Ok, right now I have a Pioneer Premier 470 HU, 4 Pioneer 3 ways, a Kicker 450.2 amp with 225rmsX2 power, 2 RE12's, and a sealed box. I was wondering if it would be worth it to upgrade both the front speakers (to Alpine Type R components) and to upgrade the sealed box to ported. Would the bass increase a TON? Would the SQ remain the same and would the "punchiness" of the subs remain the same?
