Tower is currently wired for two cans (had a pair JL 7.7's running back to a Clarion APX 490M on channel 1 and 2). So I assume 1 speaker per channel was running at 4ohm (The 7.7 cans got destroyed---Long Story... Just bought a pair of the Wet Sounds XS650 Double Barrel Speakers . Do i need to run more wire through the tower and connect each speaker to channel 1 and 2 (2 wires on channel 1 + and 2 wires on channel - etc. at 2 ohm) or can I connect the existing wire to 1 speaker and jump positive to positive and negative to negative on the second speaker with a small 2" peice or wire?
