duct_tape123 Posted July 12, 2007 Report Share Posted July 12, 2007 Well I built a ported box for some old rockfords that I had lyin around. My first ported box! Some songs it sounds good(Fresh Azimiz- Bow Wow) but others it hits WAY to high and its pissing me off! Using 3/4" MDF outside dimensions are 45" X 15" X 15". Two seperate boxes with the divider at 22.5" on center. One slot port 6.25" X 2" X 10.75" per side. Is this right for these subs? Need 2.0 cu.ft. per sub.

duct_tape123 Posted July 12, 2007 Author Report Share Posted July 12, 2007 Thanks guys! What should the port size be / per chamber? Its going in a 1999 suburban if that helps. I want it tuned for ground pounding but dont know what to do with the ports. Thanks, Chris Link to comment Share on other sites More sharing options...
