Running your head into two cabinets

Absolutely. Our amps have two speaker outputs, so you can build your own modular rig — just plug one cab into the bottom speaker jack and one into the top. > One important detail: the "4 Ohm" jack has a special contact that increases the amp's output for extra headroom. Only plug a single 4-ohm cab into it. Plugging a single 8-ohm cab into the 4-ohm jack doubles the output power and strains the amp. An 8-ohm cab should only go in the 4-ohm jack if there's also an 8-ohm cab in the 8-ohm jack.
