Has anyone ever heard of these amps? I'm interested in the MB Quart DSC 4125 that's talked about here but I checked out the Vibe Slick a4 4 channel on Frys.com which is rated 150 x 4, 500 x 2 bridged listed for $179. The price went down from $299 from a month ago and I'm just wondering if this amp would be comparable in performance.
