That's the point that i'm making. It wouldn't make sense to me for an amp to play so high. I never said I believed SSA. Quite frankly I think that its crazy that no one say corrected the mistake(no offense to the I.T. and web designers). Also, I find it funny that someone had to go as far as name calling and such. I mentioned that it was 50hz, because I was 150% positive that it was wrong, and hoping that someone would correct it. Just think if someone didn't know about this forum, googled car audio, found SSA, read the wrong spec, and thought that it wouldn't dig deep. Now I know that you maybe thinking that this is unlikely, but it can very well possibly happen. I am not arguing that Kevin's specs are wrong at all. Especially considering that Skar is known for that gut wrenching deep bass.
