Saltine Posted February 22, 2012 Report Share Posted February 22, 2012 ok, been a while since I posted here. built a custom box in my 95 fleetwood trunk for 2 original loaded 18" Fi BL"s...I wont lie im not even sure of if its big enough, FI wants 5cubic foot per sub so hopefully its 10 cubic foot or close, I just went at it. its prolly 10 cubic foot anyway I need to be tuned around 33hz. I can definetly fit a 4" aeroport between the subs at the top of the box, how long does it have to be 12-16" per cubic foot 120-160 square inches i know this isnt the best scenario just get close. still being built Quote Link to comment Share on other sites More sharing options...

SnowDrifter Posted February 23, 2012 Report Share Posted February 23, 2012 You are going to want more than a single 4 inch aeroport for those subs And FYI - the 12-16 sqin per cube is pretty much BS and should be used a reference only. It is based on how much power you are throwing at it (total air displacement of the subs), and tuning point. I've had 11 sqin/cube sound perfect and 18 sqin/cube chuff and be a leaf blower. It's really install dependant.

Saltine Posted February 23, 2012 Author Report Share Posted February 23, 2012 theres more screws behind the front baffle too and wood glue and fiberglass resin I can fit another port on the bottom of the front baffle between the subs so say 2 4" ports tuned to 33hz, box is 10 cubic foot, just an estimate to see what i can fit here...cuz of the floor i can do a long port on the bottom unless i bend it and power I have the 1st model sundown 1500 amps. 1 per sub at .5ohms Quote Link to comment Share on other sites More sharing options...
SnowDrifter Posted February 23, 2012 Report Share Posted February 23, 2012 Is there any way you could fit 6 inch ports? Maybe tune a bit higher?

412 CVX Posted February 23, 2012 Report Share Posted February 23, 2012 was this originally going to be sealed? unless i'm missing something, there's no way in hell that box is 10 cubes. i hate to be captain hindsight, but you really should have had the design part thought out before you started building. two 4 inch ports wouldn't be near enough port area. for 2 18's. or even 15's for that matter. sorry there's not a hell of a lot that can be done at this point Quote Just say no to Ground Pounder Customs. My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.

bumonskateboard6 Posted February 23, 2012 Report Share Posted February 23, 2012 What are the dimensions on your box?

Low voltage doesn't blow amps. That's a myth. A router that does the sub holes makes rounded edges also? Link to comment Share on other sites More sharing options...
