Hey guys, recently I have upgraded the speakers in my 22 Prestige with the Harmon Karmon system. I messed it up because I think I switched one or a couple of wires (positive/negative) and now the system doesn't sound as loud and I lost some of the bass. I have been looking all over the internet for a colored wire diagram or something to tell me what wires are positive and negative on each door. Anyone know where I can find that information out? If anyone has insight please let me know
