Post Number: 442 Registered: Dec-06 | the website says it likes 1.8-2.5 cubic feet the vent will prob take up .7 and the sub will take .15 so the total will be about 1.85 how much power u giving the sub? also sence you dont have much box volume to work with i would recommend using aeroports becuase they take up a lot less room |

Silver Member Username: Liqdfire3Lee high acres, Florida Post Number: 106 Registered: Sep-05 | im going to be giving the sub at least 1000 rms. probably a hifonics 1206 amp. what are aeroports? sorry im not familiar with these. but i wanted to go with the vented because i could just have the port on the front center. |

Here is a link to where you can buy some. http://www.psp-inc.com/ http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=268-352 |
