Getting ready to start a flush mounted 12" single sub box in the trunk. The idea is to remove the rear floor of the trunk and use the storage compartment thing where other cars usually have a spare tire, under the trunk floor lid for my sub magnet to sit inside.
My thoughts are to fiberglass the trunk floor and use wood for the sides and top platform. The box will probably extend the floor height up about 1.5-2" above where the trunk floor is in order to give the sub magnet some room. The subwoofer hole will be routered and sub will mount below the surface so that a grill will sit flush with the top of the box/new floor. The box will be recessed about a foot from the rear seat so I can mount my amps there and place a peice of plexiglass over them so the floor is completely flush.

Has anyone seen any boxes like this premade or a flush mount trunk box like this? I checked with my shop and the builder quoted me $300. I'm going to try it myself first but wanted to see if there is anything already premade for cheaper. I havent had much experience with fiberglass but cant be too tough. any recomendations for stuff that works like fiberglass and is easy to use
Thanks for input

 

The goal is to get some trunk space back where my subwoofer currently is and taking up too much room. I've got a new baby and trying to get the stroller and all that shit in is a challenge with the box I have now.

I've seen the kicker boxes and ones that fit on the sides of the trunk space but I'm looking for something a little more custom and less of a footprint in the trunk

Might be what you are looking for.

 

That's exactly what imntalking about but with a jku. Thank you!! ,

 

I have a 4 door we took two 10s and put them in box 8 in tall and just built a platform right over the top...subs fire down my buddy's fire up and they suck with the top off..something to think about? Also watched cartoys take 2 two 8s and install them firing down in the tool box with a 3rd 8in aftermarket in the factory housing it was pretty sweet

 

A friend fiberglassed his tub and put two 8's, now we're doing mine with a shallow mount 12" Fosgate. Space ends up being right at 1 cu ft or .5 on each side if you split it, so make sure to get a speaker or speakers with those specs. Mounted amp under rear seat hidden away. Fiberglass mats and resin were about $30 at Walmart.

 

Here is the fiberglass and amp

 

Looks good I may do that instead. What year is ur jeep? It looks like ur seat cushion folds up. I don't thing my 07 Sahara does that. The seat back just folds forward

 

It's a 13. Seat doesn't fold up, I unbolted it to mount the amp.

 

Have to clean it up, but it turned out great!
