I just recently install my amp and subs after not using it for a year. At first i connected everything and the amp works and sub was hitting. But i played around with the wires since it is not hitting hard. I accidently hit the ground wire that is connected the metal chassis and a couple of sparks arise. Since then the amp wont work. I tried reconnecting the remote wire and power wire. Only these 2 wire should power the amp. Do you think i short circuit the amp. Its not working nomore. What are your guys suggestion to resolving this problem . Thanks rob
