right to get started, happy new year to every 1.

just a few quick questions to all you boot installers that have gone for the home made option...

Q1). How do you decide on how big to make the sub enclosure??

i know you have to work with how many litres of air are enclosed but....
Q2). then how do you work that in to measurable sizes (mm/Cm etc)??
(i.e. 1000W sub requires about 27.4Ltrs of air unported, but if i was to design a box how will i be able to work out how many litres it would hold and would i have to include the magnet and cone on the sub in to the equation??)

Q3). is there any 1 who has made 1 that is flush fitting to the boot lock??
if so whats the dimenions of your box, the size of speaker and power rating??


ive tried once to make 1 but it didnt produce how it use 2. so i had to go back to the original box.
if any 1 out there is a designing whizz kid i basically have a 12" 1000W sub (SPLX) and would like to mount the amp in to the box so it can be placed under a perspex board also on the opposite side a power cap mounted in the same way as the amp. if any 1 has got some spare time and could work out the dimensions to get this sub in a proper sized box and need dimensions of the amp and so forth please contact me.

below is a working design that looked good that i once had but sounded absolute pants.(in the rear of me motor) and a design that i would like (drawing)

thanx in advance for any help!!

Hi,

Q1: The size of the box depends on the parameters of the sub. And on what kind of box you want to make (closed, ported, etc.). Programs like WinISD give you an indication. But most of the times the manufactures of the sub gives direction too. Max RMS has nothing to do with enclosure size.

Q2: On the site http://www.12vhifi.nl/ and http://www.12vhifi.nl/subkisten.html you can find all kind of info about carhifi and enclosure sizes. But it's in Dutch... The volume in liters (= dm3) is inside box volume -/- sub volume (inside the box). Also consider thickness of the materials you use (so don't use outside dimensions)

I guess there are sites like this one in English as well. Just google it.

bye, Eric

The box volume is dependant on the sub you use and what sort of sound you want (quick and punchy or low and loud)

Look on the manufactuers website or the manual to see what size box suits the sub you are using.

thanks guys just looking at these sites now.

eric - the box i used in the pic was closed but the box i use now is ported. do you know where i could get me hands on that program??

Rich - im after low and loud sound as i mostly listen to either garage or rnb sorta music.

Hi 83pps,

Don't know if it's any help, it's not really user friendly. Did you check the manufactuers site?

[83PPS]

nomen - i cant seem to find a web site for it any where. ive had a look on the box it came in and the manual but theres nothing there.... any clues?? ive tried searching for it on google but that mainly comes up with the reviews......

If you're lucky it's on this list:

http://www.selfmadehifi.de/params3.htm (in German...)

Else, post all the specs you do know and maybe somebody has an answer (brand, type, etc).

Eric

ps: also look at the FAQ's on this site (in English)

[83PPS]

yea ive check the faq's out but dint come up with much.... ok right just checked out that site and came to some thing close with the model. the model name on the box says SPLX SPL 1210CC (I found spl 210) and the main address is SAKURA AUTO PARTS LTD, GLASGOW. 12"COMPETITION SERIES WOOFER, 100oz DOUBLE STACKED MAGNET, 2"FOAM SURROUND FOR LONG THROW EXCURSION, DUAL 2½" BLACK ALUMINIUM VOICE COIL, 1000W, VENTED MAGNET STRUCTURE, HEAVY DUTY VENTED CONE, DUAL 6ohms.

the problem being....
would this be the right size box for the sub??
and would this look as good??

ne 1 got one (post pics) and have you noticed a differance between the left and right side as i am usually the only one in the car (in other words which would be better for the driver)

Those custom boxes are way too small. I've got an Auto Acoustics box and it's 0.5cl. My sub is very quick and punchy, but doesn;t drop very low.

You'll need at least 0.75 to get a 10" sub working properly, if you want it low and loud, you'd be better off with a ported box.

You'll need to get someone to design you a box if you don't know how. Speak to this man: email-me@efmax.info - Web site: http://www.x-bb.org/~efmax/box.htm
