I'd recommend this to anyone looking for a top shelf brand like JL but would rather play for a lower shelf item like boss.

I paired this with one 12" W3v3-2
It shakes the s**t outta my 2009 chevy malibu
super loud
super clean

I'd suggest buying this with the dynamat car kit haha you'll need it.

January 31, 2011 Pretty good, but overheats easily
Review by
Carlos from Gilbert, AZ

This amp is running a 10" JL sub rated for 300w. It does a great job in sound quality and power, except that it overheats easily if it doesn't have a lot of airflow. It's installed in the cabin of our boat near the ceiling, but is not enclosed in any way. It creates enough heat that it builds up and shuts down the amp if we don't put a fan nearby to blow air around it. This is while running at high volume, though not overloading the speaker which is only 300w. So if you're looking for an amp to run in an overhead space like a hanging rack in a trunk, this probably isn't the right one unless you also run fans. It would probably be fine if you give it lots of room overhead to clear heat.

The connections are high quality and easy to use. Installation holes are easy to access. Everything else about the amp is very good.
