HM-300A Amplifier Power Harness for Aquatic AV AD300.2 (8 AWG)

The HM-300A Amplifier Power Harness is purpose-built to power the Aquatic AV AD300.2 amplifier in a saddlebag with a clean, reliable battery connection.

We spec UL 1015 wire in 8 AWG (intentionally overbuilt) to keep voltage drop low and performance consistent under real riding conditions. The harness has ring terminals on power and ground for a secure connection at the battery, inline fuse, and with the correct length to route cleanly from the battery to the saddlebag.

At the amplifier end, it uses the waterproof HRB connector used by Aquatic AV amps, with the terminal already crimped on. For easier installation, the connector body is packed separately so the lead can be fed through the included grommet into the saddlebag first then the connector is assembled and plugged into the AD300.2 for a clean, watertight finish.

Component Notes

8 AWG UL 1015 power/ground conductors (overbuilt for low voltage drop)

Inline 50A fuse located approximately 10 cm from the battery for protected, serviceable power.

Battery ring terminals for solid power + ground

Correct length: battery to saddlebag amplifier location

Waterproof HRB connector compatible with Aquatic AV amp plug

Connector body packed separately for easy routing through supplied grommet, then final assembly at the amp. Grommets are included for both 2013-earlier and 2014-later saddlebag panel thicknesses.
