solo x 12's need 5-6 cubes each? //content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif
give them 2-3 each ported
don't do solo x sealed .. why would you ever do that?
I put my single soloX 10" in a 3.5ft^3 box and was doing 144+ new TL music dash car sealed. 145+ 37hz burps //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif . daily box and power tuned to 37hz I suppose... thought it was 35 but I didn't calc the aeroports right with the flares only half counting //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif but still loud //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
your gonna have problems fitting a second alt on that northstar, if its anything as cramped as my seville was. I wold definately go for one h.o.
I ran 4-12's sealed in that car and it fit nice. 1.6 cu ft per chamber. i think 4 15's sealed wouldn't work. I would go with two bad *** 15's ported. Or those solo-x 12's.
