I've currently got two Gemini GVX1500 speakers and a Behringer EP2000 amp. I've ordered two Peavey Messenger Pro-SUB Subwoofers.
Stupid question time, will I need a second amp and have to run it in mono mode or will the amp cope as it is?

Hi Rothgar
i have been looking at the amp and speaker system and initially your amp will power that lot together
The amp spec is as folows - 2 x 1,000 Watts into 2 Ohms; 2 x 750 Watts into 4 Ohms; 2,000 Watts into 4 Ohms (bridge mode)
The peavey subs have a special crossover so no matter what you plug into the high output the total load the amp will see will be 4Ohms
From the peavey site
Hi output
We have equipped the Pro™ Sub with a high pass output socket. This provides a filtered output signal for operating a satellite enclosure
with a minimum impedance of 4 ohms. Enclosures such as the Pro 12/15 are recommended. The design of the crossover ensures the
total load presented to the power amplifier is never less than a nominal 4ohms.
the rms of the sub is 300w and the geminis are 300 too (is that right - cant find the spec) which gives you 600w per side. as you amp will deliver 750w per side at 4Ohm then you will be in business.
However to get the best from the system, and it will make a big difference - i have done and A/B on this one, a second amp with a proper external crossover is the best option (the crossover will let you run in full stereo mode). Saying that have a look at your mixer. you may have a sub output or a booth/second main output facility which will do away with the crossover and you send a full signal to both amps and on to both sets of speakers
Using a sub either side with the geminis as mid top satellites is the easy option but you need a dedicated lead to go from the sub to the geminis
From the peavey site
A dedicated lead with a 1/4” Jack
plug or Neutrik™ Speakon at each end is required to connect the hi output from the Messenger Pro™ Sub to the input of the satellite.
If i remember right i had a speakon lead that was wired +2 -2 at one end and +1 -1 at the other
hope all this helps

Thanks for the advice Dave, my mixer is a DJM 5000 which does have booth output so that's an option for the future.
The speakers are Gemini GX1500s, not GVX as I originally put.
