I was wondering if you could make the total back of a sub box out of plexiglass and still have good sound? Is there a better see through matieral that you could use?
Im thinking about doing something like the big saddlers setup which looks great. If I put plexiglass or something on the back, you could look through the pass through and it would look prety good. I have 2 kicker 15in comp Vr's
Also how much does a dynamat trunk kit cost at a local stereo shop?

 

Yes you could use plexiglass..... It's one of those if you have to ask you probably should not try it kinda things. Do a search on Plexiglass at Sounddomain

But if you use a clear material for a wall that large I would recommend something thicker and stronger, like polycarbonate. And have you decided how you are going to attach the sub to a thin piece of plastic?

 

i think he meant so you could see threw the back (side facing cabin) to see the speaker magnets..and also i've seen boxes made for a plexi/lexan whatever you wanna call it face ...the guy who did it f'd it up so many times though so i really wouldnt recommend trying it..i think he used 1" thick and routered the speaker placing and the outside edge

 

Plexi is acrylic. Lexan is polycarbonate. Polycarbonate is the same stuff used in bulletproof glass, eyeglasses, and many other products where strength and transparency are important. Much stronger than acrylic.
