anyone got any ideas or suggestions on building a box for 2 12inch solobarics for an ext cab ford ranger...... thanks
Well I tried to model what the frequency response of 2 ported 12" L7's would be in that small box... NOT GOOD. The recommended size for those would be over 7 cubic feet(even larger for a Butterworth response curve). But good news... the good folks over at stillwater designs suggest a box precisely that size for a sealed SQ enclosure! You would want to use a divider, and brace the insides with right-triangle cuts of wood to prevent flexing, and due to the immense power and sheer weight of those subs, use 1" thick MDF for the side the subs mount to, if not all sides.

Have you built any boxes before? I'd be happy to help with the final design of the box, but I need to know how much space is back there. Have you crawled in with a tape measure yet? To make it easier, give me the maximum HxWxD and I'll get back to you with some figures. Also, what kind of music do you prefer? If you want a sealed box, you could have figured it out yourself, so i'm guessing you want a ported one. Count on needing about 6 cubic feet for those.
A ported box in an extended cab ranger is going to be a challenge. But (hopefully) not impossible.
1992 Chevrolet pickup; Jensen VM9412 HU; Alpine 4x6 2-way dash speakers x 2; Pyle Blue Label 4x6 3-way rear speakers x 2; Pyle Blue Label 12" subs x 2; Crunch GVP700.2 "Ground Pounder" subwoofer amplifier; Custom Subwoofer box
i have an idea of what size.....top depth 12in, bottom depth 16in, height 19.5, width 36. these are what i measured to fit, dont know if they will work tho
No problem if the box is just gonna be sitting on the back seats. You need a bandpass box, custom made to fit back there, or 2 ported boxes.
there any way to get a ported out of them measurements?
By those dimensions, you're box would be approximately 5.6 cubic feet. A ported should work, but I'm no expert in ported boxes, so don't hold me to my word.
which ports should i use? approx where should i put them? and should i put a divider in the middle of the box or no? thanks
If you built your ported box to precisely those dimensions, it would have a net internal volume of under 4 ft, using 3/4" MDF. A bit small.
I can definitely design a vented enclosure with those figures, but the tuning frequency may need to be higher than some would prefer. I need the exact model number so i can pull up the theille-small parameters.
Are you dedicated to using 12's? With the dimensions you gave, a single 15 would be perfect.
Whoops, forgot about factoring in the thickness of the MDF.
08 S12L7D2 i would rather use 2 of the 12s but i guess if i had to use a 15 i could, but i prefer not to....thanks
A typical brace is just a small square, cut in half diagonally. If you don't have it already, download the owners manual. It has pics of braces on page 3. How many is up to you. Each one will add strength to the box, so having one one every seam would be nice. They're easy as pie.
