Really great amp!

I got one of these powering 2 mb quart 10" square onyx subs, plenty of power, sounds great! its good that mb quart kept true quality like they where in the 90's.

pros: sounds amazing!
gives true power!
easy to hook up!
looks pretty neat.

Cons:
It gets pretty hot at 1 ohm however, not like "hmm this is pretty warm" its more like "wow i cant keep my hand in it" hot.
needs more cooling fins.
its hard to stuff 0/1/2 gauge wire into the power/ground terminals
power/ground terminals are pointed down?! why...
remote terminal its really really big for a remote wire.

overall, the pros outweigh the cons by a ton. i would recommend this to a friend, and i would buy again in a heartbeat.

Good amp overall

I have this amp paired with 2 Pioneer 12" 4 ohm SVC subs so it's running into a single 2 ohm load and it works excellent. Plenty of power and doesn't get super hot or shut down. The only problem I have had is that the fan inside the amplifier started buzzing in the winter and I had to send it in for warranty replacement. This was done quickly though and communication from Maxxsonics was great.

I was a bit hesitant to purchase the amp because in reality it is a Hifonics amp with different badging but it has performed above my expectations.
