Hogtunes NCA 450-RM : 4 Channel Amplifier / 4x50 watts (2014 - model year) - Manual (Page 3)

Thank you for choosing the Hogtunes NCA 450-RM Amplifier for 2014+
Rushmore Platform Bikes. Since positive word of mouth is the best way to
grow our business, we want your new system to work as well as it was
designed to. If you have any questions or concerns, we are here to help.
IMPORTANT: The NCA 450-RM makes its
best power when powering 2 ohm (Ω)
speakers. Running higher impedance
speakers (3, 4, 6 or 8 ohm) will reduce
the amplifier’s power output!
The NCA 450-RM is rated for 50 watts per channel using 2 ohm speakers
at 14.4 volts at 1% Total Harmonic Distortion (THD). Although this amplifier
makes its highest power with 2 ohm speakers, if Hogtunes 5.75 ohm speakers
or 4 ohm car speakers are used there will still be a noticeable improvement
in volume and sound quality.
If you are not using Hogtunes speakers, chances are the speaker connectors
are not the same as stock. If you need to change connectors, please note that
on all Hogtunes products, the smaller connector (black wire) is positive (+).
