Well i keep wanting to get JBL amps because of their price and decent quality but people keep steering me away because they dont have the cleanest of sound and they dont have any or good subsonic filters. I decided to get a Precision Power for my Focal components because i wanted really clean power...or would a jbl with a crossover be just as clean? What kind of crossovers could i add to a JBL 1200.1 to get the best sound out of my subs? Im really lost on this stuff. Any help would be great!
