Is there any way to run two cabinets rather than just one with the Headbone?
Yes there are two ways: (1) You can use the parallel jacks on the cabinets – most have these, by connecting speaker cable into the next cabinet, or (2) you can split the output using a Y junction box or Y cable. We suggest you make up a simple Y junction using a metal box and 1/4″ connectors. Make sure you use heavy 12 gauge wire inside for proper signal transfer.
