Lith Posted January 26, 2010 Report Share Posted January 26, 2010 if you wanna use the recommended box size for these, and you want to have it ported than you will need to have a bigger box than 7 cu ft... 8x1.5=12 idk if im right or wrong but thats what im saying.

Playa Named Joe Posted January 26, 2010 Report Share Posted January 26, 2010 I wouldn't go any smaller then 8 cubes on the box, I would probably make the box around 12 cubes if you have the room. 1994 Pontiac Grand Prix build Link to comment Share on other sites More sharing options...
scfaust Posted January 27, 2010 Author Report Share Posted January 27, 2010 i thought the smaller the better power handleing http://i720.photobucket.com/albums/ww203/scfaust1/alphadamp.png Link to comment Share on other sites More sharing options...
STEvil Posted January 27, 2010 Report Share Posted January 27, 2010 Could go small if you made a huge port like what you see in T-Line setups... and flare the end like a horn MickyMcD - "Capable of making some serious trouser flapping volumes at where's-my-testicles frequencies, the Servo-Drives used to be fairly jaw dropping..." Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through. Hammerdown... 1% no links to outside websites, business related FB/YT pages allowed.

Torres Posted January 27, 2010 Report Share Posted January 27, 2010 i thought the smaller the better power handleing to an extent. you just cant make the box as small as you can or want. the subs still need air to breathe Link to comment Share on other sites More sharing options...
