i have a dual cab ute( 4 door pickup) ok, my system is, and im trying to set up for 80% sq and 20% spl
Eclipse avn6000 head unit (5v preout) 2 sets of kicker qs65.2 (tweeter coaxial mounted @+6db) 2x kicker cvt8.4 subs running off kicker zx700.5 1x kicker cvt12.2 sub running of kicker zx400.1
I tried the sub behind the rear seat in a sealed box (tried 15 and 22ltr) but to no luck, the sq was bad, So its now in the tray in a 64ltr ported box to kicker specs (76 x318 x555mm long port) i think 40hz going off winisd (if the volume doesn't include port volume or 36hz if it does at 79.5ltrs)
i currently have hu crossover set to +6db speakers, and sub out at 125hz, speakers on high pass at 75hz 2x 8" lowpass at 125hz (sealed @ 12ltr ea under rear seat) 12" lowpass at 60hz (64 ltr ported @ 36-40hz in tray)
As my amp has a built in subsonic filter should i re-tune the box of cvt12.2 to 25hz and set amp crossover to 50-60hz, then fit a subsonic filter to the cvt8.4 set at 60hz and crossover set to 125hz then set qs65.2 to 125hz highpass
