The EP 2500 at 4 ohm bridge is 2400 watts!! that's maybe too much for one sub.:holycow:
It'll never put out close to 2400W though.

You can guess on what 2 ohm/ch or 4 ohm bridge mode power is. Since this is an
amplifier based on a conventional power supply, don't expect power to double
when impedance is cut in half. I would estimate ~1800W RMS bridged
mode @ 4 ohms only if your AC line is a constant 117VAC, but this won't happen in
reality. If you did an RMS test on that amp, expect AC line sag. I'd probably
estimate 1200w - 1400w as the real power offered by EP2500 using 1% THD+N,
20hz sine wave test, less than the advertised 2400w.
