### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Excellent value, built very well
  

*by D***N on Reviewed in the United States on June 12, 2020*

This thing is built VERY well, its kinda heavy but that means it does not have cheap parts in it. The sound the puts to my speakers/sub is INCREDIBLE, I had the Pyle 400 Watt marine amp and didn't like it, put this amp in and its NIGHT and DAY difference. Spend the extra bit of money and get this one. This amp is powering 2 Pyle 600 watt marine 6.5" speakers and a Pyle 400 watt 8' sub, the sub is bridged on the amp with channels 3 & 4 and sounds very good, the 6.5" are very loud. Would buy again.

    I love this thing!
  

*by W***O on Reviewed in the United States on October 14, 2016*

This amp is amazing.  I installed it on my golf cart.  After about a month I am still trying to find ways to blow a fuse or burn it up completely.  I have four speakers running at a 1 ohm load to channel 1.  Channel 2 is open.  Channels 3 and 4 are bridged,  currently to a 4 ohm single 8" woofer.  Just got the other 8" today.  Let's see if we can bridge 3 and 4 to a 2 ohm load.  I'd surprised if not.  All told (so far) I have been running off of 3 15aph batteries wired together.  I got about six hours out of it at 80% volume (LOUD).  We could hear the base floating in the lake 100+ yards away.  Very good quality amp thus far!  The PA is just a bonus that matches my silliness. :)

This little thing has some power. I used this amplifier for a pair of 8 inch Rockville wakeboard tower speakers. The sound quality is loud and clear. Easy to install and great on a budget build.
