Skullz Posted May 28, 2011 Report Share Posted May 28, 2011 A 6" aeroport 18" L will have a net of 3.45 and get you tuned to 31.39 with 8.19 per ft which is a tad small for an aero but quite doable though. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...
Bakerman Posted May 28, 2011 Author Report Share Posted May 28, 2011 A 6" aeroport 18" L will have a net of 3.45 and get you tuned to 31.39 with 8.19 per ft which is a tad small for an aero but quite doable though. Well, at 18" long, that leaves me .5" from the bottom of the box to the port, which scares me. But with two 4" ports, I got 2" of play b/w the bottom of the box and its got 11.35/ft...but the tuning is at 37.xxHZ Would that 18" long port be too long?

STEvil Posted May 29, 2011 Report Share Posted May 29, 2011 Is this in an SUV? Subs forward/port up isnt the best way to go in an SUV..

Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through. Hammerdown... 1% no links to outside websites, business related FB/YT pages allowed.

Ray Posted May 29, 2011 Report Share Posted May 29, 2011 Wont let you tune lower cause the box is to small for that much port area. Make the box bigger.

skittlesRgood Posted May 29, 2011 Report Share Posted May 29, 2011 1st of all, an 18" flared port is only 17" effective length as a port. it even says that in the description. 2nd, a small port means low output and could mean port noise. 3rd, you need as much space in front, and behind, the port as the diameter of the port. so a 4" port needs 4" clearance. you just ran into the down side of an aero port. getting a usable port area tuned low almost never works. only way to do it is an external port or a really deep box. other than a 90* bend, there isnt another way around it. If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.
