SounDigital Motorcycle Amplifiers
SounDigital for Harley-Davidson Touring
SounDigital is a Brazilian amplifier brand with a strong reputation in high-output mobile audio for compact Class-D amplifiers with published RMS output ratings at stated impedance and supply voltage. On a Harley, where space and charging are limited, that combination of real output and a small chassis is exactly what a demanding build needs. SounDigital suits the rider chasing serious, clean power without a large amplifier footprint.
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.
What to Know Before You Choose
- Published RMS ratings: output rated at stated impedance and supply voltage, so you can match the amplifier to the system.
- Compact Class-D: high output in a small chassis, typically with less heat and current draw than a similarly powered Class-AB amp.
- EVO PS range: mono and four-channel models from 800 to 2400 watts.
- Optional tuning control: the separately sold HKI Mini DSP adds crossover, EQ, level and time-alignment control.
- Australian stock and support: local stock, warranty handling and advice based on Australian Harley builds.
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 the DSP.
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.
