Have '06 Toyota Avalon and would like to upgrade stereo. I have in years past always used (for some reason) Alpine head units, and Rockford Fostgate speakers, subs and amps. Liked everything but sound of RF mids & tweets. I am a quality over quantity listener. (Home audio - I love sound of Klipsch speakers if that helps) I just can't believe how many brands in audio now...its been awhile. Any help or suggestions is much appreciated. How do some of the "cheaper" companies products compare?? At this point I would like to keep stock head unit, would like a Kicker L7 12" sub......that's where I am at. Need ideas for amps, mids tweets. Thanks to all.
