Hello,   I am a little confused on how to connect my Marshall DSL100 head to my Line 6 4x12 cabinet. The Marshall has two 8 ohm jacks and one 16 ohm jack. The cabinet has two 8 ohm jacks: one 8 ohm jack is wired for the right two speakers and the other 8 ohm jack is wired for the left two speakers. How would I connect the Marshall to the Line 6 cabinet without damaging anything? Thanks
