Memphis Audio SE1000.1V2 Street Edge Monoblock Amplifier

The Memphis Audio SE1000.1V2 Street Edge is a single-channel car amplifier designed to power a subwoofer system. It delivers 160 watts RMS at 4 ohms or 250 watts RMS at 2 ohms. This makes it a practical choice for adding dedicated low-frequency amplification to a vehicle audio system.

This amplifier is intended for shoppers building a straightforward bass upgrade with a compatible 2-ohm or 4-ohm subwoofer load. Its mono layout concentrates its output on one bass channel rather than powering full-range speakers. The adjustable low-pass crossover helps keep higher-frequency content out of the subwoofer channel.

The SE1000.1V2 uses a variable crossover section with a low-pass filter adjustable from 40 Hz to 400 Hz. The low-pass filter uses a 12 dB-per-octave slope, allowing the subwoofer channel to be blended with the vehicle's main speakers. A subsonic filter is also included for additional low-frequency system tuning.

For everyday adjustment, the amplifier includes a remote bass knob for mono-amplifier use. Input sensitivity is adjustable across a 0.2 to 6 volt range to accommodate a variety of source-unit or signal-processor outputs. RCA inputs connect the amplifier to the audio signal, while a low-level output can pass signal to an additional amplifier.

An extruded aluminum heatsink forms the amplifier's exterior and supports heat dissipation during operation. The chassis measures 9.76 by 8.07 by 2 inches, helping it fit in many trunk, hatch, or behind-seat mounting locations with appropriate ventilation. It is designed as a focused subwoofer-amplifier addition for a system that needs controlled bass power.

Key Features

• Mono Subwoofer Channel: Dedicated single-channel amplification for a compatible subwoofer load.
• 250W RMS at 2 Ohms: Provides its highest rated RMS output at 2 ohms.
• Variable Low-Pass Filter: Adjusts crossover frequency from 40 Hz to 400 Hz.
• 12 dB/Octave Crossover: Helps tailor the subwoofer’s upper-frequency roll-off.
• Remote Bass Knob: Provides convenient bass-level adjustment from the driver area.
• Aluminum Heatsink: Extruded housing supports thermal management and durability.

Design & Installation

The SE1000.1V2 uses an extruded aluminum heatsink chassis and includes controls for gain, bass boost, low-pass filtering, subsonic filtering, and phase shift. RCA input jacks accept a low-level audio signal, and a low-level output is provided for feeding an additional amplifier. The amplifier includes +12V, ground, remote-turn-on, and speaker-output connections.

Mount the amplifier securely in a dry location with adequate airflow, such as a trunk, hatch area, or behind a pickup-truck seat; avoid mounting it with the heatsink fins facing downward. Memphis specifies a 35A fuse and recommends its 8GKIT amplifier installation kit; the manual states that the +12V and ground leads should be 10 AWG or larger. Verify final speaker impedance before connection, as the manufacturer does not rate this model for 1-ohm RMS operation.
