Custom sub enclosure advice

I'm in the process of building a sealed sub enclosure for my 2013 LSV. I'm using 3/4 birch ply, and planning on coating with bedliner.

My boat has the hump that is made of fiberglass, not carpet. My plan is for the bottom of the enclosure to sit on the hump, anchored by l-brackets. It will follow the angle of the hump. I'm going to have a facade with either carpet or vinyl covering the front.

My question is, do I need a dampener (carpet or foam strips) between the bedliner of the enclosure, and the fiberglass hump? I'm just wondering if these surfaces will cause a bit of rattling. The enclosure will be several inches above the floor, so moisture shouldn't be a problem.

I'd say it can't hurt to have a damper, but the LSV I did I mounted directly to the hump with no issue.

CSM, here is what I recently did, really happy with how it turned out. I found the carpet on ebay for cheap, also worked pretty well to dampen any vibration with the footrest "hump"

Thanks, yours looks great. I'm guessing you have a little more room under there than I do because I have the same sub and I just couldn't figure out how to make the enclosure tall enough without either coming in front of the footrest or behind.

How did you attach the carpet?

I had to attach it in front of the support on the left so it does sit a bit more forward than the fascia board that was in there.

As for the carpet, I used 3M spray adhesive everywhere and stainless steel stapes behind the face.

Is this for a 2013 LSV or a 2005 LSV? Your question says 2013 but your signature says 2005.

2013... The '05 is for sale in the classifieds... just haven't updated the signature yet.

I left the carpet on my hump and I'm pretty sure the bottom of the box had carpet too. Tricky getting the 12" sub up in there. I almost thought I was going to have to remove the seat.

My biggest problem is that the distance between the top of the hump and the bottom of that bus bar only allows for an external height of 12" for my box. That's why I'm having to come down the angle of the footrest to allow more area to mount the sub.

Move your buss bar over the the inside wall if the helm, that's what I did
