i got 1 15 L7. its in a roughly 3 ft cubic box wit a 35hz port. i want it louder. i got it on a 1500w crunch amp and am curious if building a new box would be worth the difference? 35hz v 45hz or mayb a lil lower like 42hz or somethin?

I'd say 4.5^3 @ 38hz should be good, also look into another amp that does a bit more power, those subs can take quiet a bit of power.

it will peak higher. and give you a higher peak spl. 3.5 at 40hz should be pretty good

its probably the box,different design will most likely give you more output,at least it did for me :D

maybe you should try an aero ported box with those limited demensions if you dont have one allready

allso they say sub up port to the side works well in a trunk car unless you walled it

imo,aero's tend to turbo the bass,so to speak.lots of people like slots,from my experience,aero's are more effecient if done properly

if it was me,i would go with the sub completly on 1 side and do dual aero ports on the other,that alone would most likely give you more output.and raise tuning to 38-40.kicker subs like the high tunes lol

im kinda curious bout the aeros now lol... how do u put those into a box? obviously u would use a router to cut the hole, but what would you use to keep them in place and seal them in?

the psp aero port there are mounting holes on the bigger flange so you can screw them to the box.

like he said above. you will have to put the tubing thru the hole and put your arm thru the speaker hole to put the inner flare on, but if you only wanna spend $50 then i wouldnt do aeros. they are like $30shipped for 2

whats everyones opinion? slot port > aeros? or aeros > slot port? and im lookin to spend round $50 cuz a sheet of mdf is like $30 and carpet prices went down at the local home depot.

plus sub forward not sealed off isnt loud at all in the first place..... sub forward 1 6" pvc tuned around 34 or so to the drivers side would be much louder....

in all the cars i tested... so take my opinion lightly...but i have yet to see a LOUD trunk setup in meca that was all firing forward not seaed off. hell i havent seena setup that was loud in a trunk unless it was ridiulous like 4 15's or 4 12's.

Then you haven't went to enough shows:laugh:

My teammate Andy Mattingly did a 145.x with a single 12" Nightshade in a trunk and 148.9 with 2 of them at World Finals. He's also lazy as fawk about testing. The guy that took 2nd in my class last year hit a 150 out of Cavalier trunk with 2 10" Crossfires. It was very impressive.

I hear ya on that! I havent yet heard another single sub in my area as loud as mine, most are like "Bullsh*t thats not one twelve". with your dimensions i think you may be able to get like 3.25-3.5, a lil more than your current setup, Id also port it out the side of the box if you fold your seats down alot, I had a 00 grand am with fold-downs and it sounded great ported out the side rather than into cab, as for rattling that trunk to pieces, thats a project all on its own, just depends on the car.I was pretty impressed with minimal rattles my grand am. Heres a pic of my old box, the one im referring to.
