I have a 2004 Club Car Precedent and was in the process of improving it. I recently bought for my car audio and video system. While I was installing my ground wire from the chassis to the amp some of the wire touched the power wire and sparked. My amp still turns on but barely pushes my subs. So I was wondering if I need to buy a new amp or just re-wire everything. Any suggestions will be dearly appreciated. Thanks in advance. Have a nice day.
