here is the list
the most common was the pioneer odr system with the processor
followed by the alpine F1
then eclipse and sony.......yes sony but the older top of the line unit (like about 2 or 3 years old)
mcintosh
but the msot common one seemed to be the pioneer odr system which is about 1600US retail and they dont make it any more
it has been replaced by the newer model i eh sure bout d price
as i was judging sound q i tried not to look at the installs and equiopment so i can be unbiased in my scoring
actually i did not look at any installs until i was finished jusdging all the cars that i had to in the ISQC
what i did get to see were kicker eclipse jl jbl dls pioneer focal
jl subs nakamitchi spoke to a few of the guys and they said the nak was great but too sensitve to abuse and the transport mechanism use to stick now and then
