Memphis PRX1500.5V2 5-Channel Car Amplifier

The Memphis PRX1500.5V2 is a five-channel car amplifier designed to power front and rear speakers along with a dedicated subwoofer from one chassis. It is suited to vehicle audio upgrades that need stronger speaker output and meaningful low-frequency support without adding separate full-range and mono amplifiers. Its channel layout supports a complete amplified system while keeping signal routing and mounting more straightforward.

For the four main channels, the amplifier delivers 75 watts RMS per channel at 4 ohms or 125 watts RMS per channel at 2 ohms. The dedicated subwoofer channel provides 400 watts RMS at 4 ohms, 700 watts RMS at 2 ohms, or 1,000 watts RMS at 1 ohm. This makes it a practical match for systems using efficient component or coaxial speakers plus a properly impedance-matched subwoofer.

The main channels can also be bridged to provide 250 watts RMS x 2 at 4 ohms, allowing the amplifier to support alternate system layouts. Independent front/rear and subwoofer tuning sections help tailor the output to the speakers and enclosure in use. Variable crossover controls help remove unnecessary low bass from smaller speakers while directing bass information to the subwoofer channel.

A compact extruded-aluminum heatsink manages the amplifier's physical structure, while the concealed top-mounted controls provide access to setup adjustments. The acrylic top cover and blue LED accent lighting give the amplifier a finished appearance without changing its core installation role. Selectable turn-on options and high- or low-level signal capability broaden compatibility with aftermarket or factory audio sources.

The PRX1500.5V2 fits well in a staged system upgrade when a single amplifier is preferred for both cabin speakers and bass. Its 1-ohm-stable mono subwoofer channel gives flexibility when selecting and wiring compatible subwoofers. A wired bass-level control is included for convenient adjustment of the subwoofer-channel level from the front of the vehicle.

Key Features

• Five-Channel Layout: Powers four speakers and one dedicated subwoofer channel from one amplifier.
• 1-Ohm Sub Channel: Delivers up to 1,000 watts RMS to a compatible subwoofer load.
• Bridgeable Main Channels: Main channels can run as 250 watts RMS x 2 at 4 ohms.
• Variable Crossovers: Helps match speaker and subwoofer output ranges for a cleaner setup.
• Selectable Signal Turn-On: Supports remote-wire, DC-offset, or audio-sensing activation methods.
• Included Bass Knob: Lets the driver adjust subwoofer-channel level from the listening position.

Design & Installation

The PRX1500.5V2 uses an extruded aluminum heatsink, single-sided terminal layout, and a removable LED-accented acrylic top panel. Its controls are top mounted beneath the panel for protected access during tuning. Blue LED top-cover and ground lighting are integrated into the design.

Use the amplifier with a properly fused power installation and verify final speaker impedance before connecting outputs. The main channels are rated for 2-ohm stereo operation or 4-ohm bridged operation, while the subwoofer channel is stable to 1 ohm. Mount it in a secure, ventilated location, use the recommended 0GKIT amplifier kit, and set gain and crossover controls according to the connected speakers, subwoofer, and source signal.
