My set-up: Katana 100w Head running on 50w setting. Mojo 1x12 with Celestion V30 8ohm What I need help with: I want to add another 1x12 cabinet to the set-up. Can I just order another duplicate? And if I do that, how do I wire it all up? Right now my cabinet has one speaker jack in the back of it. Do I need a different jack? And will I be okay running two 8ohm speakers with an amp head that calls for 8 or 16 ohms? Sorry if the questions seem rather noobish, but I am a complete noob when it comes to speakers and amps, and reading the information found on the internet is only serving to confuse me a bit more.
