Try someone elses amp and see if it does the same thing. If it still does then try the sub. If it still does it then you have a bad wire somewhere. The possibilites are wires, sub or amp not that hard to trace down.

 

Thanks for the help it was the sub. I used the same box just switched out the 10" unforuntaely I brought a Sony Xplode and everybody is saying that those are crap so I will wait if it blows then I will get either a pioneer or calarion 10" let me know what U think.
Boy, is it hard to hook up your car when you have a wife that watches the money like a CFO of a fourtne 500 company LMAO

 

LOL yea sony sucks man. There subs seem to blow easier than a cheap hooker. That is what I bought when I turned 17 and had my first system. Thank god for best buy warranties. I went through 4 of them at least. I also blew 1 sony amp. I also toasted 2 sony head units.

Now I have memphis amps, memphis door speakersand audiobahn subs with a pioneer head unit. These subs hit so hard. They make your throat hurt and ears ring if you turn it up too high. I would def. recomend audiobahn subs to someone.
