Real96SS Posted May 24, 2012 Report Share Posted May 24, 2012 Where are you in Italy because I'm also in Italy and I run the BTL 18's.I can tell you that lowering your tuning without adding power will more than likely lower your score also.

memphisBred Posted May 24, 2012 Report Share Posted May 24, 2012 Does that amp do rated and at what voltage? What's your electrical like? If your getting 3000 wrms out of the amp I'd go with 3.5-4 cubes with 55-75 sq in of port.

AudioBully Posted May 24, 2012 Report Share Posted May 24, 2012 I know BTL's love lows not so much the highs atleast the n2's so I'd probably tune a bit lower Quote 02 TrailBlazer Fi BTL n2 18" Fully Loaded DC 1.2K @ 1500RMS 1 Ohm Pioneer 4200UB Pioneer 4-Way 6.5's MB Quart Onyx 125.4 KnuKonceptz Wiring Stock Alternator, Odyssey PC1500DT, Big III http://www.youtube.c...NN?feature=mhee Link to comment Share on other sites More sharing options...
