thegr8cody Posted June 15, 2014 Report Share Posted June 15, 2014 My box depth is 5.5" and i plan on adding some polyfill to my box. Will polyfill behind the motor be an issue or should i put the polyfill around the sub instead of behind it? I want to make sure it can vent properly 1998 gmc sierra h/u:eclipse cd3200 sub:dd9518g d1.5 amp:jl e300/4 sub amp:dd m2a front stage:id ctx65cs dc power 270 alt lots of kicker 1/0 Link to comment Share on other sites More sharing options...
