1. Safety Information
Please read all instructions carefully before installing and operating your Memphis Audio PRX1000.1V2 amplifier. Failure to follow these guidelines may result in damage to the amplifier, speakers, or vehicle, and may void your warranty.
- Professional Installation Recommended: For optimal performance and safety, professional installation by an authorized Memphis Audio dealer is highly recommended.
- Power Source: Ensure the vehicle's battery is disconnected before making any power connections to prevent electrical shorts.
- Wiring: Use appropriate gauge wiring for power, ground, and speaker connections as specified in this manual. Improper wiring can lead to overheating and damage.
- Mounting: Mount the amplifier securely in a dry, well-ventilated area, away from direct sunlight, heat sources, and moisture. Ensure adequate airflow around the amplifier.
- Volume Levels: Prolonged exposure to high volume levels can cause hearing damage. Always listen at moderate levels.
- Grounding: A proper ground connection is crucial for amplifier stability and performance. Connect the ground wire directly to the vehicle's chassis, ensuring a clean, paint-free metal-to-metal contact.

3. Installation Guide
Proper installation is critical for the performance and longevity of your amplifier. If you are unsure about any steps, consult a professional installer.
3.1. Mounting Location
Choose a mounting location that:
- Is dry and free from moisture.
- Allows for adequate airflow around the amplifier to prevent overheating.
- Is secure and protected from physical damage.
- Is not exposed to direct sunlight or excessive heat.
Common locations include under a seat, in the trunk, or behind a panel.
3.2. Wiring Connections
Before making any connections, disconnect the vehicle's negative battery terminal.
Figure 3.1: View of the power and speaker output terminals on the Memphis Audio PRX1000.1V2 amplifier. This side features connections for GND (Ground), REM (Remote Turn-On), +12V (Power), and Speaker Out.
- Power Connection (+12V):
Connect a heavy-gauge power wire (e.g., 4 AWG or larger, depending on total system power) directly from the vehicle's positive battery terminal to the +12V terminal on the amplifier. Install an appropriate fuse holder (rated for the amplifier's current draw) within 18 inches (45 cm) of the battery.
- Ground Connection (GND):
Connect a heavy-gauge ground wire (same gauge as the power wire) from the GND terminal on the amplifier to a clean, solid metal point on the vehicle's chassis. Ensure the contact point is free of paint, rust, or dirt for an effective ground. The ground wire should be as short as possible, ideally less than 3 feet (1 meter).
- Remote Turn-On (REM):
Connect a remote turn-on wire (typically 18 AWG) from your head unit's remote output (usually a blue/white wire) to the REM terminal on the amplifier. This wire signals the amplifier to turn on and off with your head unit.
- Speaker Output (SPEAKER OUT):
Connect your subwoofer(s) to the SPEAKER OUT terminals. This is a monoblock amplifier, designed for a single subwoofer or multiple subwoofers wired to present a 1-ohm load for maximum power. Ensure correct polarity (+ to + and - to -) for all speaker connections.
Figure 3.2: View of the input and control panel on the Memphis Audio PRX1000.1V2 amplifier. This side includes RCA Input/Output, REM/DC/Audio switch, Input Level control, and Remote bass control port.
- RCA Input (INPUT):
Connect RCA cables from your head unit's subwoofer pre-out (or full-range pre-out if no dedicated subwoofer output is available) to the RCA INPUT terminals on the amplifier.
- RCA Output (OUTPUT):
The RCA OUTPUT terminals allow you to pass the audio signal to another amplifier in a multi-amplifier setup.
- Remote Bass Control (REMOTE):
Connect the included remote bass level control to the REMOTE port. This allows for convenient adjustment of the subwoofer level from the driver's seat.
4. Operating Instructions
4.1. Initial Power-Up
After all connections are made and verified, reconnect the vehicle's negative battery terminal. Turn on your head unit. The amplifier should power on, indicated by an illuminated logo or power indicator.
4.2. Adjusting Input Level (Gain)
The INPUT LEVEL control (often referred to as gain) matches the amplifier's input sensitivity to the output level of your head unit. It is not a volume control.
- Turn the amplifier's INPUT LEVEL control to its minimum (fully counter-clockwise) setting.
- Set your head unit's volume to about 75-80% of its maximum level.
- Play a dynamic piece of music with strong bass content.
- Slowly increase the INPUT LEVEL control on the amplifier until you hear distortion, then back it off slightly until the sound is clean.
- Avoid setting the gain too high, as this can lead to clipping and damage to your subwoofers.
4.3. REM/DC/Audio Switch
This switch controls how the amplifier turns on:
- REM: The amplifier turns on via the remote turn-on wire from the head unit. This is the standard and recommended method.
- DC: The amplifier senses a DC offset on the speaker-level inputs (if using a line output converter or high-level input) and turns on automatically.
- Audio: The amplifier senses an audio signal on the RCA inputs and turns on automatically.
For most installations with an aftermarket head unit, set this switch to REM.
4.4. Remote Bass Level Control
The remote bass control allows you to adjust the subwoofer output level conveniently from the driver's position without needing to access the amplifier directly.
5. Maintenance
The Memphis Audio PRX1000.1V2 amplifier requires minimal maintenance to ensure long-term performance.
- Cleaning: Periodically wipe the amplifier's exterior with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Connections: Annually check all power, ground, remote, and speaker connections to ensure they are secure and free from corrosion. Loose connections can cause intermittent performance or damage.
- Ventilation: Ensure that the amplifier's cooling fins are not obstructed by debris or other objects to maintain proper heat dissipation.
