Hey guys i was lucky enough to aquire a 1 inch sheet of plexi. after some previous posts i have decieded to turn ma subs around and use a plexiglass back . I have made the box out of 1 inch MDF and sandwhiched this 1 inch plexi glass in the back cutting grooves in the wood so it sits flush at the back. any way a couple of questions and thoughts please How do i secure this plexi to the back what is the best product I am not too worried about the end result on the join as i am getting decals for the plexi to round off the edges and blend to the fabrication on the rest of my boot. I am thinking of fibre glassing the inside to add a little effect but most of all to act as a bit of a deadener and sealant of the box. can i just use fibre glass resin and coat the inside or should i use some matt as well on the inside. I was thinking Dynamat but it will make inside look tacky as visual inside the box will be high. this also might help I am running two pioneer TSW3004SPL. 3000 wat (1000 rms)DVC 4 ohm subs. I have two amplifiers both Pioneer 800 watt monoblocks (GMT-7100) i have them currently wired up amp to sub then jus linking the two coils. advice would be good thanks

Do you have any pictures of the box? If I understand correctly you are invert mounting the subs to the plexi side of the box which is facing the opening of your trunk? If screws won't work with the design I would use some high strength silicone.

One product i like that always worked well for looks is just some texture paint in a spray can. You can get it in many colors to fit the rest of the install and looks really nice as a finished product for the inside of the box. As for sealing the plexi glass. Some F-26 or liquid nail i bet would work really well. Just dont ever plan on getting the glass off after it sets if you use it. -------------

For sound deadening I would suggest using some 1/2" thick foam pads and paste them on all of the sections that are wood. When cut nicely, you probably won't notice that it's in there. This would probably be your best option for dampening the back wave of your subs without fiberfilling the box. You could also paint it to match a color scheme. partsexpress has a good selection of foam pads, but I'm sure you could find it at a number of places. For a different look you could also use the egg crate stuff... just a thought. ------------- -Dual XHD6425 - HD Radio w/USB & 3.5mm in

I have not personally used egg crate foam but I would imagine it would dampen a little better than the flat foam. The only downside is the more obtrusive look, but that could be an upside depending on what look you are going for.

Egg crate foam, is used primarily to deaden reverb and acoustic echo, as well as dampen sound, but i seriously don't think it good to use IN a speaker box for the above said reasons. Egg crate foam might actually kill sound you're looking for, i suggest using the egg crate if at all AROUND the box, or perhaps in replace of dyna-mat...
Just my 2cents

Also, i build custom fish tanks and have some experience with PETG /Plexi/ Acrylic, etc.. and adhereing said materials to wood can sometimes be tricky.
1 was i would suggest, if to drill pilot holes into the plexi and wood, and use flush mounting screws to anchor it down, and with the application of a high density silicone in between wood and plexi.
2 silicone plexi down, and build thin wood housing around plexi to sorta sheath and mount...almost like a tongue/groove joint.

the box looks really nice good job on it. just something for you to think about for your next plex project. i usualy attach the plex to a flat surface instead of flushing it in by notching into the box, then make a trim plate(beauty board) around the box to cover screws and showcase the finished product. usually use some type of foamy material(some times carpet works well) to seal the plex in, since using silicone will not allow for removal and repair work if it's ever needed. if you do deciede to go with silicone make sure you apply the silicone to the box then allow it to dry completly(24 hours+) before you attach the plex to it. good luck on your project ------------- life is a comedy to think, a tragedy to feel
