View Full Version : Inside of Sub box question

I am thinking about redoing my trunk setup (have 1 12" alpine and 2 amps) and I've seen people do something where they have a normal sealed box but have a plexiglass window on the back so you can see the magnet and stuff and then put some LEDs in to make it look better...

Anyways my question is, since you can see the inside of the box when you do this, what do you coat it with or line it with to make it look nicer other than the normal MDF look?

That's what I thought, but I just wanted to be sure. Thanks guys! Oh and one more question. I want to make it so that there is like a baffle (MDF) all the way across the span of the trunk, with the window in the middle and the sub box in front of is basically (or behind depending on which direction your looking) but anyways that way the baffle covers everything except the window where you can see into the sub box. What would be the best way to do this?

Would I just build the box with 5 sides and use the baffle for the whole 6th side (rear of box)?

build the box. install. measure and make the baffle. 2 separate deals.

I love this site. You guys give me all sorts of crazy ideas.

I would have thought that plexi would be too flexible for a sealed box. How thick is the glass you are using for this?

Not very thick (got it from Home Depot), I've heard about problems with flexing and stuff, do you think I'll have problems and whats the disadvantage with flexing? It's a single 12" sub powered by 600 watts rms amp. I've heard some people use lexan but isn't that stuff is kind of expensive? I suppose I could use real glass couldn't I? I got a majority of the box done today, but if the plexiglass I have doesn't work out I can always just swap in some thicker or stronger stuff later. What I did was make the box with only 5 sides and then use the baffle as the back side with a cutout where the plexiglass goes for the window. Anyways here's some pics showing what I've done so far, let me know what you think, but be nice, I'm new at this ;-).

It's hard to see in this photo but the window is there its just not reflecting.

Next to the sub on each side is going to be the amps but recessed behind with windows also and then I'll carpet it all (black) and add some LEDs. Let me know what ya think...

I'm not sure exactly how it works, but I think flexing will take away from the performance of the speaker. Not to mention, when it flexes it will change the air space of the box, and probably rattle loose the silicone, or whatever you will use for a sealant. It might even vibrate. On top of that, you need it to insulate quite well so none of the inside sound escapes the box.

If I were you I would talk to a glass shop and try to get something thicker. But if you have it in there, why not try it out and see what it does.

Other than that the rest looks awesome. That is going to be a sweet looking enclosure. Very nicely done.

You are correct... That is what I have come to know as the truth. Flexing = bad.

ltkenbo
05-06-2008, 12:43 PM
Yeah I'll have to test it out once I finish, like I said it wouldn't be very hard to swap in something thicker. Also what might help with the performance thing even if sound waves escape from the back is that I guess the baffle in a way helps isolate the front from the back (kind of like a infinite baffle enclosure). I'm gonna work on it some more today so I'll upload some more pics later.

Yeah I went to Lowes today and picked up a 1/4" piece, its a whole lot thicker and doesn't flex unless you put a ton of pressure on it (especially with the small size of the window). Anyways, I swapped it out and also got the sub amp mounted. Now all thats left is the 4 channel amp mounting and put the 2 windows in, paint the inside and then put it all back in the car. Of course I still have to carpet it too but I don't have like any money right now so I gotta wait like a week or 2. Here's some pics of what I've done today, I'm hoping to finish tonight, things would go so much faster if I had a table saw and saw horses and just better tools in general.

I also thought about adding some PC fans for cooling and for the look like on the sides of the amp mounts. Let me know what you guys think.

Already thought about that just gotta cut the holes. The way I have it designed too is so to get the piece off that the amp is atually mounted too, you just unscrew the screws in the rear and pop it off.

lookin pretty good, fairly well thought out and should be really nice when you get it all finished up. Have you decided on what you are going to finish the inside of the box with? and what sort of lighting you are going to use as well? Should come out really nice if you take your time and don't go over board.

I was going to do something similiar to this. Since the plexiglass allows you to see inside I was going to use special paint(s) and install black lights inside the box that way it "pops" out at you.

ltkenbo
05-07-2008, 09:16 PM
For now I'm just gonna use white paint, but once I get some money maybe some vinyl. As far as lights goes, I'm gonna use 3 9.5" million color LED strips from oznium.com for the inside of each compartment. If I ever get a yellowtop battery I could also make fourth compartment below for it.

Ok so here's the update. Got the second amp mounted, took a little longer because of clearance issues with the rear speaker so I had to recess it like 1" less and use some thinner mdf for a for 2 of the sides, but you can't really tell. I was putting in the thinner plexiglass for the amp windows and was drilling the holes for the screws when the bit broke and then my drill hit the window I was creating and cracked a big chunk out of the plexiglass. So I have to get another piece but I put the other one on and decided just to use silicone since it won't be under any significant pressure. Here's what it looks like:

Hey Look! There is a Civic on that sub enclosure! lol.

That looks very very nice. Think that the amps will have heat sync issues? I had a similar setup in my F150 and I had major issues with the amps cutting out because they got to hot. The amps are fine though, obviously it's a trip to avoid damage. It was really annoying though.

I'm spending a lot of time learning about these enclosures so I can possibly make my own. I need a pretty custom application for my Sport Trac.

I didnt read the whole thread but I built a box using 1/2" plexi and had flexing issues. I just doubled up the 1/2" and it solved the problem. But I spent about $85 in plexiglass

I don't know much about the Alpine amps, but I had my Pheonix Gold Xenon 100.4 running two 6x9's and my Xenon 10 in my half ton. I crammed it into a tight spot much like these are. I cut vent holes in the sides, and carpetted over the holes and didn't have an issue at all. On some of my road trips that amp was kicking pretty hard for a long time.

So I was in Ireland for 2 weeks so I haven't had time to finish everything in the trunk. I did get a lot done. I ordered the carpet and LEDs (million color ones they fade through all the colors) and installed them the other day. I also decided to go with a trim panel (1/8" MDF) for the carpet that way I cant remove the trim panel to get at the main screws whenever I need to remove something instead having to peel off the carpet. Another thing I need to figure out is a way to attach the edges of the carpet that cover the edges past the window that's why in the pictures the windows look a little crooked cause the carpet is not fastened down I need a temporary solution for this so if anyone has any ideas let me know. I still have to cut a piece for the floor panel and then do something about the sides.

Here's the pics, let me know what you think.

ltkenbo
06-17-2008, 02:41 PM
It just looks like that when its not attached because you are seeing the overhanging edges for the windows which cover up the exposed wood on the main panel, also I didn't trim the sides perfect yet. The actual carpet is really flat except where the edges need to be secured by the windows.

Nice. I have to make my first attempt at fibre glassing to make the sub box for the dodge soon.

It would be nice if you could cover the back of the seat too hey? You can see the blue frame and the foam through your trunk hinge openning.

I gotta say though, I am very impressed with this build. Especially since it is your first build.

So yesterday I worked on the cover panel for one of the sides. Decided to go fiberglass. I Masked off everything and then use some cotton (t-shirt) and stapled and hot glued it over the spot where I wanted it to go. Then layed some fiberglass on top of that.

So here's the work so far, still gotta trim (gotta get a dremel) the fiberglass and then maybe sand it a little bit and then carpet it.

07-06-2008, 03:51 AM
honestly, fiberglassing the sides in with the box, if you had a back or up facing box would of helped more, but since your trunk is sealed off to begin with, you wouldn't notice a difference besides cosmetics in sound. but if that's what you intended, im wondering what the finished result will be. maybe if you fiberglassed the box with the sides to create one essential piece, that would look sweet.rather than carpet meets fiberglass you know

ltkenbo
07-06-2008, 04:05 AM
These pieces aren't not meant to affect sound, these are just to cover up the ugly gaping holes so the trunk won't look like crap. Why make the rest look nice if I have those gaping holes? That whole thing is not the sub "box", only the individual compartment for the sub. Plus if they were permanently attached to the baffle, it would be impossible to get it out of the trunk especially with the length of the baffle, it's just for looks. Read the whole thread to see what I mean.

Here's with the panel (obviously it won't look exactly like this since it will be covered with carpet and such...):
