Mids and Highs

This is the perect amp for mids and highs if you have a good set. This will be a waste on a bad set of mids and highs. I have a set of kicker mids and highs and even with my bass as loud as it is, this amp lets my mids and highs get so loud I can still hear the words. Only negative to this amp is you better have the room for it. It is quite large, but if you do have the room for it, get this one.
