    My only recommendation is to put a post in the middle between all 4 so you can staple the fleece to, gives you a better curve, and we all know that FG is stronger in a curve than in flat areas

    I admit from the start that I didn't read every word in this post. But, from what I have seen, it seems to me that you decided to build an MDF enclosure to house 4 MTX subs. It also seams that you

    1. Didn't have the whole thing 100% planned out when you began.
    2. Didn't know exactly how much structure the enclosure would have until posting here for advice.

    If my assertions are correct, then I can only assume that you haven't taken any of the T/S Parameters into account when building the enclosure? Have you even calculated box volume, taking into consideration the required volume for these woofers to perform? If not, then I hope you understand the ramifications of this. The drivers will not perform well at all if the enclosure is not built to spec. Buidling fiberglass enclosures is extremely difficlut for this reason, especially ones of unique shape. If you haven't taken the woofers specs, T/S, into account, then you may want to do that before you spend all of your time and energy on an enclosure that could wind up with a host of issues and terrible sound and performances from these woofers. The end result could easily be 4 woofers that sound worse than 1 woofer in a proper enclosure.

    I breezed through this pretty quick but I noticed that you were unsure if the magents would affect an LCD as they do a CRT -- no an LCD does not care about magnets

    well az for the lcd's, i got the correct info and a descriptive explanation that told me they were not affected by magnets.

    as for the t/s specs i dont know what that is. all i know i
    s that i enjoy working with car audio and im going to screw up many times before i get everything right. but the experience i get from my mistakes and the help i get from these forums, which i guess these forums are for, will make me better one day.

    so keep giving me the feedback beacause it only helps me.

    now as far as the fleece goes which is the best way to go common utility stapler, air stapler, brad nailer, or spray adhesive??

    HOLY ***** sparky, listen to what you are being told by people who know better. The T/S numbers are listed on the documentation that came with your subs, Thielle/Small, read here http://usuarios.uninet.com.br/~edelima/WBsezout2.htm

    You want help, but brush it off when it is given to you. Rather than spoonfeeding, read every other post here and look on the12volt.com and read there. A good way to **** off an installer, is to discount the advise they are giving you.

    Aug, I appreciate a willingness to Experiment, Err, and Learn. I started like that too. But you are forgetting the most important part....Research. Its Research, Expirement, Err, and Learn. Thats how you get REEL good. Not my acronym so don't throw cheese at me . Seriously though, there are some things you can do wrong with car audio and learn for next time while still turning out a functioning and mostly useable product. Ignoring the parameters ment for designing an enclosure, ESPECIALLY box volume is not one of them. Its a recipe for disaster. Not only is it a strong possibilty that your bass could sound like garbage, and not only is there an almost certain likelihood that your woofers will not perform to within 50% their potential, but you could actually damage the drivers themselves. You dont' have to partake in the immense task of fiberglassing to exact T/S parameters. But I really think if you are going to spend your time and $$, that you should research a bit more before diving in here and at least try to get the enclosure a little closer to the right air space for the woofers. Find out if they want to be chambered and make sure you've provided enough clearance between magnets and the base of the enclosure. Thats not a lot to do, but it may require major adjustments considering you've already begun. But it would be worth it. Especially considering you're using 4 subs. DO you really want to have 4 subs in the trunk that sound like one crappy sub?

    here is where i am now!! my first sanding got it pretty smooth with just a couple of holes here and there. i went over it again with some rage finishing filler. i am going to sand it down one more time before i wrap it. i decided to just wrap it in vinyl, cause the way i did it the surface would not be real good with paint!!

    hey man, if you just keep sanding, it will be good enough to paint! What you don't want is a crap ton of that filler left on the surface if you do paint it. If you use a filler that doesn't absorb water (i don't think the decent ones do) when you start to get smooth, spray soapy water over the surface. It gives you highlights to see what the paint might look like, and makes sanding quite easy.

    Take Go's advice and keep sandingl. Vinyl won't hide as much as you may think it will. Vinylling is also not an easy task. You've done all this hard work, just keep cranking away.
