Rewiring a Behringer 4x10

[Vr6spd]

I have recently switched from guitar to bass and I not too familiar with hooking up multiple cabs. My amp is a GK 700RBII. I have been loaned a Behringer 4x10 ultrabass combo and 1x15 from my friend. I know Behringer doesn't get much love around here, but the price was right, FREE. Plus my friend says as long as I don't sell it I can do anything to it. The amp was bad and we removed and installed my GK amp. The 15 is 8 ohm. The 4x10 is 4ohms. The back of the 4x10 has two 1/4" male jacks hard wired to the speakers that go to the amp. I had the 4x10 and the 15 hooked up at a low volume and the amp was clipping. I am guessing the amp was seeing a 4+4+8 ohm load. How would i go about rewiring the 4x10 to a usable load? Also should I use a speakon connecter? Sorry for the rambling.

First thing -- that amp can handle a minimum of a 4 ohm load, and you were providing it with only 2.67 ohms. You will damage your amp doing this for any length of time, and as it's clearly the most valuable part of this particular chain, you don't want to do that.

I don't know what drivers the 410 cabinet has, but it presumably has 4 x 16 ohm speakers wired in parallel to provide a total 4 ohm load. This could potentially be re-wired to provide either a 16 or 64 ohm load, neither of which is particularly desirable.

You're kind of stuck with using either cab separately (which in all honesty, given the configurations you have, is far preferable to using them together -- see faqs on mixing driver sizes), or hunting around for a different cab or pair of cabs altogether (better still!). There's lots available second hand, and thousands of threads here on pretty much any cab you could possibly find.

+1 to the above, 4 ohm MINIMUM load, so you can use either/or, but NOT both.
