c_naisbitt Posted July 17, 2013 Author Report Share Posted July 17, 2013 I would like to build one that will come out when the seat goes back in. When the seat goes in I have enough room to make a box on either side of the tranny hump. Im just trying to figure out how to make a box both now and later. Caise if it isnt possible to make a 1 cubic ft box tuned like that ill go back to the drawing board. I dont mimd having a temp box until I put the seat in and can measure what those dimensions are.

Hellbilly429 Posted July 17, 2013 Report Share Posted July 17, 2013 Ah, ok, was very confused, lol I am thinking 2 full length (17") 4" aeroports will get you to 34hz if you double the baffle Problem is the small space makes it hard to tune that low without sacrificing port area. Aeroports are more efficient and don't require as much port area to produce the same effect as a slot port, so the amount of airspace from 2 4" aero's should be plenty sufficient for airspace 2018 Honda Civic Sport Hatchback (build in progress) NVX Sound Deadener (Front Doors) Stinger FAST Rings Stock Electrical SSA Evil 6.5's Front Speakers Stock rear speakers MB Quart ONX4.80 speaker amp Rockford Fosgate T-1500bdcp DC Level 4 12" D1 @ 2-ohm Box In Design Stage Stock RadioMy Build Log Link to comment Share on other sites More sharing options...

c_naisbitt Posted July 17, 2013 Author Report Share Posted July 17, 2013 I hadnt tried doing more than one port. Yeah ive definatly come to find that smaller air space is alot harder to tune that low. When I throw the seat in I think I man do a common chamber over the tranny hump to maby make it easier to get more air space from it. Think thatd make it any easier?? Anf thank you for the help! Much appreciated. Link to comment Share on other sites More sharing options...

Hellbilly429 Posted July 17, 2013 Report Share Posted July 17, 2013 Yes, common chamber will give you much better results and easier to tune Here is a great thread that Rusty actually just did, 4 m3 8's in a silverado. Also shows some of his over the tranny hump fabrication to give you a good idea http://www.stevemeadedesigns.com/board/topic/171340-4-dc-m3-8-inch-subs-in-my-silverado-build-over-the-weekend/ 2018 Honda Civic Sport Hatchback (build in progress) NVX Sound Deadener (Front Doors) Stinger FAST Rings Stock Electrical SSA Evil 6.5's Front Speakers Stock rear speakers MB Quart ONX4.80 speaker amp Rockford Fosgate T-1500bdcp DC Level 4 12" D1 @ 2-ohm Box In Design Stage Stock RadioMy Build Log Link to comment Share on other sites More sharing options...
