As with cars and trucks, speakers need a boost of power in order to improve the speaker volume and audio quality. Especially true when riding a motorcycle, with a loud engine and wind in your face, adding a solid motorcycle amplifier can make a world of difference. With that being said, follow these steps to install an amplifier on your own motorcycle. 

Required Tools (may vary depending on motorcycle or installation needs):

  • Screwdrivers
  • Wire Cutters
  • Wire Crimper and Stripper
  • Electrical Tape
  • Zip Ties
  • Amplifier Wiring Kit

1. Choose a Motorcycle Amplifier

Make sure to purchase an amplifier that is meant for motorcycles. These amplifiers will not strain your battery because they are manufactured to run at low load levels. They also are able to fit in tighter spaces due to their smaller compact chassis sizes. Many of these amplifiers use materials that are built to withstand vibrations and outdoor elements. 

When browsing our motorcycle amplifiers, be sure to also consider the power rating. This rating should be the same or very similar to the requirement of your particular bike for best performance. Lastly, determine where you plan on installing the amp to narrow down your choices.

2.Disconnect the Battery’s Negative Cable

To keep yourself and your electronics safe, it is always advised to disconnect the negative battery cable before beginning. Remove your seat to access the battery and unscrew or unbolt the negative cable from the terminal post. Doing so will prevent shorts, shocks, and other unwanted issues.

3. Mount the Amplifier

Depending on where you decide to mount the amplifier, you will need to gain access to that location. Many choose to mount the amp next to or on top of the stereo. In that case, the windshield and/or outer fairing will need to be removed to gain access to that area. If mounting under your seat, remove the seat to get started. 

Next, you will want to mount the amplifier using a mount plate bracket, zip ties, or similar hardware. Be sure that you have access to all necessary wiring before securing tightly.

4. Connect and Wire the Amplifier to the Stereo, Ground, and Battery

With the new amplifier in the correct location, you are now ready to wire the amplifier to the necessary components. As with any amplifier, the remote power and any RCA cables will run to the stereo receiver, the power wire will run to the positive terminal of the battery, and the ground wire to a grounding point. Always refer to your particular amplifier’s instructions for a wiring diagram to follow. 

5. Test out the Amplifier

Before you finish up, it is always a good idea to test everything out. Connect the battery and test out the stereo, speakers, and amplifier controls. Ensure that all components are working as expected. If not, now is the time to troubleshoot and make any changes or adjustments as needed.

6. Reassemble and Clean Up the Installation

Now, clean up all wiring using zip ties and run all wiring so that it will not be seen. Reassemble the outer fairing, seat, and any other parts that were removed (be sure not to crimp or pull any wires). Test out your handlebar steering by turning the front wheel to the far left and far right to ensure wiring has not caused any issues. 

By following the above motorcycle amplifier installation steps, along with your amplifier’s directions, you can have your amp installed in a few hours. Once completed, you can start enjoying a more powerful, crisp, and clear audio experience when cruising around. If you missed it, also be sure to check out our other motorcycle how to articles about installing replacement stereos or upgrading your speakers.
