4 12s or 2 15s

I'm wondering which of these setups will yield the best results. 4 12" pioneer premier champion series 12, 4 kicker cvr 12s or 2 American bass xd 15s. I have about a grand Marquis so about 7 cubes to work with and I want the subs firing up. I have a 200 amp alt, big 3 already done, kinetic 1200 cell, 2012 photonic Brutus brz2400. Any help will greatly b appreciatedLife is what u make of it so make the best of it

By "best results" I assume you mean "get loudest"?  That's largely dependent on the enclosure, but just looking at the sensitivity specs for the woofers, the Pioneers are 2db more sensitive than the Kickers so you'd get better power utilization from them, and the 15's will move more air.  The enclosure will determine your net SPL though.  Is this a daily driver?Support the12volt.com

Correct on being the loudest. Sorry about that. But with any of the enclosures I would want the subs facing up and the enclosure vented, also pointing up as well. And yes this will b dailyLife is what u make of it so make the best of it

its impossible to tell you which system will be louder because there are just too many variables to consider. my personal opinion is i tend to lean toward the simpler systems so i would go with the 2 15's.  kicker cvr's are cheap subs that dont hold up to abuse very well.

also its easier to design a box for 2 subs than 4 subs especially if you plan to use a ported box. and a proper box design will make or break your system. id doesnt matter how good or how many subs you have, if you dont have them in a well designed box your system wont be at its full potential.

Excellent advice.  I too would tend toward a dual 15's setup for a daily driver.Support the12volt.com

ok. Thanks for the advice. So would the subs that I am considering be the best "bang for buck" subs? My budget is about 200 per woofer, but I have heard the xds in a sealed enclosure before and they were pretty deep. Any other sub suggestiinsLife is what u make of it so make the best of it

American Bass subwoofers are made for them by Eminence so they are good quality speakers.  I like the HD series, but not sure what they sell for these days.  I've never heard the XD that I know of.Support the12volt.com

also the fact you will be splitting amp power only by two with the 15's and roughly 3.5cuft per basic 15 should be good..
