Choosing your subs

Make sure your subs need no more than 6" of mounting depth. The standard cutouts are 7" for 8s and 9 1/8" for 10s, and the box can be cut to your sub's own diameter when it differs. Type the sub model in the "What Sub Model are you using?" box when you order so the box is cut to match; the specs are looked up from the model if you are unsure of the cutout. Shop 8" subwoofers or 10" subwoofers.
