DodgerCannon Posted July 20, 2011 Report Share Posted July 20, 2011 Hi all, I'm rebuilding my wall soon, Im thinking about doing a drivers side port tuned to around 28hz. Kit will be level 5 18s, 6k. What box volume and port area would you suggest for a flat wall with drivers side port? I've used them in 5.5cuft each but if I can gain more output with volume I will do it, as long as it retains a flatish response. Cheers dudes.

6berry Posted July 21, 2011 Report Share Posted July 21, 2011 DC recommends 6 cubes per sub but since youre giving the subs less power than they can handle i think you should be able to make them a little bigger than 6 cubes and youll get more output Quote 1999 Audi A4 1.8T::: 4 - DC Level 3 10's in a 4th order Rockford P6002 on Subs for now (3-3.5k coming eventually) MB Quart ONX4.60 for Mids and Highs Boston S50 Components in Front Boston S65 Coaxials in Rear 40 Sq Ft of Second Skin Damplifier Build Thread UBL 1948 Plymouth Link to comment Share on other sites More sharing options...
DodgerCannon Posted July 21, 2011 Author Report Share Posted July 21, 2011 They are getting 3k+ each so over the rated power handling. I think ill be able to give them 7cube each...anyone think that's too big? Quote Link to comment Share on other sites More sharing options...

DodgerCannon Posted July 23, 2011 Author Report Share Posted July 23, 2011 (edited) The testing format I compete in is called propper droppers, we test at the head rest at 40hz, 33hz, 25hz, 20hz and a peak... the scores are them averaged out to give a final score. I've used 35hz tuning with 18sq" and my average score was 151.5 (peak 154.9), I then blocked up half the port area 9sq" tuned to 25hz and averaged a 152.5 (155.2 peak) and all my other scores rose too. I know you guys always tune mid to high 30s with massive ports but I haven't had good results with it, as I say I've had better results from using 9sq" per cube with uber low tuning.... and it sounded better, tighter, shifted more air, smoother. I think I'm gonna use 10-14sq" next. The car is a vw lupo, tiny car . Edited July 23, 2011 by DodgerCannon Quote Link to comment Share on other sites More sharing options...
