Choosing your subs

Check your sub's specs before ordering: it must need no more than 5.25" of mounting depth, and a sub larger than these specs may not fit. Type the sub model in the "What Sub Model are you using?" box when ordering so the box is cut to match; if you have not picked subs yet, ask which ones will fit. Shop 8" subwoofers or 10" subwoofers.
