DBz Posted May 19, 2011 Report Share Posted May 19, 2011 Ok, so originally I wanted to do 4 15s in a wall, but after building the box and after bracing displacements, i'm at about 10-11 cubes. The "Vas" of these subs is 141 liters (4.9 cubic feet) , so should I just do 2 15s @ 10 cubes? (5 ft each?) thanks (2) Kicker L5 12's Alpine IDA-X305 HU Dual Optimas Big three Kenwood EQ RF Components Hifonics Brutus 1K (Subs) Alpine MRP 250 (Mids/Highs) Lots o' sound deadening Link to comment Share on other sites More sharing options...

Supercharged DCs Posted May 19, 2011 Report Share Posted May 19, 2011 2 15s in a good enclosure will sound better than 4 15s in a bad enclosure. You don't have space for 4 properly, so do 2. Bassless once again. Can't seem to keep a system for more than a few weeks Saving for a '06 Nissan 350z, look for build around June 2012. Link to comment Share on other sites More sharing options...

Supercharged DCs Posted May 19, 2011 Report Share Posted May 19, 2011 I wouldn't give them less than 3.75 cubes each, which multiplied by 3 is 11.25ft^3. He mentions he only has between 10-11cubes (he should really figure out which one it is lol...) Bassless once again.

DBz Posted May 19, 2011 Author Report Share Posted May 19, 2011 what kinda car is this in? what subs? how much power? Rockford Fosgate P3 15s (Dual 2s) 97 Honda civic, I had it on the TL and its resonance frequency of the car is @ 42hz. So would I be okay having a slot port down the middle tuned to 38 hz? sorry and i just measured again its 10.5 cubes after displacements (subs and bracing). im going to be running a Hifonics Brutus 1000 watt @ 2 ohms so i'm guessing somewhere around 400-425 per sub.
