I have left this amp on for a full 24 hours or more in my car not once but a few times. After i noticed it being on, it was just a little warm nothing crazy. Then using it all day after the fact it was on for hours, and still not getting very hot is pretty freaking sweet in my book!

previously i was running a power acoutik ov-2200 2 channel on my kicker 15" cvr's, then it short circuited and wouldn't shut off, and was draining my batteries so I sent it back along with a few other things and purchased this amp. For being so small, its pretty strong at 2 ohms, its almost a perfect match for my 500rms kickers, has made my rearview mirror fall off numerous times before i used lots of 3500lb epoxy, plan on getting another one of these and upgrading my subs as well, very good amp, looks nice and stays cool even after a good hour of punishment

This is an amazing amp! Although its stats. on paper my not be as impressive as some others it will out last and out perform anything Competitively priced. hands down. The only thing that would make this amp better is if they made a digital version of it.

Customer Testimonial

I tried the Tech Support, my luck with this on many other sites is pretty hit or miss at best. To my surprise, I received a response in less than two days and it obviously showed that someone with some intelligence and knowledge actually carefully read what I wrote and made a reply that made sense.
