The Alloy series amplifiers feature some technology and features that you will not find anywhere else including options right out of the box to connect to a factory or aftermarket radio source. The included HA-EASY adapter allows you to easily splice into factory wiring to acquire the audio input signal. Another common problem with using a factory stereo is finding a switched 12 volt wire to turn the amplifier on and off. Our Alloy Amplifiers feature a solution where the amplifier can be controlled via DC voltage offset or the traditional 12 volt switched remote turn on lead. Our Alloy amplifiers are also designed for maximum power output! All of the mono block class D amps are 1 Ohm Stable and feature similar power output at a 2 Ohms. This gives you tons of flexibility for woofer options and wiring configurations. The Class D circuitry also keeps the amp running cool with maximum power efficiency. All single and 5 channel models also include a bass remote to allow you to dial in the bass from the comfort of the driver's seat! Included HA-EASY Adapter = Easy Install All Harmony Alloy amplifiers include HA-EASY adapter(s). If installing an aftermarket radio source that has RCA output then the HA-EASY is not going to be needed for your installation. If you are connecting to a factory audio source this adapter is going to make for a much easier installation. The adapter has two purposes: When used with a factory stereo it allows you to splice into the vehicle factory speaker wires to acquire the audio signal It will also turn the amplifier on and off without a traditional 12 volt switched remote wire in most applications. It's possible to generally find your factory speaker wires 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 saving a ton of installation time and saving money on costly adapters. Daisy Chaining a 2nd Amp or Accessory Next up is a feature you will not find on any other brand or model of amplifiers and we are very proud of this! So 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 also want 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. The sky is the limit of what this could be used for and can be anything you want to be turned on or off with your music. Dialing in Your Harmony Amp The wiring is done, the subwoofers are connected, and all that is left is setting up the controls on the amplifier. Most other brand amps want 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 than just be easily adjusted by just 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 quick and easy setup knobs.

If you need an order by a specific date we recommend you call us at 1-877-275-4434 Shipping Policy Although many orders are shipped the same day that we receive them, due to a variety of factors it can take up to 24 hours to process your credit card information and ship your order. FedEx picks up shipments daily, Monday through Friday around 4:00 PM (Eastern Time). They DO NOT operate on weekends or holidays. If you place an order for shipping on Friday night, the next available shipping day is Monday. Transit time depends on where you are located and which warehouse we ship your order from.

Weekend and holidays are not counted as transit days. Example: If you place an order Friday evening for 3-Day Select shipment and the following Tuesday happens to be a holiday, your order will be processed for Monday shipment. Since Tuesday is a holiday, the first transit day is Wednesday, the second transit day is Thursday and the final transit (and delivery) day is Friday. It is important to understand this scenario for all expedited shipment methods.
