Speaker box dimension of 15 - Kicker Solo-Baric L5 Car Subwoofer

It's quite simple, positive from amp to positive of speaker, negative to negative. Make sure it's getting sub frequencies only and not full spectrum signal. Next (if everything checks out so far) see if the box dimensions and ports are correct for your sub. The sub and box combo will have lots of factors when considering tuning of the box and port size. You can find all sorts of info on the website for your sub. Qtas, max excursion etc etc etc. They might even list a few total volume and port dimension sizes for the sub you have and your taste in music. It's quite a science to get it right. More than buying a sub and buying/building a box to get great performance. When you get it right though... music to your ears (and chest)

Hi,
I've had a look at the JLaudio website and they recommend 2 box designs, a ported and a sealed.
The sealed box needs a volume of:
2.125 ft3 or 60.2 litres.
To get this you would need to build the box to these dimensions:
22" x 16" x 14.75" or 559mm x 406mm x 375mm
The ported box needs a volume of:
3.50 ft3 or 99.1 litres.
To get this you would need to build the box to these dimensions:
24" x 19" x 18" or 610mm x 483mm x 457mm.
The port needs to be:
3.0" x 10.9" or 76mm x 277mm.
The enclosure recommendations listed above are external dimensions which assume the use of 3/4" (19mm) thick material. If you are using 5/8" (16mm) thick material, subtract 1/4" (6.5mm) from each dimension. Do not use any material with a thickness of less than 5/8" (16mm) as this may compromise the rigidity of the enclosure.
• All enclosure volumes listed above are net internal volumes! Driver displacement, port displacement and brace displacement must be added to obtain the final gross internal volume. All enclosure dimensions above have already taken this into acount.
• When using two subwoofers in a common enclosure simply double the required volume and, in the case of a ported enclosure, use two times the recommended port(s). Likewise, when using three subwoofers in a common enclosure simply triple the required volume and, in the case of a ported enclosure, use three times the recommended port(s).
• We recommend the use of this speaker in a bi-amplified system using high-quality satellite speakers and a high-quality amplifier. We do not recommend the use of this subwoofer with a passive crossover (coil), as this type of device will adversely affect performance.
As you can see it all depends on the space you have available, whilst the vented box will give you a more efficient bass responce especially with the low range frequencies.

If you to go and look at the information about your sub woofer and find out all the information about building or buying the correct enclosure then this is the link to the pdf file I found:
The enclosure info is on page 3:

http://www.sonicelectronix.com/item_13203_Kole+Audio+KMX-15.html look at the specs, you should use 3/4 plywood or particle board, roughly 19' tall 19'' wide and 10'' deep

Any type BOX will do...This ensures all the thump to be pushed forward to give all the sound from the speaker forward....enjoy. Alow enough room to get you hand in to wire easy and you should be good.

What sub? And what volume do you need? First off you will want to go get yourself a sheet of 3/4" MDF, nails, resin, etc. You'll also want access to a table saw and drill. Decide how much volume you need and then settle on some dimensions to achieve that volume.

Draw a pattern of the sub on the box then take 5/8 of an inch off the inside,that should let it slide in easy.

10" subs need 1 cubic feet. 15" subs need 2.5 cubic feet. install them on its own volume of the box...

The cutout simensions for the kicker 15" solo baric are 13.75".

do you want the box ported or unported (holes or no holes) if you don't got a lot of room than you dont want a ported box. keep in mind the box has to have the correct amount of cubic air space or you could seize your sub... if you're building it make sure you use OSB board (oriented strand board) or MDF board(medium density fiber) your sub needs .7cubic feet of air space in an unported box

The owner's manual states the ported box should be:

• 4.00 cu ft.
• Port diameter = 4"
• Port length = 14"
  

It doesn't mention round vs. rectangular port. For more details, you may want to contact Orion.
