    question about fiberglass enclosure.

    Im planning on making a fiberglass box for two 10's and two 12's. I was wondering about how the fiberglass is actual attached to the wooden bottom and back. what stops it from just pulling off. I hope this doesnt sound stupid. I know that you staple the first sheet of material to the box after stretching it over everything, but is that all or does the resin bond with the wood.

    Thx ALOT for any help at all.

    the resin will bond....kinda like the screws for a wood box are only there to hold it together until the glue dries.

    so the resin will bond with the wood. I guess what im trying to say is that the bottom and back are wood. do i need to cover that in fiberglass too? or will the bottom be uncovered, like if you were to look under??

    it should just bond to the wood....no need to wrap all the way around.

    yes, generally speaking, it is a bad idea if you plan on sending the same freq. through both....if your really good with x-over points and can make them work with each other, then you the man.

    Re: question about fiberglass enclosure.

    you can leave big area of wood uncovered, just make sure there is plenty of overlap of the glass material and the mdf.

    Definitely do not mix sub sizes, 4 10" or 4 12" depending on how much room and power you have.

    Re: question about fiberglass enclosure.

    Would it be fine to seperate the two with the MDF. like make a barrier, or will i just be getting into more than it is worth. I really would like to keep the speakers that i have now if its possible. Thanks for all of your help. BIG help. ill have plenty of pics. can you mix two different brands?

    Re: question about fiberglass enclosure.

    One more question, what would be a good resin to use? Ive been looking around and ive seen some boat resin that is really cheap( $38) for a gallon and some well over $100. Does it matter if it has wax in it?

    realistically, you can do whatever you want. however, mixing sub sizes without properly corssing them over will result in very poor sound quality at best. it has nothing to do with seperating them internally....seperate them by putting them in different cars would work.

    as for mixing brands, i wouldn't do that either. every brand does not perform the same. i wouldn't take a 12 road gear and a 12 DD and say i'm running 2 12's....there are too many variables to consider.

    bets bet, pick the sub you like best out of what you have. sell the others and buy another to match what you kept and build from there. you cant just throw different brands of different sizes together and expect something good to come out of it.

    Re: question about fiberglass enclosure.

    i get all my glass material from home depot it works great!!

    if you have never did glass workbefore get ready!! its not going to be some day job! and if you plan on painting the finished product you better have some body work/body shop exsperiance if you plan on making it look nice.But hey you live and learn just go ahead there is a ton of do it yourself glass online.

    and miss matching subs are a crazy idea i would never ever do! nor mixing 2 different size subs unless it 12 and 8's or 15's and 8's imo i would never run 10's and 12's or 10's and 8's i like running 8's with 15s for good mid bass.

    everyone has opinions but thats just mine.

    If you are talking about the mounting diameter, my alpine 12 is 10.9".
