Sealing trunk

[The Camry]

So I always heard that front facing a box is a bad thing but ive done it for well over a year and from my experience. You lose output but gain sound quality. Today I sealed the front correctly and wow, what a difference. Its massively changed. I lose a lot of weird upper harmonics that I was getting, ringing, and gained quite a bit output. It sounds 10x better.

Front facing if you can seal it off almost always works well. I've seen some really loud trunks that work that way and they sound pretty good too.

A front facing sealed trunk set up is essentially a small wall.

aka trunk wall which is always better than sh*t getting trapped in the trunk.

Looks good! Any more pictures of how you sealed it off? I used to have (2) 12" in a setup like this firing forward.

So essentially what I did was push the box as far forward as I could. Then took cardboard and cut out designs till I had most of the free space taken up by cardboard shapes. I transferred those to wood, carpeted them and mounted them to the box or wherever I could to make them solid. The top part was the big issue as the trunk is curved and the torsion bars get in the way of everything. I took a 1/2in mdf board and cut it the width of the box and the length of the distance between the box and trunk face. Pushed that forward and ontop of the box. Its held there be pure pressure.

I got underneath it and paint taped everything between that piece and the trunk hole. Then I used some expanding foam to fill in that top area. It should only bind to the wood so itll be removable. This also stops those pesky torque bars from rattling from bass notes.

The trick is to take your time with carboard and get that as snug as possible. A small carpeted face from the rear view and you wont even see the foam.

The back deck has been sealed/deadener/foamed a long time ago.

Great stuff expanding foam works wonders. I used a ton in my old sedan.

Just gotta be careful when and how its used. Can easily get outta hand and messy

Ive considered cutting out my back deck like you did. Nervous on what itd do to the structural integrity. I most likely will cut alittle bit out if I ever go through with plans for more subs.

Nice build. I used the cardboard cutouts to make my templates for my wood panel I cut.

Must be nice to have a perfectly square hole >.>

Cutting the rear dash you need to be careful there is reinforcement under the rear window somewhere and you can't cut that. In my civic the reinforcement was to the rear by the trunk lid so I was able to if you send me a pic of the bottom of the rear dash I could probably tell you where you could cut it but you would need to weld something in its place to reattach everything to . I was able to reuse the piece I cut out. I cut mine just to put the box in . I used at least 20 cans of expanding foam to seal the trunk. It also helps great with making rattles go away my civic rattled like crazy with subs facing back flipped to the front and sealed the trunk and squirted foam in every nook and crevice and no more rattles at all none.
