Frequently Asked Questions

A mounting bracket is something we recommend. We have several mounting kits available for the Road Glide Fairings and Batwing Fairings models.  You can also create your own customize mounting bracket; just be sure you can still fit your amplifier.

Side Note: Do not mount your amplifier directly on top of the stereo or the stereo’s mounting bracket. Why? Over time, you’ll damage the stereo with heat transfer. Also, you will void your warranty if you do so.

This product includes the following:

  • AQ-AD300.2-MICRO Amplifier

  • User/Installation Manual
  • RCA male-to-male Adaptor (x2)
  • Wiring Harness

  • High-Level Input Adaptor

Yes, the amplifier can be hooked up to both front and rear speakers!  This will require a little extra wiring.
