I have a soundstorm amp 100w and 2 12†subs connected to it. The sub says it can run safe 500w 2ohms so that’s how I have the subs wired. Lately the subs haven’t been workin correctly they turn on and off randomly. I conected my phone fraught to the amp and it didn’t be power the subs. The amp was on though. ALL cables are secured and wired correctly. Does that mean my amp isn’t giving out output? Also I think one of my subs might be going out because it scratches sometimes, will that cause them both to go off since they’re wired parallel?
