So Ive been through 5 different speakers with the same amp. A set of Memphis 10's, a cheap dual 12 from walmart, and a pioneer 12 from walmart. Recently my pioneer busted and I had buy a new subwoofer. After hooking it up it sounds like nothing I've ever heard before. All my other subwoofers had this deep shaking bass that have knocked my rear view mirror off, busted my defroster out, and even cracked my Sideview mirror. Well anyways, I hooked it up and it's soooo weak. Like it can hit the long mids, but everything else is sad. It's just like a bang. It had bass but it's way weaker than my last subs. I'm also using all the same wiring as my others. Please help.
