candyman74 Posted November 19, 2015 Report Share Posted November 19, 2015 getting ready to start a build in a 04 Yukon for 4 sa15 d4s on a dc 5k @ .5 ohms. my question is should I build it on the smaller side say 3.25 cuft per sub @ 33hz or go a different route because of the power they will be given? if anyone has any other suggestions. guy im doing it for wants it to play really low and loud. the box I have came up with is 13 cuft after displacement tuned to 33hz with a port of 40x4.55 for 180 sqin and 21.5 length.

brent379 Posted November 19, 2015 Report Share Posted November 19, 2015 this seems like guaranteed blown woofers. granite they are very well built subs... 5k @ 1ohm is already just over double the rated rms... so a 5k @ half is asking for trouble. hope your voltage will stay in the 14s...and that you have a dd1 to set EVERYTHING cuz clipping one single time could easily blow your 15s. and smaller enclosure isnt necessarily the answer when throwing that much power over whats rated. good luck!
