What do you know about the brand "Solid Audio" in the car audio industry? - svc subwoofer

I can not find your website or something of the nature. I can only see some information on their amps and wonder whether it is a good company or just cheap stuff.

I have a solid Audio 12 "SVC Subwoofer 500W
American HI-Current Technology
Model: SF 124S (SF124S)

What's your cry? What I would be able to subwoofer? Even a Web site? Is it perhaps to import one?
