Dimensions for Orion HCCA 10?
 

what dimensions should i use for the HCCA? i'm gonna be getting the 10 inch model. i already have 3/4 inch mdf, will that be thick enough for the box?

The dimensions of your box is really not the question. Its the volume you need to be aware of. that sub should be mounted in a fairly small box,
Sealed Box Volume 0.5 - 0.8 cubic feet
Ported Box Volume 1.2 cubic feet
The dimensions are up to you depending on where you plan to put this box and the space available.
a simple .8cf sealed box would be 13x13x12
a simple 1.2cf ported box would be 16x12.5x14.5
The 3/4 MDF will be fine but make sure you use a really good wood glue (I like to use a few screws as well)Use that Lepage no more nails adhesive. Its the best and its pretty cheap.
That's a badass sub, I love Orion gear.

ok thanks man. Do you think this sub will be louder than my 2 g5's i already have? i'm selling my g5's along with my alpine mrp m1000 amp and i am kinda iffy about this.. i'm getting this orion with an Audison LRx 1.1 (1100 watts rms). i just want something louder and hoping this will be alot louder..

Ive never had the G5's from Boston. I had a bunch of Boston pro's and they were stupid load. Thats a hard question for me because I don't know a hole lot about those subs or that amp.
Anyone else have any ideas???

If its loud you want, build a bandpass box.wont get much louder then that.
