this is what i got installed. B4 i bought 2 more subs.

600watt Sony amp.
X2 Pinoeer 450watts subs.

they work best kind till i fooled around with my 2 new subs. i tryed to hook all four subs to one amp i tryed to hook 2 of my old subs from one Termainal(this sub has 2 for left and right sub).I started it up with only 2 subs on one Termainal. I blew a fuse in the amp wireing kit when i touched the + and - of my new subs on the wrong thing lol(hit the + on the right side and the - on the left), i fixed the fuse but now my old subs sounds like theres paper inside the boxes. and i gets lil bass. could they be blown? or could i have wires mixed uplike + and -. If there blow ima be mad lmao

 

Sony amps aren't known too take abuse too well . . .
Since you blew a fuse, you did make an oops!
Since the fuse you blew was on the power line and not a fuse on the amp makes me afraid that your amp didn't have sufficient protection and that you may have blown your amp.

Take your amp to a shop and get it tested. It sounds to me like you blew some of your internal components - and that "paper" sound is likely the sound of your amp feeding a distorted signal to your subs. Don't keep running that signal because that will blow your subs, even at low volumes.

 

I am with Maltese on this one. Sounds like you overloaded the amp and blew the internal circuitry. A good amp would have shut off immediately if something like that occurred, and the XPlod stuff is not on that list.
