August 11, 2008 Great Amp For The Price!

This amp is CEA Compliant. Im pushing it at 2 ohms right now. It does not get hot like my friend's amp. The 9103 is fan cooled and has sweet blue lights around the fan. The bass boost, gain, etc are all under the metal plate. That's kind of a con.

I totally recommend this amp to anyone who is going to push 900W RMS. Wire it at 2 ohms, and wow. I was blown away. It sounds great at 4 ohms as well. The amp is even 1 ohm stable!
