So Im rigging up a NAOMI and PC in the same cabinet sharing the CAPCOM I/O as an interface to the cabinet. I see there are RCA outputs on the Capcom I/O and I'd like to sneak an 8" subwoofer into the cabinet. Can I simply buy an anplified 8"sub and hook it up directly to the autio out on the CAPCOM I/O or will a connection here stop the 2 cabinet speakers from operating correctly?
