i thought i already posted this in the car audio section but i did not find the posting. if it is duplicate i'm sorry. but what i need is a schematic for this amp. want to try and figure out what is wrong with it and fix it. what i have is a sony xplode amp model number XM-SD22X. can't find the schematic anywhere. finding other docs that of no use, used google searches and searched here on this site, hopefully someone can help. i thought it would be easier to find a schematic for a relatively recent product, but not much luck. thanks for your time and patience with a noob.
