I have a 2005 GXP and I am thinking that I lost a channel on my amp because the drivers door speaker makes no sound and the other 2 front speakers pop at higher volumes (if the amp isn't the problem, please give me ideas). The problem I am having is that I would prefer to replace it with the factory monsoon amp because I have heard other amp will lose the dash speaker and I am finding plenty of the amps for sale but none of them match the part number of 10395208. I found one with part number 10340134 for a good price but will that fit? Or is there an aftermarket one that will work?
