Nikitaaa Posted September 7, 2013 Report Posted September 7, 2013 I had an 18" sub in the trunk. (sorta). I do not suggest it. 2 level 4 or XL 12s in a proper box will give u just as good, if not better output then 1 level 5 18 in a trunk.The 18 will out preform the 12's given both have proper boxes.

Cone area is king. I would have to disagree, in this case 2 12s would have more room to breathe. An u can fire the subs am port into the cabin an seal it off. Unlike the 18" u can not do that if u want to keep it all in the trunk. My build 98 s10 2.2 3 american bass HD 15s with psi soft parts.

newschoolsoundz Posted September 7, 2013 Author Report Posted September 7, 2013 you said cone is king but said the 18 will out preform the 12s when the 12s have more cone area lol
Nikitaaa Posted September 7, 2013 Report Posted September 7, 2013 Touche.. assuming he doesn't have the height to run the 18 port and sub forward sealed;) 2007 M/T Honda Civic Coupe EX (4) Sundown Audio X-8's (2) Ampere Audio 3800.1's (3) Stinger SPV-44 Batteries (1) Mechman 240 3:1 Ratio 4th order sealed from the trunkTEAM NWSPLBest termlab scores to date in Honda trunk:151.7db legal (official) IASCA trunk 3 classBest termlab scores to date in my walled Subie:152.9db legal (unofficial) IASCA advanced 2 class155db outlaw
newschoolsoundz Posted September 7, 2013 Author Report Posted September 7, 2013 regardless if i did or not i couldnt seal it off due to the opening where the seats fold 12s would barely fit sealed off
zydrix Posted September 7, 2013 Report Posted September 7, 2013 Touche.. assuming he doesn't have the height to run the 18 port and sub forward sealed;) That is also true. But most cars dont. I guess it just really depends on the car. In my case my 18" sp4 didn't out perform my hdc3 12s on same power. My build 98 s10 2.2 3 american bass HD 15s with psi soft parts.
