Easy Install Adapter

All Harmony Alloy amplifiers include HA-EASY adapter(s). If installing an aftermarket radio source that has RCA output then you won’t need the easy install adapter. However, if you’re trying to hook up your amp to a factory radio this is when our HA-EASY adapter comes in handy.

It serves two purposes:

• Allows you to easily splice into vehicle factory speaker wires to acquire the audio input signal

• Turns the amplifier on and off without a traditional 12 volt switched remote wire in most applications

The factory speaker wiring in your vehicle might be hidden in a kick panel, in a wire pack under threshold trim or even at the speaker location itself. The factory radio does not need to be removed which will save you time on installation and money on costly adapters.

Remote Amp Bass Controller

All single channel models include a bass remote to allow you to dial in the bass from the comfort of the driver’s seat! The remote bass knob is designed to mount near the driver for quick and easy fine tuning based on music type. This is especially handy if you listen to a wide variety of music as bass frequencies can widely vary from musical styles. The remote bass controller features a 0 to 12 dB boost range. It can completely cut out all output on the amplifier which is handy for system setup. The remote also features a blue LED status light so you can easily tell if your amplifier is on. All installation mounting hardware is included.

Level Up and Chain a 2nd Amplifier or Accessory

This feature you will not find on any other brand or model of amplifiers and we are very proud of this! Let’s say you have a factory radio and you are running one of the Harmony amps using the included HA-EASY adapter but you also have a 2nd Harmony amp you’d like to install or maybe even an amp of a different brand.

When the Harmony amp is being controlled by the DC offset to turn it on and off, the empty remote terminal now becomes a 12 volt switched output! This can be used to turn on and off the 2nd amplifier or any other 12 volt switched accessory! This output is only designed to turn the device on and off via a low amperage trigger and rated at 1 amp maximum. We’ll let you figure out what this could be used for turning on and off with your music.

Your Comfort Is Our Priority

Once you hooked everything up, and all that is left is setting up the controls on the amplifier, you want it to be quick and easy, so you could wrap up and enjoy the music.

Most amps require you to go dig for a hex key or a small screwdriver to dial in your settings. The Harmony Audio Alloy amps include metal adjustment knobs that do have a slot for fine tuning but also are large enough to be easily adjusted by your fingers. This may not sound like that big of a deal but trust us when the amp is installed under a seat or on the cab of a truck you are going to appreciate it!
