I'm redoing my system, getting rid of the crap. So far I have a set of Alpine Type-X 6.5 comps that will be fed off a Kicker SX600.2 with a SXRC so I can fine tune everything from the front, looking for a sx1250.1 for my subs. Right now the subs are just a pair of Infinity 1230W running at 2 ohms in a sealed box but when I save up the money I'll probably go with a ported 12" Fi Q in a 2.5 cube at about 32Hz. For comparison my old system a set of Lightning Audio 6.5 B1 co-axis off a ESA 55wrms x 2 circuit city brand amp, and the Infinity's off a RF P3001.

Should be a slight improvement
