Just curious I know a lot of us use them and would be interesting to see some real numbers!

Stinger SPX 700.4 (175W @ 2 ohm; 125W @ 4 ohm)
2 ohm: ~153Watt
4 ohm: ~77Watt

Since I'm not the OP, I'll provide my setup as well:
All measurements taken with a Fluke 193-204 oscilloscope with the bike running.

2017 Street Glide, running, 14.2-14.4 V-rms
Sony XAV-AX7000: 2.72 V-rms pre-amp (did a bench test of this as well: 96% volume, or 48/50, gives distortion-free signal with 1 kHz @ 0dB test tone)
Test tone: 1 kHz @ -5dB

When you did the test on the amp did you have a load on the output or were the output channels open?

Open... I'm guessing that I should have had a load?
