    OK This may sound a little crazy but just bear with me...

    Story:
    I wanted to do a custom sub set up in my Evo but putting a box in my drunk is out of the question. My trunk always has stuff in it and I just don't want to put a box in my trunk. So I picked up two of these to put in my rear deck as an IB set up http://www.partsexpress.com/pe/showdetl.cfm?Partnumber=264-832 . It sounded OK but not great .

    So I got the speakers and I have an idea. I figured I could take one of the 6.5s and build a small sealed box to go in my rear armrest holder(see pic). The armrest would still be there but the box would just be filling the spot with the 6.5 sub.

    I know its not as easy as taking measurments and a building box. How do I go about finding the right airspace for the tiny sub? The cubby hole is 8"wide, 13"long and 6" deep. Any help would be greatly appreciated.

    why not mount something bigger in the rear deck, in an infinite baffle?

    Not to sound rude but please explain why it wouldn't sound good?

    I'm not going for SQ or lots of deep bass. I'm just looking for a decent in cabin bass. Bass you can hear not feel if that makes any sense.

    I can't put anything larger in the rear deck cause I just don't have the knowledge or time to cut or fab something like that. To me the 6.5 is just a easier solution.

    Honestly an IB setup would be very easy. For a first time user all you'd need was some MDF/birch and a jigsaw. Take less than a couple hours for a first-timer.

    a 6.5" sub isn't gonna do jack shit.

    Says the guy who's never heard these subs [​IMG]
    or even these:

    [​IMG]

    Are they a bit expensive? Yes, but they sound amazing given the size of sub that they are. a set of 3 or 4 of them would be enough for most peoples tastes... Are they going to slam like an SPL sub? No way! But they fill out those bottom octaves very well for the space conscious people out there.

    (btw, those TB speakers that he referenced from PE will work just fine as well...it doesn't sound like he's looking for miracles, just better sound)

    I seriously don't understand how thay would sound that bad. I mean damn the sub will be 3ft away. I've been scouring the net using the various programs and websites trying to find out if it will work. The subs require .25 for a sealed enclosure and if I can find some .5" mdf its a perfect fit. I'll be putting about 100w to them and if it sounds anywhere near the sound of a 2.1 pc speaker set i will consider it a victory.

    I'll see if I can get this done in the next couple of days.

    But, have you heard their 5" subs? If you had, I doubt you'd say a small woofer won't work.

    they can't... but a lot of people go for the higher chest beating bass.

    have you heard the wave radio? I guess for the size it's good... but it's nothing I'd want to trade my home theater for. Not to mention the recockulous price.

    with a very old tech, that they claim to have come up with... plus bose fart like crazy on the low bass notes, because they use tiny drivers to make big sound.

    yeah i know. but they aren't all that bad for what they are. just over priced.



    anyways, I think you'll be fine with what you're trying to do with those drivers. hell try some different configurations. do a downfiring enclosure in the armrest hole. it'll give the sub something to load off.

    Why do companies make 18"+ subs, when an 8 to 10 is just fine?

    No doubt, the 5" sub WILL NOT cause heart stopping bass, but it will fill out the bottom octave a bit for those who want a bit more bass. The OP stated he isn't looking to be heard from miles away... instead he wants bass you can hear, not feel. He made a good choice for himself, you and I will probably not be satisfied with the amount of low frequency reproduction, but it will do the job he desires.

    So I spent a good part of my day building this box...

    Things I have learned are:
    1. I suck at making boxes and working with wood in general.
    2. see above

    pics to come later.

    well I'm way too embarrassed to post pics as the box sits right now but I will tell you this....

    I think my main problem was measurement. Trying to make a box into an exact fit is not something for rookies. My 'second' box is drying now...

    Also when building a sealed box the key word is 'sealed' or else it will sound like pure shit. Thus is why the second box is drying now.:o

    On the bright side it has a lot of potential and did sound really good before I found all the air leaks:hs:

    Edit: also I was using 1/2" mdf which didn't make life any easier
