Harley Amplifier, EQ, and Harness Power Combo

$719.97 $639.99

Save Big and Get the Best Audio Performance with This Amplifier & DSP Combo Package

This is a killer package for adding a powerful four channel amplifier to any Bagger. This kit addresses all of the common issues with adding an aftermarket amplifier to a modern Harley Davidson, Indian, or Victory with a factory radio. This kit also works perfectly with aftermarket radios as well.  

Fitment: All Baggers with fairings.
We also have a version of this kit that has been designed specifically for Road Kings. Call for info 1(888) 311-0016

What You Get:

  1. Diamond Audio Micro4V2 600 Watt 4 Channel Amplifier
  2. Rockford DSR1 Bluetooth Digital EQ
  3. Premium 8 Gauge Plug & Play Power Kit for Fairing Mounted Amplifier


  • EQ is programmed by Bluetooth using a free app on your smartphone.
  • Very simple user friendly setup!
  • Includes a 31 Band EQ for each speaker (up to 8 channels) with speaker level inputs or line level RCA and 8 channels of RCA outputs (front, 2nd front, rear, and sub).  
  • 600 watt Diamond Audio Micro4V2 amplifier included. 
  • Premium OFC 8 gauge power and speaker wire kit included for mounting the amplifier in the fairing. 
  • Velcro mounting pad for amplifier included


This kit takes 2 or 4 channels of signal input but outputs 8 channels (front 1, front 2, rear, sub). The EQ app is simple to use and does a spectacular job of dealing with the factory radio's built in EQ curve that does not sound good with aftermarket equipment on its own.  

The included power harness is 100% OFC Copper and not that Aluminum junk. A waterproof Mini ANL fuse holder is included and already installed on the harness along with chrome battery ring terminals and braided nylon wire loom. This is a very nice power kit.

If you plan to use this kit with a '14 or newer Harley factory radio, we make a plug and play harness for that. You can find it here.
