    I like those directions. I would like to add one thing.

    In most cases I find it easier to biuld an MDF frame, attach the rings to the frame, then cover with a material. Then Glass.

    The back or bottom is left off so that we can reinforce from the back side. This minimizes body work.

    That is how this was done. All of the reinforcement and additional glass was applied from the back. When we were done the back was put on and the box was put in the vehicle.

    Glass is not difficult but it does require that you think it out in advance.

    Damn... That makes me want to try that out, and its way advanced for me.. I think I might try it, it would be better for me to make angles with it then angling and cutting wood.

    -Again it really not that hard, just plan in advance. First cut out a ring or many rings that the woofer or woffers will actually mount to.

    Then build the frame that will house the speakers. Attach the rings at what ever angles you want. Then stretch any material (fleece is preferred by many but not by me) tightly over the entire thing. Secure it with plenty of staples.

    Apply glass. Now if you use fleece and a lot of glass, its already pretty thick, however you still should add more glass and mat to the back side.

    A little body work on the front and your done.

    Lol very simple you would say. So you built it in your vehicle. Sit it there and go

    Couple of questions about this


    is Resin fiberglass? I never actually see him saying. "I lay the fiber glass"
    What is a router
    What is a dremer


    Now that I'm reading it, it does seem kindof easy if I have patience

    For me its about being different, everyone has a square box. This box is not that much different. The only part that is not MDF is the front, the rest is a regular box.

    The box is not built in the vehicle. It was built in the shop and installed when it was finished.

    Always do as much preplanning as possible. Once the box was built, the install itself took about an afternoon.

    I dont drive this car much, its a 1998 and it has only 55,000 miles on it

    Lovin the back seat. What are those back there. Amp, (something that starts with a C forgot what its called)


    Yea, well in my case, I can't make the box square. Therse a couple of "curves" reqcuired to do this. Mainly on the floor.... The front, back, and sides there is nothing there. It goes back a little bit more, then goes up to the back of the truck.

    Fiberglass (resin) by itself is weak, Thats why we use mat or weave. I usually cut the mat up in 4 x 4 inch squares, lots of squares, I dip it in the resin and lay it where I need it. This is done to reinforce your project.

    Always wear surgical gloves, the disposible kind, work outside,lots of ventilation, but take your time.

    We use a route to counter sink something or with the right jig, cut perfectly round holes.

    Do you mean Dremel? Greatest tool ever invented.

    K Fiberglass is resin. The 4 x 4 inch squares. Is it stronger if its smaller instead of a couple of 10 x 10. I have the disposable gloves, and I have outside.
    The router would be the piece of wood with the screw in the middle?

    yes a Dremel.. What is it used for or what is it?

    The router is the blue thing. The Dremel has many uses, depending on the attachment used. Its a cutter, sander, grinder, you name it, it can do it.

    Google dremel.

    Is that a cap I see mounted there????

    Did Viking see that???

    hhhhmmmmmmm

    My next project, I think I might try fiberglass....Looks very cool and much easier than I thought....

    Ranger, what do you use instead of "fleece"

    Yes, I have a cap in my truck, in my car and one in my sons car. I don't have the same dislike for them that The Viking does. However I do respect his opinion and his arguements against them is valid however, another discussion for later.

    I use t-shirts, they stretch very well and it is easier to get complete penetration with the first application of glass. The downside is that a lot more reinforcement is necessary. The problem I have with fleese is that it is hard to tell if the resin soaked all the way through. It really needs to on the first application. Because fleese is thicker, less reinforcement is needed.

    T-Shirt is also smoother, requiring less body work (I reinforce from the back side)

    My method is not the standard but it works for me

    and a damn good one. i use the same method on alot of stuff. i thought i was the only one that had this problem with fleese. on some panels i have to use to fleese but i always make sure i can resin the back side first.i use woven matt. unless i need chopped.

    here is a golf cart housing we make . i made the first one completely by hand. we made a mold and now they are popped out about 20 a day.We are building a website as we speak www.tech12volts.com. i will be doing a start to finish complete Nissan Titan fiberglass sub box which be painted in the next month or so. I will be posting deatiled pics and links on where to get the same supplies i use . please feel free to stop by or email me at james@tech12volts.com

    Nice looking golf cart "thingy" !!! LOL!!!!!!!


    looks good! Once that mold is seasoned, you can really go to town. I have done a little bit of that end of the fibreglasse world. not as much as you from the looks of it though. Nice work

    Its the reason many fiberglass boxes I see are cracked or flimsey. The glass MUST penetrate all the way through. If it don't, it doesnt stick to whats behind it.

    T-Shirt is also smoother after glass is applied, use a paint brush and put on a second coat and you have almost no body work. Thats my method any way.

    Any way its been tested many times and I like it. My glass boxes do not come apart.

    I like that white console, did you do that? I'm impressed.

    yes it was a pain also. about 20 hours of labor started with nothing. no idea what i wanted or anything. i started glassin about 13 years ago. went to work at boat plant on my days off from the shop. usually just sundays but they worked 7 days so it was cool .learned a lot. but still learning believe me. i very rarely use fleese unless i can get to the back of it.thanks again for the compliment. check out my website please. we just got it up and im working on the products page. www.tech12volts.com
