quest for 140

[Purplehaze]

Well, I put my 12's in 5 cubes @35hz, and got a 141.1 this past weekend. And I'm runnin' cheap subs. So you should have no problems.

Need more port for sure. Coming from someone who has done a 150 + out of a trunk do 16-18 sq inches of port per cube if using aeroports and if doing a slot port do 18-20 sq inches per cube.

I´ve always said it, that 12-16SQ of slot and 8-12SQ of aeroport rule is dumb lol

I have 2 6" aeroports right now for a 3.25 cubed box after all displacement. Sub up port to the side in my trunk. Single 15 on a AP 1500 and stock head unit (less than 1 volt going through my rca's) doing a 145+ on the TL.

Port area is key to good numbers.

151.8 for me with 2 12´s on a 3 cubic feet box and 2 6" aeros, that´s 18.66SQ per cubic feet of aeros and yes, it sounded great on music, i´m not gonna lie to you, it was kind of peaky because of the port size, but was nasty as hell.

ya but wont more port make me tune lower in the same box?

More port means you need even more lenght to tune it lower.

Hommie trust me, getting to 140 isn´t hard, i don´t know much about those subs, but a regular daily box that sounds good on almost every pair of 12´s would be something like 4 cubic feet and 60SQ of slot port, maybe you could use a pair of 6" aeros or 3 4" aeros, i can asure you, that should score a 140 without any problems...

i was gona use the 6" aeros parts express has but there od is to big for my boxes width with the subs in it wont fit

my max dementions are 16h 33w 20d in inches. i dont think i can fit 60 sq" of port and keep the box 4 cubes everytime i try i get down to a little over 2 cubes

you can always go with subs back/ports side hommie, that works great on a lot of trunk cars,BUT, if you wanna go with everything forward sealed of the trunk then that should be louder.

Said that, i understand you, 6" aeros can´t fit there unless they arent flush mounted wich you can try, or just stick with a nice slot port; With those measures, i´m sure you can go with a port 14.5" H x 4" W x 23" D on a L shape port, that would give you a very nice port area with a 37 hz tuning and around 1.9 cubic feet per sub after all displacements, that should work!
