Triticum Agricolam Posted October 12, 2015 Report Share Posted October 12, 2015 What are the max dimensions of your space? What kind of music do you listen to?

BoomZoom808 Posted October 13, 2015 Author Report Share Posted October 13, 2015 What are the max dimensions of your space? What kind of music do you listen to? Thanks Triticum, the max space is 36" w x 17.25" d x 15.75" h and I like to listen hip hop, country, reggae, decaf, dj snt... I have built a few boxes tuned between 33-40hz for this vehicle and have been happy with the response. The suspension on these subs is stiff so I am not too worried about playing under tuning. I have one of the 12's right now in a box that is 2.75 cubes after displacement tuned to 34hz on 1k and it has not bottomed out and it still hits the lows pretty well. I think a pair in the right box will hit pretty well. 2010 Mazda 3s 2.5L Pioneer DEH-X9600BHS Knu OFC 1/0 SS Platinum AGM / XS Power XP750 Alpine PDX F-4 / Morel Maximo 5 + Coax 5 IA 10.1 / SSA XCON 12 Link to comment Share on other sites More sharing options...
Joe X Posted October 13, 2015 Report Share Posted October 13, 2015 You don't have enough space for a 4 net box on those dimensions, you may want to see if you can get some extra space. Link to comment Share on other sites More sharing options...

Does it have to be 4 cubes? I have no idea what's recommend for this sub. Manual only gives sealed recommended specs at .9 2010 Mazda 3s 2.5L Pioneer DEH-X9600BHS Knu OFC 1/0 SS Platinum AGM / XS Power XP750 Alpine PDX F-4 / Morel Maximo 5 + Coax 5 IA 10.1 / SSA XCON 12 Link to comment Share on other sites More sharing options...
Joe X Posted October 14, 2015 Report Share Posted October 14, 2015 The sub specs are for sealed, there should be about 3 cubic feet net for the pair in a ported box. Link to comment Share on other sites More sharing options...
