This is a good amp, it had a lot to live up to as i had a blaupunkt BD2 before this and it used to really thump so i was expecting similar performance and i'm glad to say it does deliver. It is small in size compared to other 2000wrms+ amps but it doesn't take away from the overall performance. There is no external fuses so you should connect your own. I've run 0awg cable and installed at 200amp fuse near the amp as well as near the battery. It needs fine tuning with the settings, but overall its a good amp, not quite up there with the big names (RE, Alpine, DLS) but you'll never get this much power from those amps at these prices so probably the best amp in the league below those "big shots".
