Miguels Posted November 24, 2014 Report Share Posted November 24, 2014 2 12s is more cone area than 1 15. 3" coils more efficient than a 4" also. One team sub is cool but 2 zv4s isn't exactly super usual eitherhow did you figure a 3 inch coil is more efficient than a 4 inch coil?Less moving mass an 18 has more moving mass than a 10.. why does an 18 sound louder? i know why.. just asking since you say less moving mass is more efficient. 18 has more mass than a 10 Quote my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...

Pro7 Posted November 24, 2014 Report Share Posted November 24, 2014 I've just always had the impression that 4" coils advantages don't normally become apparent until they are able to thermally handle more power than their counterpart 3" coils. I could be wrong too but that's just what I've always thought Quote I've gotten a blowjob and picked up my iphone behind her back to see what email notification I got from smd before Link to comment Share on other sites More sharing options...
OrionStang Posted November 24, 2014 Report Share Posted November 24, 2014 OP, you gonna buy an alternator, or just rely on your battery bank and stock alt? With a good alt and an upgraded underhood battery, you should be able to get by with only 2 3100s.

hoit Posted November 24, 2014 Report Share Posted November 24, 2014 ^^this. 2 12'' z's, hoa and a 3100 or 3400 under the hood (the biggest that will fit), and one 3100 as bank (or two to be upper safe).

mcfalcon Posted November 24, 2014 Report Share Posted November 24, 2014 This is going in a Nissan Cube. Weight is gonna play a factor with batteries going with 2 team 12s. I figure with 5k I'm gonna need 3 3100s so I'd basically be doubling my weight going that route Im sure someone makes upgraded shocks. Quote Still learning but have started gathering.

coh33dkill3r Posted December 13, 2014 Author Report Share Posted December 13, 2014 (edited) I talked to sundown and they said there "opinion" is 2 zv4 over the sound of 1 team. So I'm shooting for 2 zv4 12.. Don't have the proper airspace for anything bigger unless I c-pillar wall my cube... Would love to do 2 15s but at 4.25 cuft a piece id have to wall it. Right now my max is 40W x 31H x 18D Edited December 14, 2014 by coh33dkill3r Quote Link to comment Share on other sites More sharing options...
