  • Very surprised.
Unbelievably loud and clear for the price. I'm not sure why the cost is so low for an amp that puts out so much power. It may not have the big brand names as the others, but for the price you pay and the power you get, it can't be beat. I've been installing stereo systems for many many years on my customers boats and this has proven to be a good amp over and over and over. ... show more

  • Bad amp
I bought this amplifier to use in my boat and have only taken it out three times since I’ve installed it. One of the channels is no longer working!

  • Clean bass
High sound quality. Mounted it for my sxs. It has plenty of tunable settings. It's a class AB therefore it'll get warmer than a class D. But it sounds better.

  • might need some good air flow.
Easy install and works great for the cost. Gets really hot even with correct guage wires so I had to install a bilge blower in the center console where the amp is located to cool it. It turned off once before I installed the blower due to overheating but since I put in the blower I have not had any issues. (July-Sep NC coast.) ... show more

  • Great power for the money!!
I highly recommend this amp. I do have to get better speakers that can handle the power. Chose a speaker that can handle power and you'll be very happy!!
