2200 Watts is the most bass where I've been inside the car, and it was my brother. My brother used to be into car stereos and he even won 2nd place in all of Alberta in a bass/car stereo contest. I watched him install the stuff, buy the stuff and play the stuff. He had 3 JL 12inch subs in his trunk, mids in the doors and center, a power pumper, 1 amp for his subs, another small one for his mids., and a bass cube. The bass cube was the COOLEST fucking thing in the world. It was this small cube with switch, and when he pulled the swicth to on, the bass, and only the bass would amplify about 10x as regular. We had to open the door windows otherwise they would risk shattering. When he entered the contest, his roof was rattling so hard that is started to crack.

It was insane, but towards the end of it all, he had a total of 2200 Watts in his car. It was awesome stuff, but it doesn't really impress me when a car drives by with a loud stereo. Seen it, done it, done.
