Solid construction, great performance!

Rockford Fosgate always seems to under rate their amplifiers output and so these amps are no exception.  The one I received shown 468 watts on the birth sheet that they provide for each individual amplifier.  This is good piece of mind as most manufacturer's OVER rate their amps and blow up un-reasonable specs.

Would I recommend this to a friend or family member? Yes
