As I've metioned before, I dont claim to b an expert, just know what I've seen and used.
I think everyone finds there own favorite brand. I have always had a soft spot for Kenwood. I had a $600 system 8 yrs ago that had no trouble drowning out the big block, but then again, a pioneer, jvc, alpine, clarion could have done the same.
I think at the end of the day, it all comes down to personal tastes, $$$ in pocket/credit, and trying not to get screwed over into paying for a name!
Good Luck !!!
