those hds3s like a big box, build a custom box do 5 .5 cubes net tuned at 32 and you'll be good

So here is a suggestion, power: to subs rated, amp subsonic filter to 28Hz, minimum port clearance 5 3/4", figure is just an assembly guide:

oh shit, Joe x helped you out I see. he helped me on mine for my 4 15s cvrs and it came out good. hit a 146.3 sealed on music, with voltage drop to the high 10s and 11s, so it could have been way louder. that same box now holds my 2 18s which sound louder than the previous setup. my advice is take his blueprint and get building.. you wont be disappointed

yep yep waiting for the subs and amp and wiring all to come in then ima get the box built in the mean time. will post once its done thanks guys
