To fix I ordered one of these: Atrend Universal MDF Constructed Spacer for 12 Inch Sub Boxes- Adds 3/4" to Decrease Woofer Depth https://www.amazon.com/dp/B0013NWD12..._CMegBbEX0EYEH

and cut a little bit off the top of it so it would make a perfect circle with the hole I cut. Then I drilled 8 small holes and counter sunk 4 short screws in to hold this to the wall, and 4 long screws going through the ring and into the box to hold it in place. Before I had the sub mounting screws going through the helm wall and into the box. Put some silicone around all seams for good measure.

Ignore the god awful hack job hole I cut, thank god it’s hidden lol.





Other than that this thing bumps hard! This system is crazy loud, I couldn’t be happier.

And good lord those rev10s scream with 300watts per speaker!!!



Going up to the in laws lake house this weekend so I’m hoping to finish up round 1 of the rgb LED install tonight or tomorrow night.
I know you did this 2 years ago but there is a lot of good info in this thread so first of all thanks for that! On your box that you mounted to the back side of the wall for your sub, is it sitting on the floor or is it "floating"? I am wanting to do the same thing to the factory sub on my Makai but I feel like the box will be floating.
