rock solid

This replaced my zapco studio 500(mid-bass)+studio 300x(mid-range) which have held up well for 15 years. The rockford gave me the extra headroom/power needed to Really get the up front bass power to make the system blend smoothly with authority! The amp is quite heavy and ratings are conservative. The amp does get quite warm though due to the small footprint of the amp. Overall very happy so far.

Excellent single amp solution

I bought this amp to replace my JL HD600/4 and HD750/1. I had the HD600/4 bridged for the SPZ60's running passive in coax mode. Now, all I need is this one amp to run everything. It sounds just as good and I only need one amp now and it is a lot less money. Also, I have dual SRX10's in the back which I run bridged off the rear channels of this amp. This is a very heavy amp and is rated at 1400 watts so it needs a 150 amp fuse. I listen to rock and death metal and I would highly recommend this amp. The only thing about this amp are the controls are on the bottom, my JL amp controls were on the top. They were easier to get to than this amp. Just set the controls before installing. Hope this info helps someone out there who is on the edge about buying this amp.
