The sub brands I was thinking of were image dynamics and Treo.
For door panel speakers I was thinkinh of Hertz, MBQuart, and Treo.
I purchased the Hertz and Treo speakers (treo for the rear deck b/c they were cheaper) and the Image dynamics sub. I never heard the mbquart door panel speakers or the Treo subs but he had a lot of good things to say about them (and reviews were postive as well.)
I am not sure if any of these brands are actaully better than say a 3-way pioneer door panel speaker because I never did any A/B comparison... but I can say that I am pretty happy with the sound of the hertz speakers in particular.
