sales@newusamps.comthey have no dealers in Michigan though....how much does a md23 cost?
Why don't you get a monoblock sub amp?, it would be cheaper and more efficient then a huge 2channel amp.
Or, if you're thinking of powering components.
Why in hell would you want that much power for mids and tweets?, over powering you're mids and highs can make you system sound shitty (too loud in comparison to the bass, Bad RTA curve).
