Hi, I was wondering if anyone can help me with my subs they seem to not hit as hard as they should I don't know what I could have done wrong I made sure all the connections are right and tight. I tried hooking them up in a buddys car with his amp and they work fine there even tried his amp in my car and the same thing happened now this has happened in my car and it's happening in another buddys car and we can't seem to figure out the problem any help would be greatly appreciated!
