Kenwood? Pioneer? Alpine? Rockford Fosgate? Pheonix Gold? MTX? Etc etc... I don't know what's good and what's bad. When I look at car audio advertisements, I see parts from different manufacturers mixed together in different combinations. Can I simply concentrate on one company and find everything I'm looking for, or must I mix and match? I don't know much about this stuff, but I think Kenwood and Pioneer are both decent. Any suggestions? I'm hoping to build an affordable system with outstanding bass. (and great sound in general). I'm thinking of spending maybe $1500 Canadian (about $1000 US). Thanks, Jonny K.
