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 -
I have never build a 4th order box and want to give it a shot. So any advice would be great. I have 2 Sundown zv4 15s D2 custom build for 2k rms each, wired to .5 ohm. I am wanting to do a C pillar build in my 97 4 door Blazer. This is currently on a BC3500 and later looking to get another one to push at 1 ohm a piece. My question is on the sealed side what would be the best sealed cubes. I was thinking of doing 4 cubes for both subs and 8 cubes ported and tuned to 40hz. Does this sound about right for 15s on both the sealed and ported? and is tuning it to 40hz good or should a do 45hz. I love the low lows. Thanks in advance. 97 S10 Blazer (4 Door) 4.3L 2 - Sundown Zv4 15s D2 custom built 2k rms each wired to .5ohm Crescendo BC3500.1 300 Amp Alt 3 - Group 31 AGM batteries
