Playa Named Joe Posted March 17, 2010 Report Share Posted March 17, 2010 I would think that the 4 15s L7 might be louder, because of more cone area. But you could get the 18s moving like crazy off one 2500 a piece. Quote 1994 Pontiac Grand Prix build Link to comment Share on other sites More sharing options...

Brandon15zzz Posted March 17, 2010 Report Share Posted March 17, 2010 The 18's would have more cone area look at the chart derrick824 did, thats pinned in the subwoofer section also i would just think they would be louder cause of the power difference. should beat though start a build log when you begin. good luck Quote Vehicle: 1995 Impala SSHead Unit: Pioneer AVH-P4400BHMids And Highs: (still deciding)Batteries: 1 Deka Group 34 Time to make a race car.My Build Log: Solo X 12"http://www.stevemead...don15zzz-build/My Build Log: DC lvl 4 xl 15"http://www.stevemead...don15zzz-build-My Wall Build Log: 4 Lanzar 15's/ 3k+ RMShttp://www.stevemead...t-by-techforce/My Feedback:http://www.stevemead...1 Link to comment Share on other sites More sharing options...

bobonit Posted March 17, 2010 Report Share Posted March 17, 2010 But aren't your 15's square? Square cones have more area than round ones. Quote 97 Maxima SE Bunch of shit going in, check out the build Build Log Link to comment Share on other sites More sharing options...
crazyfrazz09 Posted March 17, 2010 Report Share Posted March 17, 2010 yeah i thought the square subs have the cone area of the next size up in round.... example a square 10= a round 12. and so on.....

crazyfrazz09 Posted March 17, 2010 Report Share Posted March 17, 2010 im not sure but i think the kickers will take that kind of power daily better than the 18's you have.

Fre3zErBurN Posted March 17, 2010 Report Share Posted March 17, 2010 I would say go with the 4 kicker L7s with that power they would absolutely pound. Quote Link to comment Share on other sites More sharing options...
