9blazer8 Posted May 7, 2012 Report Share Posted May 7, 2012 hi i had a box made for my 4 door blazer a few months ago and for some reason i have no lows but i have unbelivable mids im thinking the box wasnt tuned properly i wanted it at 28hz thinking i would get some nice lows but nope. so now im asking you guys if you could help me i want it to hit great lows and mids and i wanna use it for daily and i want to have some good numbers. the subs i have are polk 1240 db series i know there not the greatest but its a good start im kinda on a budget Quote Link to comment Share on other sites More sharing options...
PowerHouse407 Posted May 7, 2012 Report Share Posted May 7, 2012 if it was tuned to 28 it should be hitting the lows. how much port area per cube do you have? and make sure all your crossovers and filters on you amp and head unit are set right.

9blazer8 Posted May 7, 2012 Author Report Share Posted May 7, 2012 well thats what i was thinking but for some reason its not hitting them i mean theres some lows but nothing like how it should be for 8 12s this is my first box i had made but this is what i know who knows how true it is but its a 8 cube box so 1 cube for each sub. i just got a new radio so maybe that could be it but before my other radio quit it was alot louder plus i dont know if this makes a difference but i have the subs ran in parallel to.

purplesyrup Posted May 8, 2012 Report Share Posted May 8, 2012 the most simple answer I can come up with, without looking up the specs on your subs is. its very likely that 1 cubic foot per sub is way way to small for those subs to function properly. it is very likely you need 1.5-2.00 per sub ported, going that small will limit the drivers output all together. you would most likely be better off selling 4 of them and building an 8 cuft box for 4 of them Quote Link to comment Share on other sites More sharing options...
DblBelly Posted May 8, 2012 Report Share Posted May 8, 2012 probably not enough port area Quote Link to comment Share on other sites More sharing options...
bassrace Posted May 8, 2012 Report Share Posted May 8, 2012 Give complete dimensions on box. Height width depth. Then repeat but with the port. Then we can help you alot more. I'm willing to bet you might have miscalculated your port area(too small) and tuning. And like said above^^^ box is rather small.
