Default plexigalss and mirrors

i am getting ready to build a new box for my 12w7 and i really want to do a plexigalss and mirror enclosure. where do i get 3/4" plex and do i need to get special thick mirrors for the inside of a enclosure. i am sure that a thin mirror would be subject to breakage in a sub box let alone in the car inviroment. i want the mirrors because there is no need for more than 1 12w7 and the mirrors make it look like there are many subs. i also want to show off the back of the sub since i paid so much for it. it just looks awesome and it is a shame to hide it. any ideas?

Maybe make a V shape of mirrors behind it? Make sure you don't break mirrors i'm sure the w7 can.

Maye you could put a mirrored tint on plexiglass. Im almost sure ay mirror would break with that sub. Or you could put some really thinck sound deadening around the mirror

Plexiglass emitts gasses and causes tiny air bubbles to form if tinted. There is a product called mirrored plexi glass that has a baked on finish, search the web. Tintdude.com comes to mind?

I can help you out on this one!!!
Here'* my box for 2 10 W7'*



Trim plate being made


For W7'* you should use 1in. MDF, don't use the standard 3/4.

For the Plexi it was ordered out of a glass shop, think mine is 1in and cost around $120 for the sheet, there was cheepier and lots more expensive plexi out there. You need to tap the holes in it, don't want the plexi to split or crack when the final screws go in.

For the mirror, mine is Plexi mirror, I bought it a Home Depot for $25ish. Big sheet too, enough for whole box and my deck lid too. This stuff is very easy to cut, WARNING also VERY EASY to scratch, even paper towel will scratch it, only use proprer towels.

Hope that helps, lots more pics of my install here http://www.cardomain.com/memberpage/395342/3

oh, enjoy the 12w7, I know you will. what amp you running it with?

Well taylorD this was pretty much directed towards you because i knew that is what you had. So you used plexi mirror not real mirrors? i have never heard of that. how big is a sheet of the 1" plexi. i do not need a 4'x8' sheet as you know. any other tips you have would be greatly appreciated. I truely am not trying to copy your car but you sure do have the same ideas that i have. just curious if you have mounted your front speakers to the doors yet or if you still have them mounted to the door panel?

Correct, it'* easy to work with too, but again sctaches easy.

For tips use 1in MDF, not sure on my plexi sheet size but my box is around 34 long 16 deep and 15 tall, close enough, Funny I've never measured it, It was built to JL
* recomend specs for 1 10w7 than X2.

Leave the protective sheet on the box as long as you can, don't scratch it, you'll be pissed. Also paint the inside of the box white, will help the brightness of the mirror since it is just plexi coated mirror finish.

Any other questions,

Pic with film still on and box already made and taped and drilled sealed. Oh, you are going to use some kind of sealant/glue when the screw the box together, make sure there'* no leaks.

what did you use to cut the plexi glass and the plexi mirrors. Also you have a sealed enclosure and i currently have a ported box. have you had you subs in the ported box or did you go straight to the sealed box they are in now. i was just wondering because jl audio says that the ported box is 3db louder then the sealed box and was worried that it will be a drastic change. this is my first ported box and i am surprised how tight it is but i do not want to loose a lot of volume and thought about buying another 12w7 if i have to so i can go sealed. this sub is so loud that i do not see this making a big diffrence but i just wondered if you had.

I'm a sealed guy personally, maybe if I had one 12 like you I'd consider going ported but I personally like sealed and facing forward. Yes ported is 3 db louder, so what, I want the bass nice and tight, not shooting for crazy bass. Facing the box backward will be louder too, again I say so what, Those who listen to my car say that it sounds great.

Do you have the bass boost **** controller for your 100.1? If not get it, it'* like the best thing, dial in the right amount of "punch" to every song.

I wouldn't worry about going ported to sealed, It will be little quitier but will sound tighter. Why you making the switch? you can build a plexi ported box. just curious.

Side note, my buddy in a jetta with 1 12 Type R sub, sounded pretty loud in a sealed box, he got boared and built a ported box and it was excessive loud than, I was amazed at the difference in volume, bad side though, bass sweeps where muddy and didn't sound to good at all, he went back to the sealed box within a week.
