SounDigital Motorcycle Amplifiers

SounDigital is a Brazilian amplifier brand with a strong reputation in high-output mobile audio. For Harley-Davidson® Touring we carry its compact EVO PS mono and four-channel Class-D amplifiers, from 800 to 2400 watts, and the HKI Mini DSP. It suits riders building a demanding system who want serious power from a small chassis.

2024 and newer Skyline OS bikes need a compatible A2B interface before an amplifier can connect.

Where does SounDigital fit in a Harley audio system?

This collection carries compact SounDigital EVO PS mono and four-channel amplifiers from 800 to 2400 watts, together with the HKI Mini DSP for crossover, EQ, level and time-alignment control. Match the amplifier to your speaker impedance and channel count, a four-channel amp for the speaker stage and a mono amp for a subwoofer, and add the HKI Mini DSP where you want full control.

FAQ

What makes SounDigital different?

Compact Class-D amplifiers with published RMS output ratings at stated impedance and supply voltage, so you get real output in a small chassis that suits a motorcycle's space and charging limits.

Which EVO amp do I need?

Match the amplifier to your system: a four-channel model for a multi-speaker stage, or a mono model such as the PS 800.1 or PS 2400.1 for a subwoofer or suitable mid-bass load. Tell us your speakers and we will size it.

Do I need the HKI Mini DSP?

Not for a basic build, but the HKI Mini DSP adds crossover, EQ and time alignment for a tuned result. See our digital signal processors.

Will it fit on my bike?

SounDigital EVO amps are compact, but check the dimensions of the higher-power models against your mounting location. Tell us your bike and we will confirm.

Not sure what fits? Tell us your year, model and current audio setup and we'll confirm the parts before you order, or contact Motorcycle Audio Australia.
