greetings all

im upgradeing my sound system with new headunit and 10" sub. i wanted to build a custom shape sealed sub box so that it could fit btween the two rear deck speaker boxes. i want to do this becuase trunk space is important to me since i fill it to th top with junk all the time. heres my quesionts: is it posible or not advisable to take a pre made box like this one - http://cgi.ebay.com/ws/eBayISAPI.dll...category=14945 - and make it into the shape i want to, (keeping in mind the cu ft air disp i need)? if so do i need special glue, nails, etc so it stays airtight and wont fall apart? i would be even more pleased to hear if its ok to put the sub amp and dist block inside the enclosure, it would save alot of space as well, but would too much heat build up, being contained in an air tight container like that?

comments and advice badly needed !!! thanks guys

I wouldnt put the amp inside, too much heat. you can chop the box anyway you need, you will sacrifice a bit of boom however.

yah the amp probally will overheat in a tight space like that it needs somewhere for the hot air to go.....and if u change the box use screws not nails

I personally would make your own box for your specifac need,instead of chopping one that is already made.. I would use press board and screws... also I would use some sort of latex to fill in the gaps and crevices to make sure it will be air tight with the sub in there.

latex sounds like a good idea. what is press board? where can i get some? what thickness do you suggest?
thanks

its pretty much just wood pieces pressed at severly high pressures and glued together its alot cheaper than solid wood and its farily strong.........lowes, menards, home depot, any hardware store that sells wood its not that hard to find cuz tons of places carry it

Building a custom box is a lot harder than it seems, and modifying a prebuilt one will most likely ruin it.
Go to http://jlaudio.com/tutorials/magic/index.html for some great info on enclosures and in another place in the tutorial it talks about making a custom box and the variables you'll have to deal with.

I'd say stick to the one you picked out (or any other MDF box), avoid fibreboard or compressed pulp wood, or any light solid wood for that matter.
Make the LEAST ammount of holes in it (with screws or drills)
and don't even think of putting anything inside it....
If you're looking for space, try mounting the electronics on the roof of the trunk

Just take you time and plan it out, and building a sealed box will not be that difficult. Other box designs like ported or bandpass are a lot harder to build simply b/c of the accuracy that you must have to build them. Use some MDF from the hardware store, unless you can find HDF, and make your own box. The results wil be worth the effort. You can mount the amp inside the car if you have to, mabey under the seat or somthing.
