Cheap, simple to set up. Works excellently. It is a little large but still well concealed under the passenger seat of my '04 Camry and never ever has any heat issues (probably owing to the size). Hook it up for a full front stage sound system with subs and forget it exists. Just what I wanted. Also, I don't see the lack of crossover flexibility as a real negative. Most amps give you enough rope to hang yourself. This really has enough to cover what one would need in 99% of cases for 99% of the public.
