It's a basic entry-level 1000w+ sub amp. Nothing special, but it will power a decent pair of dvc 4's pretty well.
The board is several years old, 2000 or so, but there are still some amps using similar versions.
Concept, Lanzar, Boss and Pyramid all had clones.
The Lanzar 1800D is similar. It's $220 or so new, about $150 refurbed.
