Here are the specifications and descriptions for the stock amp:
STEREO 15W (4 Ohm) CLASS-T™ DIGITAL AUDIO AMPLIFIER
USING
DIGITAL POWER PROCESSING™ TECHNOLOGY
Sonic Impact introduces the first totally portable am capable
of generating 15W per channel output from a fully battery operated source that
fits in the palm of your hand and weighs less than one and a half pounds.
Ideally suited for powering the SoundpaX speaker line by Sonic Impact. In stock
March of 2003.
GENERAL DESCRIPTION
The TA2024 is a 15 W/ch continuous average two-channel Class-T Digital Audio
Power Amplifier IC using proprietary Digital Power Processing™ technology.
Class-T amplifiers offer both the audio fidelity of Class-A/B and the
power efficiency of Class–D amplifiers.
