12w7 enclosure

[shorty24sev 10+ year member]

Okay My dad and I have cut all the sides of my enclosre for my 12w7(diidnt buy yet) running off a jbl 1200.1. My first question is, is 3/4 inch thick wood good enough? I was talking to a guy at tweeter and he said the front peice should be 3 inches thick. Is this necessary? Also, will i need bracing or anything for this box? Lastly, can you tell how to wire the subs to get a 3 ohm load. Do i put the pos. on the one connector and the neg. on the other? thanks alot for the help.

Just wire + from sub to + from amp and - from sub to - from amp. The 12W7 is a single voice coil with a 3ohm load...

The JBL1200.1 should be giving that sub about 1,050watts, just about perfect for that sub...

Please check out JL's enclosure specs... http://www.jlaudio.com

The face of the box should NOT be 3" thick like the salesmen at tweeter mentioned, but 1.5" (two 3/4" sheets stacked)

Put it in 1.85 cubic feet sealed, build it solid and take your time, and minimal bracing should be needed.

Make sure you make it perfect. The W7's are very fickle with performance in the wrong enclosure.
