Amplifiers – Street Glide & Ultra 2014–2023

Amplifiers for the 2014–2023 Street Glide®, Electra Glide® and Ultra Limited on the factory Boom! Box radio. Many connect to non-amplified Boom! Box systems through high-level inputs and switch on from the audio signal, without a radio flash.

Compact amps usually fit in or around the fairing, while larger amps may need saddlebag or remote mounting. Factory-amplified CVO and Boom! Stage bikes may need extra integration, so check your audio package first.

The amplifier follows the speakers, not the other way round.Channels, power and impedance depend on the positions you're driving. Tell us your model and year and we'll size it as part of a complete build.Build your system →

How do you choose an amplifier for a 2014–2023 Street Glide or Ultra?

Choose by channels and power. A four-channel amplifier can run front and rear pairs or other multi-speaker layouts. A two-channel normally powers one stereo pair, or both channels can be bridged to power one compatible mono load. A monoblock is intended for a subwoofer or other dedicated mono load. Match the amp to the 2Ω or 4Ω speakers you run. Class-D efficiency reduces heat and current demand compared with a similarly powered conventional analogue design, though location, airflow, impedance and load still matter, and the higher-output models draw enough current that a charging review is worth doing.

FAQ

Will these amplifiers work with my factory Boom! Box radio?

Most Cicada FLX amplifiers accept high-level factory-radio signal and offer VOX, DC-offset or remote turn-on, so they integrate with many non-amplified 2014 to 2023 Boom! Box systems without a reflash. Factory-amplified configurations, including some CVO and Boom! Stage setups, may need additional integration, so confirm your exact factory audio before ordering.

How many channels do I need?

A four-channel amp runs front and rear pairs or other multi-speaker layouts. A two-channel runs one stereo pair, or both channels bridged into one mono load. A monoblock is for a subwoofer. Many builds run a four-channel for speakers plus a mono for the sub.

Do I need a charging upgrade?

Sort the power and ground wiring first. Depending on the amplifier load, your listening habits and the bike's electrical condition, a higher-capacity battery, upgraded charging components or both may be appropriate. A lithium battery alone does not increase stator output, so plan the charging system to suit the draw of a high-output build.

Where does the amplifier mount?

Compact amps can mount in or around the fairing with the right hardware. Larger four-channel and mono subwoofer amps often mount in a saddlebag or another remote location. Check the dimensions against your intended location before ordering.
