i'm using current source method.
i've measured both drivers having an Re of 7.6 ohms.
my test resistor has a resistance of 10.3 ohms rated @ 10.
the problems start when i try and get a steady output from the amplifier to the driver to start measuring. i've tried 3 amps and none seem to be able to hold a steady voltage at any given frequency.
amps tried, 2x sure electronics tripath's and 1 sony thing.
i've tested the output voltage on the power supply for the sure amps and its a rock steady 24v.
what am i doing wrong? is my signal generator (sound card) to blame for not hold a steady tone, or am i doing something ridiculously stupid?
soundcard is a creative X-fi platinum, I have some on board realtek i could also try should this be considered the problem. the tone was produced via a program called audacity, could this be the problem?
and yes i know the drivers aren't hooked up to the circuit.

An externally hosted image should be here but it was not working when we last tested it.
