I am building a new set up in my 2000 Chevy Tahoe I'm trying to figure out what subwoofer and amp combination to put in there my old set up in my 2000 jeep cherokee was 2 sundown zv4 15" on a powerbass xta 5k. Im looking into PSI, DC, Fi, and or back to sundown. It will be everyday use but wouldnt mind a set up that could be wired for a little competition. Any opinions on sub and amp set up would be great!
