tigolbity Posted June 17, 2010 Author Report Share Posted June 17, 2010 Ok, that doesnt help me at all. I would need to make a bigger port.. its easier to use 4" pvc pipe. I still need to know what to do about CU.FT. and what to do with the port.. if i need 2 ports for 1 sub in 1 chamber, would i need more ports if i had more subs in that chamber Please help, Jeremy Quote Link to comment Share on other sites More sharing options...

Rogers Posted June 17, 2010 Report Share Posted June 17, 2010 there really is no general questions when it comes to car audio.... if people are asking for specifics, give them specifics... chances are that you will either get flamed or ignored... depending on peoples mood... but im not going to try to be a dick head here... so... pretty much double everything if you are using 2 woofers...that all i can say for a general question Quote http://www.stevemeadedesigns.com/board/topic/79921-rogers-700-dream-car-update-page-17-a-wall/?p=2335774 93 Saturn SC2My system4 SA-15's Walled 2 Cerwin-Vega S2000's 3 Kinetik Hc2000's Dual 200amp alts. you guys done with the peepee touching contest or do I need to end it?

Tek Posted June 17, 2010 Report Share Posted June 17, 2010 Tuning is based on the Dimensions of the port. Go to the12volt.com and use their tuning calculator. Just aim for about 35 hz and youll be fine Quote Link to comment Share on other sites More sharing options...

Then design and build. It's not about the number of ports, but the total port area. As a general rule of thumb, you want between 12"-16"^2 of port area per cubic foot of box volume. Instead of using pvc, why not just do one slot or square port? It would be a lil easier imo.
