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.

Rewiring a Behringer 4x10

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.

@KWthewanderer, wcriley speaks the truth. You misunderstood the manual. It shows how to wire four 4 ohm speaker/CABINETS for 8 ohms total load of four speaker cabs. If your speakers were all parallel wired and you had it rewired for series/parallel you just made a 16 ohm cab (loss of volume over other cabs from a SS amp). An "ohm meter" does not measure AC speaker nominal impedance, they can only measure DC resistance. AC impedance (that speakers are rated for) is a different parameter than the DC resistance of the voice coil (such as a battery would supply, not a musical instrument).
[Invalid or Expired Link Removed] they were either too cheap or too lazy to draw their own graphics for the manual and used internet stock "SPEAKER wiring" graphics instead of drawing the diagram showing speaker CABINENTS.

Ignore the graphic. Look at the chart in Figure 4.1, which shows that the only way to end up with an 8 Ohm load is to start with 8 Ohm drivers.
Sheesh. Bad manuals suck. At least try to buy copyright on something like
tobias rocks!alright guys, be honest. what do you think?
alright then, I will amend my post to reflect the opinions of the others.
No big deal, you want corrections made if you made a statement in error. The manual is the fault from what was said.
guess a girl can't even admit to being horribly wrong,
and gracefully bow out without garnishing the snarky final death blow...
Oh well, I still love "Talk Bass Dot Com"
around here we are a bit sensitive when it comes to facts vs opinions being stated as facts. So much of that happens and it must be struck through with a garlic laced silvered timber stake and burned every time.
Now you've been reprimanded twice. You only get one more. Just sayin'
Actually you got off easy. No one posted a zombie pick!
Now you fella's quit pickin' on girls and move on. Go on. Nothing to see here. Not unless someone posts a zombie pic.

I love a challenge!
Riis
and another...
Meh. She got some dud advice from someone she trusted. Probably still in need of some good advice.
