Hi all

Picked up a couple of 2x12 cabs and I have a blackstar id100 top head? My question is do I need to wire both cabs in series (8ohm x 2 = 16ohm) then can I put on to each out put says a min load of 8ohms

Thanks in advance ed
If you have 8 ohm speakers in those cabinets, you can wire each cabinet in series to produce 16 ohm cabinets. That way, no matter how you use them, you won't  have a minimum load less than 8 ohms. 
You can also wire them in Series-Parallel and keep them at 8ohm, if that's what you want.
