I have just installed this amp on two 12" alpine type R's and wow! this thing makes my whole car flex! most people say that running a setup at 1ohm make the amp heat up more but i can hold my hand on this thing the whole time its playing even when its all of the way. I like that it doesn't draw and excessive amount of power and i can play my car in acc position for about 45mins with my jam cranked all the way. Just get it. It has everything in store!
