DSP Amps

DSP-amplifier combo units combine multi-channel amplification and full digital signal processing in a single compact box — the most space-efficient way to add both power and proper tuning capability to a motorcycle audio system. Rather than running separate amplifier and DSP units with a cable between them, a DSP-amp integrates both functions, simplifies the install, and reduces wiring complexity.

The Hertz H8 DSP Amplifier is the most widely used DSP-amp in Harley audio builds — a four-channel Class D amplifier with full parametric EQ, time alignment and crossover on each channel, controlled via PC or mobile app. Cicada Audio's FLX DSP series offers similar functionality tuned to the Cicada speaker range. Both are sized for motorcycle installation and carry the input sensitivity range needed to work with Boom! Box GTS head units.

A DSP-amp is the correct choice when you want a complete upgrade in a single install — power, control and tuning without running two boxes and the cable between them. If you're comparing specific models, call us — the right choice depends on your speaker configuration and how much tuning flexibility you need. Ships Australia-wide and to New Zealand.

A DSP amplifier combines amplification and digital signal processing in one unit — the practical choice for motorcycle audio builds where mounting space is limited and both functions are needed. The DSP section handles time alignment, equalisation, and crossover functions per channel; the amplifier section drives the speaker loads.

Tuning a DSP correctly is the highest-impact single step in getting a motorcycle audio system sounding right on the road. Time alignment compensates for the non-ideal speaker positioning in a fairing; EQ compensates for the acoustic properties of the cabin and wind noise at highway speed. MAA recommends professional tuning for DSP installs to get the full benefit of the hardware.
