I have an infiniti 12" amped with a power acoustik gothic series 2 channel amp. This setup has been working for months and months but just recently it bugged out and whenever the sub hits you hear fuzz and static. The music still comes through but it is very fuzzy. I have tried moving my ground wire and I checked the entire length of the wires for any frays, kings, or tears and found nothing. When I have my gain turned up and my LPF turned up it seems to want to overpower and it blows the fuses within seconds. It doesn't make sense to me since it has worked for so long before just recently. Any suggestions or solutions?
