Great bang for the buck, very common these days in multi sub setups running @ 1 ohm. I personally like it, although mine do not get hot because I fixed that problem with a cooling fan setup...overall a very good amp.
the amp does not put out any more power at 1ohm like most amp, the only way to get some more power out of it is a get a biger alternator or a cap then the amp wile give out about 1400 watts.
