I'm kind of new to car audio and I think im going to install myself. What kind of box will give me hard hitting but nice and accurate hits? Maybe someone could recomend a good website or company to look into for buying a box? (a box for 2 10" eclipse AL)

i would reccomend building your own box: the two types of boxes are ported and sealed. if you want more volume, then go with ported. if you want more SQ...then go with sealed. sealed are much easier to build...but you can get ported boxes to sound good

ok, I dont think I'm going to build a box though, to much, where could I buy a good sealed box? THanks.

You think its too much money? It will cost you under $50 to build your own box. A custom box could cost you anywhere from $100->$400. A well thought out, DIY box is better than any pre-fabricated box ever made. Wouldnt you like to save money?

I'de like to save the money but I'm already thinking I'm going to screw it up. I am good with my hands and all but I think I'de need a book on making a box. Do you have any suggestions on where to get that info? I'm reading "auto audio" as I type and its just now getting into boxes. C'ya.

Find the box section on the left.

Build your own box and save money man...its very easy, invite a friend over one afternoon sometime and get him to help you..

alright, I just finished reading that 400 page "auto audio" book and I have a better understanding about basically everything. I think I am going to build my own and do my own install, it just seems like if I build it I'll know I didnt get ripped off. I'll have to find out the recomended box size now and all that. I have a couple months to do some homework on all of it. The book said a sealed, MDF board, butt joint is the best way. Also, it said a trapezois box is superior to a rectangular one, sounds interesting to me, what do you all think?

trapezoid*

Yeh, I was thinking there wouldnt be much difference but a rectangular would e way easier. I just calculated a sealed box for a 10" eclipse, its 1.08 cubic feet. For 2 10's do I keep the same box dimensions just center the 2 subs?

different chambers? You mean like put a peice of board in between the two subwoofers? Also, Is that 1.08 ft^3 per sub? I'm going for quality but I still want hard hitting. THanks a lot.

oh, i made a mistake here. Theres a very simple looking chart in this book telling me anywhere from 1.0-1.5 is fine, but heres the more precise equation...

maximum box volume = 1.1 x Vas x Qt^2

for the eclipse 10" the Vas = 2.10cuft and the Qts = .47

Im to tired to figure it right now, im having prblems functioning at this hour. Tomarow I'll get back on and work with it.

That's 10 minutes more you'll have to wait to listen to it;)

are there any other websites for enclosure building? THanks.

Probably know all of it already, though.

How do I figure out like how deep it is ad how tall and how wide the box is supposed to be?

Alright, I think my last question was retarded after I looked at it. Using a formula from that last website that was posted I got 1.72 cubic ft per sub. That sounds correct and maybe a little big but rather big than small I assume. If any of you are pretty good at this (Jmac, Ss3079...) could I get your email to mail you a MSpaint sketch of the box just to make I got it right? THanks a lot guys. Later.

you can post that image up here.. just make sure it's something at or under 400x400 pixels and less than 30,240 bytes...

If my calculations are correct, that box is roughly 8 cubic feet(4 per sub) before displacements. I dont know how big you wanted to make it. If you need any help you can hit me up on aol at "clayrhye".

thanks. I really had no clue about how to make it at all. I'll rethink it today. c'ya.

Also, manufacturer recommended box size is not always the best way to go.

What about a box for a 10w3v2? It needs between .6-.9^3 of volume, and the recommended box is 18x11x9 (WxHxD respectively)

Thanks!
