Hifonics TPS-A500 Powersports Amplifier
Before you start
CAUTION: Many new and factory radios require a reset code when disconnected from battery power. This is an anti-theft feature. Before unplugging power, you must determine if your radio/source unit requires a reset code. Check the operation manual for your vehicle or contact the dealer.
Power cable size and fusing
- It is critical to use the proper power and ground cable. Select the size listed here for your amplifier model. Always use high quality copper cable. Visit our website for multi amp system cable recommendations.
- Be sure to use the proper fuse size for each model. Some models require an external fuse.
Installation
-
Disconnect Negative Battery Terminal. Place terminal in a secure position so that it won’t accidentally contact the negative battery post
-
Run Cables: Properly route power, speaker and RCA cables through the vehicle.
-
Mount Amplifier: Choose a mounting location that will provide adequate air ventilation. Mount the amplifier to a secure surface. Do not mount the amplifier upside down.
-
Chassis Ground: The chassis ground connection is critical to the performance of the amplifier. Choose a location that is close to the amplifier. Completely scrape away the paint and use a nut and bolt if possible.
DO NOT USE AN EXISTING FACTORY BOLT! -
Power Connection: Attach the chassis ground, +12V and remote wire. It is important to make sure these connections are very secure.
-
Signal Input Connection: Connect the RCA cables to the INPUT connectors. The OUTPUT can be used to provide input for a second amplifier.
-
Gain Control: Turn the GAIN control completely counter-clockwise to minimum.
-
Speaker Connections: Connect the speaker cables to the speaker output connectors. Follow the diagram below that best fits your speaker configuration.
-
Positive Battery Connection: Connect the power cable to the positive battery terminal. The power cable must be fused within 18 inches of the battery terminal.
Be prepared to disarm your vehicle’s alarm and to enter your radio / source unit code. -
Re-connect Negative Battery Terminal: Re-connect the negative battery terminal making sure it is securely tightened.
Setup
Settings
The illustrations below describe the various controls. Refer to the illustration that matches your amplifier.
- GAIN Adjustment: The gain control purpose is to match the output of your source signal to the amplifier. Refer to the section B below for detailed instructions.
- X-OVER Switch: This switch will set the amplifier to have a full frequency output or to filter out high or low frequencies. The NA1-400.2 offers either a bandpass or a high pass filter.
- Frequencies Adjustment: The Low Pass Filter will cut off the frequencies above the setting. The High Pass Filter will cut off the frequencies below the setting.
- SUBSONIC Adjustment: The Subsonic Filter will cut off the frequencies below the setting. If using with a subwoofer the settin should be kept between 15-25Hz.
- BOOST Switch: The Boost Switch will increase the signal 12dB at 45Hz. Be aware this setting can cause distortion if the gain is not set properly.
Level Setting
This is a critical step to insure your amplifier is properly adjusted to match the signal output level of your source unit.
THIS IS NOT A VOLUME CONTROL!
- If possible, with the source unit off, confirm that the primary volume control is turned down (counter clockwise).
- Turn on the source unit (CD, or MP3 player). Re-confirm that the volume is turned down. Make sure the source unit controls; balance, fader, bass and treble are all set to center or “0” adjustment. Make sure that the green LED on the end of the amplifier is illuminated.
- Play a clean musical selection of which you are very familiar. CD is preferred. Do not use radio signals for level setting. Hit play and start turning the volume of the source unit up.
- Stop increasing the source unit volume when you reach 3/4 (about 75%) or until you hear speakers begin to slightly start producing distortion.
- Increase the amplifier gain (clockwise) until distortion is heard, then back the level down (counter clockwise) until the distortion is eliminated. Small adjustments may need to be made to balance the levels of multiple amplifiers.
Remote Level Control
Some models include a bass remote. Avoid adjusting the bass remote while operating vehicle.

FAQs
What does the MARINE GRADE PROTECTION entail for the Hifonics TPS-A500.2 amplifier?
It means the amplifier is ABYC and ASTM certified, ensuring that it uses conformal coated PC boards that resist corrosion from salt spray and moisture.
What is the significance of the Low Noise Pre-Amplifier Stage?
This special preamplifier significantly reduces incoming noise from source units, resulting in dramatically improved sound quality.
What does Class D mean in the context of this amplifier?
Full Range Class D refers to a highly efficient circuit topology. This allows the amplifier to produce a lot of power while using a very small heatsink.
Can you explain the amplifier's diagnostic capabilities?
The amplifier features three-stage protection circuits that monitor thermal conditions, overload situations, DC levels, and speaker shorts. These are all indicated with lighted indicators on the amplifier's end panel.
How does the heat sink function?
The amplifier is equipped with a heavy-duty extruded aluminum heat sink that dissipates heat quickly. This helps prevent heat-related distortions and ensures consistent performance.
What makes this amplifier suitable for marine environments?
Apart from its marine-grade protection, the amplifier is also marinized or water-resistant, making it durable in various environments, especially those exposed to water or moisture.
Is the amplifier's wire harness fixed or detachable?
The Hifonics TPS-A500.2 features a detachable wire harness, which simplifies installation, especially in tight spaces. Once wired, you can simply plug it in.
What are the available input connections for the amplifier?
The amplifier accepts 1 pair of RCA nickel-plated inputs. These are high- temperature, impact-resistant with hex screw terminals for secure, erosion- resistant connections.
Can this amplifier support both stereo and bridged mono operation?
Yes, the amplifier offers flexibility in installation, allowing it to run in two-channel (stereo) or bridged mono mode.
What's the function of the impatico Coil Design?
The Simpatico Coil Design, which is a dual coil Pulse Width Modulated power supply, ensures that voltage remains constant through the Ultra-Fi output devices.
What materials are used for the amplifier's connections?
The connections are gold-plated, ensuring corrosion resistance, especially vital for longevity in marine environments.
Is this amplifier recommended for specific vehicles or applications?
The Hifonics TPS-A500.2 is versatile but is especially marketed for use in Polaris RZR, ATVs, UTVs, and carts.
