well not only spl but opinions aswell,
ok my mind was kind of set on running either 4 18s (currently running 4 15s)
but ive heard from people they get loud on just 2 Really good 18s on good power & a great box to match
so what do u guys think im in a astro van so space for box is not an issue, for power i have dual alts 250amp each 4 cnd 400s welding wire & a crescendo bc 5500..
i can either just go with my original plan of 4 18s entry level, or i can try an achieve my goals with too good 18s either like a lvl 5 or 6 or pretty much 2 of any of the top series in any brand...
can i get some input? if u or anyone u know has experience with astros your help would be appreciated..
(dont know how true it is but guy told me his buddies hitting 60s with only 2 18s)
