great info david.
xtant was another great company that made some killer products in the past, but sure don't hear much about them. seems like everyone wants tons of clean power for no money(myself included), and that has driven all the american made "overbuilt" amp lines either out or just the spl circuit.

I'm sure that david, phil from kicker and brian from exile could entertain some of us "younger" peeps that grew up with the late 80's companies that pushed mobile audio into what it is today and how many are now either defunct or importing offshore mass-produced stuff...

lanzar
phoenix gold
orion
ppi
linear power
autotek

and the list goes on....
