slinky8733 Posted February 14, 2008 Report Share Posted February 14, 2008 I have 2 FI btl 18's and four kicker kx 2500.1's and i need some help on a box for them! I have a quad cab dodge. The back seat is out and i have 60w x 27h x 26d. i have one in there right know and the box is firing to the windsheild and it beats. Its doing a 149.8 on the dash and a 150.3 in the kick. I had the box firing to the roof and it didnt sound as good and didnt beat as hard. So im looking for some help. This is really bothering me and im ready to start on this box. please i need all the ideas that are out there! thanks slinky8733 Link to comment Share on other sites More sharing options...

REVOK1NER Posted February 14, 2008 Report Share Posted February 14, 2008 Do both subs firing towards the window and put the port on the drivers side to build up pressure for the mic on the passenger side? I think that sounds right, also tune low since they are BTLs. 2000 Ford Explorer XLT -20" RVM "Buck" Wheels -2.5% Tint -CompuStar Vizion Alarm -(4) Infinity Kappa 680.7cs 5x7" -1 XStatic BatCap Model 300 -2 18" DC LVL 4's -Amps are undecided Link to comment Share on other sites More sharing options...
