View Full Version : Best configuration for box

08-25-2008, 10:46 PM
alright i have a supercrew f150 and after 2 ok loud systems ive decided i wanna take the rear seat out and build a monster. Itll be two mj18 (or any other good match for a sundown 1500) in anything less than 15 cubes. I was wondering if it would be best to sub up/port up or sub up/ port forward config? also,what tuning would yall recommend. Listen to mostly southern rap, and chopped and screwed.Lastly, how much space would you give each on? like i said i can fit up to 15 cubes so ya.

Thank so much for your input!

i would do sub forward port up or both sub up port up

i also listen to alot of southern rap and although my box is tuned to 32hz(little bit too low) i find the 34-38hz to be best frequencies to tune for this music
