2 Ohm & 4 Ohm Speaker Configurations
Typically your loudspeakers and source-unit will operate on a 4 ohms configuration, providing output
power of around 45W per channel (this may vary depending on source-unit model) and a maximum of
4x speakers (2x pairs) connected to the source-unit.
A 2 ohm configuration is achieved by doubling the number of speakers on each channel, allowing
a maximum of 8x speakers (4x pairs) to be supported and providing an increased output power of
around 72W per channel (this may vary depending on source-unit model).
While using a 2 ohm configuration increases the overall output power of the system the downside is
a slight loss in fidelity. You may decide the loss of fidelity is negligible and the higher output power is
preferred if using your Aquatic AV audio system where background noise levels are high, such as on
a boat, spa/hot tub or vehicle. Alternatively, if audio quality is preferred, and background noise levels
are low, the 4 ohm configuration may be more suitable.
4 Ohm Wiring Example
2 Ohm Wiring Example
4 Ohm Configuration
• Total output power 180W (4 x 45W)
• provides maximum fidelity
• 4 x speakers max. (1 x per channel)
• ideal for standard installations.
2 Ohm Configuration
• Total output power 288W (4 x 72W)
• fidelity is compromised slightly
• 8 x speakers max. (2 x per channel)
• ideal for installations with high background noise levels.
