I did some initial measurements for the entire volume I could use without a complex box. After Wood displacement I had 22 cubic feet of internal volume .

So before I started building I needed some much needed upgraded wiring . ( 6 25 Foot Rolls of Audiopipe 0 Gauge CCA) 4 Runs 2 Positive, 2 Grounds
