Brahma Owners (or ex-owners)

I'm gonna recone my 12's to 15's (have 2 of them). Just wondering what type of enclosures I can play with. It will be going in an '01 Accord and I can do approx 5.5 cubes net (this is the largest I can go with the additional items in my trunk).

First question: For ported, how much space would I need?

Second question: For sealed, how much space would I need?

Also, I am not looking to compete. This will be used for daily driving, I'm wanting to get fairly loud though. I have an RF T30001bd to play with so power is no issue.

3.5 - 4 cubes tuned to 28-32 Hz

2 - 2.5 cubes sealed

i remember running my 15 brahma in a 3cuft @ 28hz. great low end. and I believe sealed should be around ~2cuft.

they were mkIIs.

edit: ^^^those are good recommendations too

I would suggest you go sealed for both of them.

3.5 - 4 cubes tuned to 28-32 Hz2 - 2.5 cubes sealed

would that be per chamber or total for both?

why sealed over ported? just curious? i have a 12" mkii at hand right now, the mki is at a friends house. i have two sealed enclosures to work with and a ported to test out, which hopefully ill get to today if i can finish installing my additional battery and processor.

i'm suggesting sealed because i don't think you have enough space for both ported. and the specs about is for one single 15"

Ported would sure be nice, but I have been pleased with sealed. Just curious, does enclosure size vary with the power it receives? Reason I ask is becaue of the following PDF:

I've ran PLENTY of different brahma's and for your accord (with the power you have), go sealed! You don't have nearly enough space for them ported. I've done 1 sealed, 1 ported, 2 sealed and 2 ported.... Had 2 ported with 2 cubes of airspace each (I know, WAY to small) and the 2 sealed (same power) at 2.5 cubes each was WAY louder AND lower...not even close. Did 2 ported right, same power, 3.8 cubes each and that slaughtered the 2 sealed!!! But with your space, I'd def. do 2 sealed. They'll get MORE than loud enough for daily driving!
