lacboi Posted October 11, 2011 Report Share Posted October 11, 2011 Im helping a friend with his stereo and we are having the strangest issue. We installed a Hifonics Colossus and it was banging hard that day, now every since when th volume is turned up to daily listening levels it like 3/4 of the output is gone. We have done everything from by passing his crossover adding a line driver and nothing seems to work. Has anyone had this issue or any suggestions on what I should try next?
