This is what we came up with. Screwed a hook into the ceiling and racket strapped aroun the motor to hold the sub in place.
The fvcked up thing is these subs didn't fit my 18 holes. The spokes wouldn't clear. Now my holes arnt perfect cuz I cuz them with a jig saw but we even tryed to spin the sub and it just wouldn't mount flat.My crossfire xs v2 fit great. And so did the sundown SA 18s and those had the same baskets as thes nsv3 I thought but there just a bit to big.. So now one of these days I gotta trim my holes up so they fit and try this again.
