I'm looking to make another enclosure for my Type- R's. I currently Have 2- 10" Alpine Type-Rs in a sealed box. Approx .7ft3 per sub. I'm running these subs on a Hifonics BRZ2400.1d wired in 1-ohm configuration. Looking to put them in a ported box. This will be going in a 2011 Aveo hatchback. I'm thinking subs up, port up. I'm looking at 3.53ft3. Dimensions of the box will be: 27W*18H*16L 2- 3" round ports 5.5"L Tuning freq comes to 35.67Hz port disp .05ft3 net vol 3.48ft3 gross vol 3.53ft3 port area range 31-45in2 port area- 7.07 in2 port area per ft- 2.03in2 This will be about the best configuration for me, as I will not have to move the amplifier. I currently have the sealed box and amp mounted on a sheet of mdf in the hatch now. I can roll the seats forward and access the spare tire easily with the current setup, and wish to maintain that ability with these subs. Please double check my math, and let me know if this setup is worth building, or if I should leave the setup in the box it's in.

I've got 2 12's (1242d) and am probably going to build a ported box for them. I was just curious if anyone has ever had them in a sealed box, and how they sounded. Or if anyone has had them in a ported box, how they performed.

Hi all I have just bought two 12 Alpine type r 12d2s 1000 RMS each. I am looking to put them in ported enclosure but need help on what size to use. I'm looking for deep loud and low bass with the best frequency respose possible. I am able to fit a 4 cubic foot box in my trunk after port displacement and sub displacement. Also if I tune to say 32hz will I get enough bass upwards of 45hz or will it start to roll of/ Also what size port should I use I was thinking 3 inch wide 12 high does port size affect frequency response such as making the response shorter or longer. Hope some one can be of assistance
