budah93 Posted July 21, 2012 Report Share Posted July 21, 2012 I have 2 sundown audio sa-15s d4s running on a hifonics hfi1500 in a 1998 gmc jimmy 4 doof. I think that the subs should be louder just judging by what others are saying. Here are the dimensions and port area of my box. 16h 36.25w 24d with 90 sqin of port area and its tuned at 35hz. I'm getting the big 3 and sound deadener put in next weekend so i was wondering what else i could do to make it louder. it's not a spl vehicle but i still think it should me louder. The usable room that i have to increase the box size is 21h 36.5w 28d because i like to have backseats and really don't want wall. Any advice would be greatly appreciated Quote Link to comment Share on other sites More sharing options...
Ddub847 Posted July 21, 2012 Report Share Posted July 21, 2012 what size is your port because i think your box maybe be a little small Quote Link to comment Share on other sites More sharing options...
budah93 Posted July 21, 2012 Author Report Share Posted July 21, 2012 the demensions of it are 15h 6w 23d to the very back of the box and 13.5 to wear the sides of the port end if that makes any sense at all Quote Link to comment Share on other sites More sharing options...
Ddub847 Posted July 21, 2012 Report Share Posted July 21, 2012 your tuned @ almost 43 hz. which is high for a daily box. 2nd your box is under 4 cubes which is small Quote Link to comment Share on other sites More sharing options...

Ddub847 Posted July 21, 2012 Report Share Posted July 21, 2012 you have a really small box. Gross your box is ok but your port takes up a good portion of it Quote Link to comment Share on other sites More sharing options...
