    I currently own a Peavey 15BX BW Cab and i'm about to buy a 810TVX by the same company.

    I've been running my combo amp into the 15'' Cab and i'm worried about what head I should buy to run the 1x15 and the 8x10.

    My 1x15 is 8 ohms and the 8x10 is 4 ohms.

    I dont know how this ohm stuff works, so what head would be able to handle both cabs???

    If you run both you get a load of 2.7Ohm (1/Z=1/4+1/8 -> Z=2.667 Ohm), which may be too low for your amp, which probably needs a minimum load of 4 Ohm.

    But with a 8x10 you won't need the 1x15 anymore IMO, so just unplug it.
    You can always buy a new head too, of course.

    Well I want to buy a new head anyways.

    So I would need a head that could handle 2 ohms??

    If you really want to use those two cabs - yes.

    You might look into a Carvin R600 or R1000. They both can run a stereo 2 ohm load, a stereo 4 ohm load, a stereo 8 ohm load, or a bridged 4 or 8 ohm load. Pretty versatile and inexpensive too!

    Versatile and inexpensive are 2 words I love to hear.
