[QUOTE="poltergeist187, post: 8395348, member: 666284"] Greetings, First subwoofer install in a long time. Ive got what I assume to be decent gear, but yet I feel a lack of both SQ and SPL... Have I missed something? Wrong box, wrong amp, wrong...????? 98 accord 4dr Pioneer entry level deck (2V pre) JL HD750/1 amp 2 x JL 12w6v3 in their prefab box (cs212g-w6v3) 4awg wire ran gain tuned with a DMM with 50 cycle test tone cd to JL spec comparison is that originally with the new JL amp I was running a single old kicker L5 in a kicker ported box that sounded ok, but I was not impressed. Thinking I couldnt go wrong with JL i sprang for that box above mentioned (cs212g-w6v3)... well output is extremely similar if not slightly lower at the frequency where the ported box would "hit". so question, do i need a larger amp? or do I need a fancy box like a 4th order bandpass etc? any help or opinion is appreciated thanks [/QUOTE]
