Summary: Do your own research. The Sub 10 has amp issues. I have had for a little while now amp is bad. Getting new 500W plate amp from parts express. Not going to try to repair, not worth it. If you want better sound, get a HSU, or at least an enclosed sub and get a full range of sound. Just make sure you have a higher end amp.(power is not everything, design is).
Summary: Bought this sub and have had nothing but trouble with it since. Power issues that the company admits it has since day one and has done nothing about it. I had t pay twice to have it foxed from a third party, ans it still doesn't work. If you research this company and their subs, it will show that the design is faulty and they keep pumping them out. obviously this is a company that is riding their previously good products performance with a terrible new product.
Summary: I went through 2 Of these in less 2 months...so yeah SUX!!!!it did give a great punch but really 2 in 2 months yeah if you want a sub for a day or two its great but for a sub for a lifetime its not the one.
