When i got this thing home i ran it in as you do and then i gave it a pounding and like the reviews on the 12 inch modle it would cut out and then back in when it cooled down, well i took it stright back and asked for a repair, the repair was a new amp and i don't think cerwin was happy because the stockest stoped stocking them after this repair.
Any way now it goes hard and keeps going there is no stopping it and it goes so low you dont even hear it just feel it, at full volume it huts your ears and distorts your vision, during movies it is strong even at low volumes and if your fill speakers are big and strong it mixes very well, it is a sub that needs a lot of space around it to get the best from it, it is good with all music i found and can cut it below 20hz with out breaking a sweat.

If you have close neighbours forget buying this sub the noise that can come from this sub will be heard from 3 to 4 houses away(DURING THE DAY)at night i would double that # easy.

I like it it's strong it punches it rores it dips it rumbles and hope it never dies.....LUV IT.
