Collection: Amplifiers

Powering speakers on a boat demands more than a standard car audio amplifier can reliably deliver. The options here range from compact two-channel units like the JENSEN JAHD240BT, which adds Bluetooth source input alongside its amplification, to heavy-output multichannel builds such as the DS18 HYDRO six-channel rated at 3000W. DS18's HYDRO line is built specifically for open-water exposure, with waterproof construction suited to helm and cockpit placement where spray is routine. Aquatic AV covers the middle ground with two, four, and five-channel configurations depending on how many speaker zones your system needs. Channel count matters most when planning your layout: a single wakeboard tower zone may need only a monoblock or two-channel amp, while a full cabin-plus-cockpit setup calls for four or five channels.

Before choosing, confirm the amplifier's RMS power matches your speakers' handling capacity and check the ohm rating compatibility. Class D designs, which most models here use, run cooler and draw less from your battery bank, an important consideration for boats without shore power. Think about mounting location too: flush-mount and surface-mount options differ in the space and depth they require behind the panel. DS18's NXL series and Aquatic AV units suit enclosed or semi-protected spaces, while the HYDRO line tolerates direct exposure better.
