Best bang for your buck!

I actually purchased this a while ago. My first thoughts: what a price! What I also liked about this amp is the crossovers. Really versitile. What I did not like about this amp is that it did not come with a band pass crossover. Having a band pass crossover was what I needed for my setup. But for the price on this amp, you can't beat it.

One thing also, it gets extremely hot. I actually had it in protect once. Ever since that happened, I am more careful about it overheating. Might invest in some fans to keep it cool.

Would I recommend this to a friend or family member? Yes
  • Simple to Set Up
  • Looks Good
