The modification process of the 10" Adire Brahma into a JL Audio Stealthbox - I used 3 plates of 3/4" MDF = 2.25" Spacer, and secured that to the stealthbox w/ eight 2.5" Machine Screws (bolted on the inside) and nearly an entire tube of liquid nails. The brahma is held in place w/ eight 1.5" Sheetmetal screws into the MDF.
The jig we made to cut a nearly perfect circle.
1/0 Gauge under the hood.
