    so I've done some looking around and got half of my questions answered. I have a GK backline 2:10 cab and a backline 1 15 cab. both R rated at 200 watts an 8 ohms. I also have a gk backline head at 125 Watts at 8 ohms. Can I use a speaker Y cable out of the 1 output of the head to the 2 cabs?
  2. If you have the BL250 it is not rated to drive two 8 ohm cabs (total 4 ohm load). The 250 is only rated for a 8 ohm load.

    Does it have a 4 ohm rating.

    Your 2, 8 ohm cabs in parallel would be a 4 ohm load.

    You can put the 2 cabs in series, to get a 16 ohm load, but you'd loose output (wattage).

    If your head does not have a 4 ohm rating---don't run your 2 cabs in parallel.

    Thank you so much. The guy at the music store said it would be fine. It's not rated at 4 ohms at all. And each cab only has 1 input also.

    I'm sure he knew what he was talking about.
  6. That was joke right? :)

    The BL250 is not designed for a 4 ohm load, if it could handle it 4 ohm minimum would be on the amp case. 8 ohm load only.

    I think this post is simply missing the "................." at the end...?

    Would I be able to safely hook up both cabs with a dual output 400w head or will it blow the speakers?
  9. You can use two 8 ohm cabs with any amp that says 4 ohm or 2 ohm minimum load. Blowing the cabs will require power input from the amp head to the cabs and that is controllable by you.

    Running the amp BELOW its ohm rating will lead to letting the smoke out of the amp while the speakers laugh.
