Precision Power – Amplifiers

The Precision Power ATOM MAA4-400, a compact four-channel Class-D amplifier for Harley-Davidson® Touring. Its four channels can run a front and rear pair or a bi-amplified front stage, and the small chassis suits tight spaces on a bike. It is the matched, value-focused way to power Precision Power speakers.

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

FAQ

How many speakers can the MAA4-400 run?

Its four channels run a front and rear pair, four speakers, or a bi-amplified front stage, depending on your wiring and speaker impedance. Tell us your speakers and we will confirm.

Will it fit on my bike?

Usually. The ATOM is a compact amplifier designed to fit tight motorcycle spaces. Check the dimensions against your intended mounting location.

Do I need this amp for Precision Power speakers?

Not necessarily this one, but a dedicated amplifier gives the speakers clean power to work with. The ATOM is the matched Precision Power option. See the Precision Power speakers.

Can I add a subwoofer?

A four-channel amp drives the speaker stage; a subwoofer normally uses a separate mono amp. See the Precision Power subwoofers, which include a powered option.

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.
