Beamerguy Posted August 14, 2017 Report Share Posted August 14, 2017 BRAND OF SUBWOOFER: SUNDOWN MODEL: SA-12 IMPEDANCE : DUAL 4ohm RMS RATING: 750 RMS Looked at Sundowns website but there box is a little too big for my trunk. Area I’m working with is H-16 W-35 D-38. Running them off a Sundown 1500 Watt amp. The tuning id like to go for is 32HZ Link to comment Share on other sites More sharing options...
ckeeler11 Posted August 14, 2017 Report Share Posted August 14, 2017 Can do 16" H x 35" W x 24" D with a port of 14.5" tall x 5" wide x 36" long. This will give a tune of 32 Hz and volume of around 4.15 after displacements. Link to comment Share on other sites More sharing options...
Joe X Posted August 16, 2017 Report Share Posted August 16, 2017 So here is a suggestion, power: to subs rated, amp subsonic filter to 28Hz, minimum port clearance 4 1/2", figure is just an assembly guide: NOTE: If building outside you need to build a cardboard dummy box to test fit in it's way inside.
