MTX Thunder 8000’s

if this is for 2 subs, just go down to your local shop and take along a measuring tape, tell them you're making sure something like that can fit in your trunk or something, then ask your friend to make something with the same dimensions.  Be sure to have him place a board between the subs if the one you're looking at doesn't have one.  in all reality it won't really be necessary to have the middle divide if you figure out the sub is blown first.  If one goes you'll notice right away.

to sto the liscence from rattling all you have to do is put some foam tape on the back,mit's really not hard, or you can go to any place that sell dynamat ( a brand of sound deadening material ), and find out if they have this cool thing i bought that you put on your liscence plate that stop all the rattles.  The foam i was talking about is the expanding kind that you pour into your trunk.  One ofthe added benefits of this is also that if you let it expand out and keep adding little bits more, when it's all dry you can cut patterns and shapes into it and cover it with carpet or fiberglass or whatever.  And the last question you had.........the foam stops sound and rattles like this.  The foam captures air in all the little pockets it makes when it expands.  Dead air kills sound, aka rattles.  Also, if you have ever noticed how a rattle will stop if you simply put a tiny pit of weight or pressure on it?  When the foam expands and hardens it puts some pressure on what it's touching further decreasing rattles.

I know what you maean when you say it's rediculous how someone can charge huge amounts of money for simple stuff.  I used to buy all my stuff until about 8 years ago i found out what a sheet of mdf costs and the carpet that goes on it.  It like if I make a box for a guy and i charge $100 for it, then i can make 3 mor boxes off of the one guy, doing the math........you kinda see why some people will charge so much.  Onje guy can pay for every one elses intall for like a month.  Hope you like the subs, looking foward to the pics.
