Zendejas Posted March 31, 2015 Report Share Posted March 31, 2015 Long time reader First time Poster.I have a 2010 Altima Currently have 2 Alpine Type R 12's. Was in a rush so bought a ported box. Bass sounds off so would like a custom cox. What would be the best specs for a box. Box Builder need Central California Area. Link to comment Share on other sites More sharing options...
Shenker Posted April 1, 2015 Report Share Posted April 1, 2015 cant build one for you but the 12s sound best around 2 cubes per woofer, 14-15 port area/cube, ported around 35-37hz at rated power (1000w), and they will do pretty good, im a big fan of type r's myself. Here's a link to one I built for 2 12s last fall, port area was a little low but it never choked it off, just could have been more. it was tuned at 32 however, it sounded great! -If its loud, fast, outrageous, or all of the above, chances are i'll think its awesome. -"No way he's OCD." -said none of the people that know me ever. 04' Suburban "Lucifer" A.K.A #Lucii (Under Construction) 4 10s on 4kW in 6cu net @~28hz /////Alpine Crescendo KnuKoncepts Optima SHCA Build Thread 92' JDM 325i "Stella" ~Going for sale to build a 350+hp E30~ Gutted pipes 96,000 OG KM's (59,000 mi) -System Removed- 1 10 on 1kW 89' Gen 3 Honda Prelude SI AWS "Odis" Bone Stock Possibly going to stance it Link to comment Share on other sites More sharing options...
Joe X Posted April 1, 2015 Report Share Posted April 1, 2015 Here is one spec for two current generation SWR-12D4 Alpine type Rs, subs/ port forwards / backwards, need to verify dimensions are good for your vehicle, power: to sub(s) rated, amp subsonic filter to 28Hz, minimum port clearance 4 1/4", figure is just an assembly guide:NOTE: If building outside you need to build a cardboard dummy box to test fit in it's way inside.
