Over the last few days I was home and able to run a couple tests with my gear. I was pleasantly surprised to see these numbers when I clamped my pair of SAZ-1500Ds strapped at 2 ohms (1-per), car on with factory alt, off of a little 600CA battery: ~3,100WRMS I built my first attempt at a box strictly geared towards SPL, and after tinkering with it a bit worked up to a score of 146.0 dbdrag style, using these amps and two 12" RE SXs out of a saturn trunk. Just figured I'd share the results... I have big plans for this summer once I get a hold of a new battery and some time to build/test.
