the_village_idiot Posted December 24, 2017 Report Share Posted December 24, 2017 So i got a hand me down sub a couple days ago (my buddy upgraded to a sa12) and decided to build a box for all three lol. So now i have 2 batteries, one 140a gm alternator, one stock 90a alternator, big three, 1/0g wire, 3 pa gothic 12s wired at 2.6ohms, a hifonics bre2500.1d (yes, i know its junk), and a box that i designed and built at 7.6cft, tuned at 33htz with 13.8sqin of port area per foot. It has a triple baffle, and 2 center supports of 3" dowel rod. All in the rear trunk space of my 95 jeep xj. Just making this post for the hell of it. I think it turnout out pretty good. So, how does it look? Its my second attempt so go easy on me lol This was the result lol A short Little video lol Link to comment Share on other sites More sharing options...

8ten8 Posted December 24, 2017 Report Share Posted December 24, 2017 Looks like they line-up right. Nice work! What's your voltage like now? Sub up port back, I'll take the kids. Lol Link to comment Share on other sites More sharing options...
the_village_idiot Posted December 24, 2017 Author Report Share Posted December 24, 2017 the voltage is dipping to 13.9 but thats not too bad. Thats under extreme bass for a really long time lol Link to comment Share on other sites More sharing options...
Wishuponasub Posted December 24, 2017 Report Share Posted December 24, 2017 Not bad..... Lmao. People would kill to hold 13.9 Sitting around waiting to be installed: 4 FI X 10 270 CES alt D3400/73ah lithium AA 3800.1 (2) AA 75.4 Link to comment Share on other sites More sharing options...
Joe X Posted December 24, 2017 Report Share Posted December 24, 2017 Based on your specs port area seems fine and the box looks pretty well built, now doing 4 subs subs up / port back would let you run your amp at one ohm and you would get more out of it, of course some improvements in your electrical would be needed. The combined effects of increased cone area and reduced final load impedance would surely get you louder. Link to comment Share on other sites More sharing options...
anr102990 Posted December 24, 2017 Report Share Posted December 24, 2017 box looks great to me man. Hard to tell by a video like that but they seem to be getting down pretty well for what they are! Best of luck. Link to comment Share on other sites More sharing options...
