Huge amount of power

Its a boat anchor weighing in about 50lbs.
Very dependable compared to hot and over heating digital power amps which are terrible.
Lots of bass, lots of everything. There is some THD but you have to
expect that from 800 wpc. I ran mine for 12 hours straight at a Octoberfest event without a hitch. Highly recommend for the price and power.
