guesses:
you made a mistake in the implementation
you have a numerical or precision problem in your implementation
you have a high Q and some signal at the resonant peak.

I have a low pass filter implemented using biquadratic algorithim

However, when I have my cut off frequency much below 2kHz, the output
starts to get really loud (seemingly above 0dB on the AULab meters).
Any guesses?
