Installation

Plan your amplifier mounting location and wire routing in the bike. You will need to secure the amplifier in a location that is not directly exposed to water. The RZA 500.2 amplifier is designed for humidity and extreme outdoor temperatures but is not designed for submersion in water.

The inside structure of a Harley fairing is not waterproof. The fairing is designed to channel water away from the electronics inside the fairing. Take this into consideration when deciding on an amplifier mounting location.

Power Connections

8 Gauge cables should be used and run directly to the battery terminals. Never ground the amplifier to the frame or any other chassis ground point.

Always fuse the amplifier within 18 inches of the battery with a 30 amp fuse and a fuse holder that is designed for automotive/motorcycle conditions. The fuse holder should be easily accessible without the need for any special tools. Never place the fuse holder in an area that will not be accessible in an emergency.

Be sure that all power connections are secured in a way that will not allow them to pull or vibrate loose. Be sure that there is no exposed wire at any of the connection points. Take care that all cables are kept away from any moving or hot parts of the bike.

Remote Input Connection

If using the remote input to trigger the amplifier, be sure that your remote circuit is properly connected to other items in the system. For example: If using a DSP the remote input of the amplifier should always be connected to the remote output circuit of the DSP and never the bike’s accessory or the radio’s remote output.

In the event that you experience a turn-on pop after installation, and you are using a high level input first inspect your remote turn on configuration. Then you can try switching the amplifier to DC detect mode. DC detect mode will oftentimes cure turn-on pops because the amplifier will not turn on until after an audio signal is present.

Connect the Audio Input

The RZA500.2 is designed to accept any analog audio signal from an aftermarket, factory radio, or DSP. If using a speaker-level signal you will need to convert your speaker type connections to an RCA type connector. We recommend one of the many solutions available from www.AmericanHardBag.com.

Always Flash Factory Radios

Whenever using a factory radio the radio should always be flashed before adding aftermarket speakers and amplifiers. For more information visit: Ultimate Harley Radio Flash Guide

Connect the Speakers

The RZA500.2 amplifier is designed to drive speakers as low as 2-ohm when in stereo mode or a single 4-ohm speaker when in bridged mono mode. Never connect a speaker or combination of speakers that sum to less than 2-ohms in stereo mode or 4-ohms in bridged mode. Never allow any of the amplifier speaker outputs to come into contact with chassis ground or to be shorted to each other.

Attention!

Always verify that speaker polarity is correct before connecting the speakers to the amplifier by using a D-cell battery to activate the speaker. This should be done at the speaker lines where they make connection to the amplifier with the speaker lines disconnected from the amplifier. This will verify that polarity has not been accidentally flipped in a connection elsewhere on the bike. You should always do this no matter how sure you are that you got all of the connections right.

Before Making Any Settings

• Not a battery tender
• A fully charged battery is no good
• Do not tune the bike while it is running

It is imperative that you are able to simulate a charge cycle while tuning your audio system. Otherwise, gains and many other settings will be invalid and your tune will change while riding the bike.

Tuning & Settings

1. Turn the gains all of the way down
2. Set your crossovers to high pass if not using a DSP, or to flat if you are using a DSP
3. Play test tracks to determine each speaker’s phase relative to all other speakers. More info here
4. Set equalization for all channels if you have a DSP
5. Set amplifier gain
