hey i just bought a new kenwood stereo for my 97 mazda protege lx. Everything works fine power, rear speakers, except im having a problem with my door speakers, sound comes out of them but it is really low and scratchy, but my rear speakers work and sound fine. Anyone have ideas on why they are doing this? The door speakers are brand new 240w kenwoods that worked when i had my stock stereo hooked up, and my back speakers are a third party brand 200w 6x9's

Thanks

 

check your wireing that you did in the back of the unit when you wired all the speakers to it tug on the front speaker wires a fair amount it if pulls off thats your problem cause the way it sounds its a wireing problem, check to make sure your + wire is going to + speaker wire and so on.
