I bought one of these recently and i must say they are good amps to begin with. The one i bought wasn't working right but was an easy fix to get it playing again. It sounds real this amp even at high volumes its the best. It can power your mids and high real crisp and clear or a set of subs like two small 10's or low powered 12's. I wouldn't recommend as a sub amp because it can get real hot and may fail on you. I'd recommend this amp (200a4 & 400a4) because of power and strength and not to mention very compact and really easy to install but you will need a fuse in-line with B+ wire because these amps don't have on board fuses. - Keviniswack
This is a great Rockford Fosgate Classic 4 Channel Amp that is certainly capable of powering any combination of speakers such as door & rear deck Speakers. Also can power a set of subwoofers. This amp can configured for highs & subwoofers with the on board crossover sending the appriate frequencies to the connected speakers. This amp is a breeze to set-up; You be enjoying great music as soon as you are through with your connections.
This is a sweet 4 channel amp. This is a old school amp has tons of power.

This is a great amp for its age. Maybe, better than the NEWER amps. It put out great sounds, and is compact. Not to mention, Very underrated in its power. This amp was made when Rockford Fosgate was on top of the Car Audio world.
