View Full Version : Stay with Wall or back to box

08-07-2009, 11:25 PM
I was wondering what you guys think of what i should do. I have 2 Bl 18's in a wall tunned to 35hz. My best numbers with this setup has been 147.4 I'm thinking of going back to just a box and removing the wall.

This is what i have.

Can you fit 2-18s in a regular box? That score is pretty good if it's sealed up. I have a reg cab truck, which is pretty much what yours is after the wall, and it ***** sealed up. Did you ever meter it in the kick?

Box 2 12's or if it was me a single 12

how much power you got the #'s seem low...

Wow man that number seems pretty low for that setup.

Are you running sealed?

i say re build the wall better
possibly with just 1 sub

I would like to stay with this wall if possible, but I'm not sure what I would need to do to it.. This is a old build pic so you guys can see a better pic of the port area.. I know it's ugly and ruff as hell..

hmm.. have you tried port up top? how many cubes is the box and that port seems small how big is it?

Not sure if you can fit it but try one sub on top of the other on the passenger side and port on the drivers side that is the entire height of the box. But if those numbers are sealed up they aren't bad, trucks don't do too well sealed up.

try one in a 4th order

I have thought of changing subs, but still use the same wall. I want to use either 2 Fi btls or 2 Ia Death Penalty.. I know I would get the alt. upgrade before any sub changes.

there's a pair of fi's in the f/s http://www.caraudio.com/forum/showthread.php?t=425820

If I was to retune the wall, what do you think would be a good tunning level? I want to somehow make it with a removeable port. Daily would be around 30 to 32 and for spl i was thinking around 40 to 45.

port looks little small to me also, and being on the floor behind the seats i am sure affects air flow.

When I redo the front of the wall and retune it, what is the best way to build a interchangeabe port. I have not built one before..

well 1st find a size that will give you diff tunning easily and provide enuff port area and when you do that build it like this http://i668.photobucket.com/albums/vv50/DAPPA5/inter-1.jpgjust use allthread / bolts to affix it to box (screws chew up mdf after 2-3 changes
