I have to say I was shopping for a while trying to find an amp that would give me the power i need with SQ. although this amp is not CEA 2006 compliant at 14.4 volts it will put out the rms it claims. It makes my 2 10" in a ported box bang hard but also sound good. The amp does not overheat at all for me.
I have a friend that has the hifonics colossus amp with two 12" MTx 9500
And that amp makes those subs work. I'm just giving that as an example that surprisingly enough hifonics is top quality stuff. If you have concerned if hifonics is what they advertise I can yes it is. To tell you the truth it's the name when you buy kicker or alpine.. A lot of people have those brands so that's why most people will over look hifonics. It's a win win if you buy hifonics you save money. A lot of money then take that extra money and upgrade to a better sub or maybe a nice pair of infinity component speakers. The last thing I will say

Hifonics does make cea 2006 compliant amps and either way you can't go wrong
