Report "Purchased a new ifonics 1206d amp and new subwoofer. had all installed professionally by local sound store. amp would go into protection shortly after leaving store. brought back and they told me amp or subs were "possibly" bad and wanted to chg 50.00 to check it. declined his offer. after few days, amp started cutting off...wiggled small 18g remote wire and amp would come on and off. brought it back to them, they restripped wire and reinstated it. worked for awhile, then stopped. now when remote wire is inside, the amp powers on, but no sound from sub. any sugg?"
