Which amp Nady 850 or Behringer 500or Alesis RA500

I need a new amp to power my new subs. I have built the RE 15" sub and am building a shiva-x sub. Which of the 2 amps are better for my subs? The Nady is 190 both 500's are 160. Can one of these amps power both subs?

I'm using a Behringer A500 bridged to power my Kappa Perfect sub and it barely breaks a sweat. It can easily hit 100 dB (sorry neighbors!) and according to the Behringer meter could get to 120+ dB before running out of juice. If either of those subs is 8 ohms, the Behringer would work nicely.

I couldn't find much info on the Nady and what I did find was confusing. I don't think I would trust it based on the limited info I was able to dig up. The Alesis is spec'd very similar to the Behringer, so it will more than likely perform similar to my A500.

The Shiva sub is realistically 4 ohms, so I would look into a Yamaha P series or Behringer Europower amp. None of the amps you listed can provide more than a couple hundred watts into 4 ohms. If you want to do both subs, the Behringer EP2500 is probably your best value, since it is stable down to 2 ohms (which would give you the most output from your RE 15)

You may as well get an EP2500. Don't go cheap here. Get what you need to drive the subs.

If you need a good deal then look for used QSC amps.
