  • Big fan of RF products. They never disappoint me yet! I currently run this 4ch amp with my 6x9s full range and its very clean and powerful. Hard to beat when its performing this well and its price is so good for what it offers.

  • This is one of the best budget amps you can get and sounds great integrated to most factory head units.
