About the design
The E series amplifiers are based on the latest Texas
Instruments class D controllers. This amplifier topology is
the foundation for some of the world's most efficient
amplifiers. We took the typical Class D design, improved
on it and made it suitable for car audio in all vehicles with
sensitive electronics by using very high quality inductors
and additional EMI filters for improved distortion,
frequency response, clipping characteristics and reduced
EMI compared to many (most) competitors Class D
offerings.
The power supply and the output stages use multiple N-
Ch MOSFETs for efficiency and robustness
Heat from the MOSFETs is removed by mounting them to
an extruded aluminum heatsink. Extruded aluminum is
superior to cast aluminum for heatsink applications as the
extrusion process all but eliminates air pockets and voids
that are common with cast aluminum heatsinks.

Mount it
When an amplifier is mounted in a car that is going 50
MPH and crashes the amplifier might continue traveling
at 50 MPH and cause destruction and/or bodily injury if
proper mounting techniques are not used. Use #6 or M3
screws in each of the mounting tabs to mount this
amplifier to something very secure in the vehicle. The
bottom plate is also electrically grounded, so it is best to
mount it to something NOT grounded to avoid ground
loops.
