sound at all. Hard to say though, as these amps aren't like normal amps.

What year is it? Would it still be under warranty? Only way to tell if it is the speeker is to test it.

It is a 2003. If it is indeed "blown speakers", I can't believe that two of them on the SAME SIDE of the car would blow at the same time. My friend said that it might be a blown channel on the amp.

Some amps have fueses in them and inline fuse in the speaker line. Could be a relay also. I would check the amp
