jeffm4688 Posted October 13, 2011 Report Share Posted October 13, 2011 I have a friend with a full size pickup who has one of the seats folded down in the back with a JL W7 on it. He has a nice sub, with a nice amp (T1500-1bdcp) but he continues to blow the sub up. At this point, its in a 4.5 cubic foot box tuned to ~32 hz with like 9.36 port area per foot. He is feeding the sub around ~1500W RMS, I know these are designed to handle somewhere around that, but AFAIK these subs will also do well on ~1000W I'm looking to design a new box for this sub, can anyone add some insight on what kind of tuning I should be looking at and around what size would be good ? I can face the port and sub up or toward the rear(currently faced toward rear). Not sure, looking for anyone who has any kind of experience on how I should able to run this sub without blowing it up again, What size box could / would anyone suggest and what size port (or port area) should I be looking at ?

cris2216 Posted October 13, 2011 Report Share Posted October 13, 2011 i think 4.5 cubic ft is too big for that much power i would do 2-3 cubic ft box tuned to 30-35hz and more port area instead of 9 per cube do like 12 Quote Link to comment Share on other sites More sharing options...
CleanSierra Posted October 13, 2011 Report Share Posted October 13, 2011 Too much air...not enough port....too much power. Quote Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...
jeffm4688 Posted October 13, 2011 Author Report Share Posted October 13, 2011 (edited) i think 4.5 cubic ft is too big for that much power i would do 2-3 cubic ft box tuned to 30-35hz and more port area instead of 9 per cube do like 12 Ok, I was actually thinking the same thing, I was thinking 3-3.5 cubic foot though tuned to around 31 though. If I was looking to feed it less power, more around 1000W RMS, what do you think I should be looking at size and port wise ? Edited October 13, 2011 by jeffm4688 Quote Team L.I.

cris2216 Posted October 13, 2011 Report Share Posted October 13, 2011 ithink 3 cubic ft for 1000 w is perfect and portwise about 12-13 per cube tuned to 31hz Quote Link to comment Share on other sites More sharing options...
