r.hughes Posted January 13, 2016 Report Share Posted January 13, 2016 Okay, I am building a box for four RF P1S415. I want them facing upward with a vent at bottom of enclosure. Max W is 50" Max D is 20" & H isn't a problem. I'm installing it in a 1994 Chevy Astro Van. Help! Link to comment Share on other sites More sharing options...
Joe X Posted January 14, 2016 Report Share Posted January 14, 2016 You can't place four 15 subs in a 50"x20" baffle, you can do 3 though. Also you can take out the third row or do 4 12s as above. Link to comment Share on other sites More sharing options...

r.hughes Posted January 16, 2016 Report Share Posted January 16, 2016 Joe X, you're absolutely right. It's a '94 Astro EXT also. I have enough room to put four 15's without taking the 3rd row out. My original measurements were W 50" , D 40" , H 28". Should be about 5.00 cube ft2 per chamber. 10" vent across bottom with all four 15's firing up. Please leave your suggestions.

Trentonet Posted January 19, 2016 Report Share Posted January 19, 2016 I have a 2007 hhr. Recently I bought 2 sundown e8 v4 d2. I built a box that was recommended for one and it sounds great! I see an upgrade to an Sa or x in my future.. I would like to know if anyone has built a custom box for two of them that will fit in the spare tire section in the back. I work out of it in construction and constantly have tools in there! Bad news for speakers... I've only had it in there for one day and already see problems happening ( acord end dangling in front of it makes a horrible sound during exertion) anyway I have my amps and crossovers under there it keeps them safe. A box design vented and tuned to 35 hz would be awesome to or lower. Any info I need to supply I will gladly find out. Thank you for ya'lls help in this matter...
