I have a complete aftermarket system in maxima. 3-way pioneers inside with a pioneer headunit. A RF amp that runs 2 RF 10inch subs and a 4 channel Alpine that powers the 4 speakers inside. Its worked fine for about a year now and now everytime I come to a stop, the passenger speaker gets all distorted. If i turn up the volume alot the distortion disapears even when I turn it back down. I never have this problem while the car is in motion.

So I'm thinking that with the car at low RPM's I'm not getting enough juice to the system and the reason the passenger front speaker is crapping out is cause its the farthest in wire distance from the Alpine in the trunk. How can I go about fixing this problem? Do i need a new battery? A new alternator? or is there a simple fix?

 

Something isnt quite adding up. No you dont need a new battery or alternator. If its just that one speaker and youre sure your wiring is fine, you might try replacing that speaker with another and see if it still happens. Eliminate whatever might be the problem one by one. Because theres no reason for crazy distortion simply with low RPM, or simply because that speaker wire is longer than another. Speaker wire could shift spots when in motion so as not to ground out if its grounding out when you come to a stop...its really hard to narrow down the problem with the given info. But try that speaker first, if not then make sure no speaker wire is grounding out, switch channels on the amp to make sure the amp's channel is not the problem, etc etc etc. Like I said eliminate one by one.

Hope that helped

Yeah, it's definitely a wiring problem. Probably a loose connection that comes apart under braking force, or the speaker wire might be pinched somewhere with the insulation rubbed off, allowing the bare wire to contact the metal of the car.

 

MaxSport you dont happen to have a digital multimeter do you? continuity test for grounding out of speaker wires?
