Memphis SE3200-1V2 800W 1-Ohm Monoblock Amplifier

The Memphis SE3200-1V2 Street Edge is a single-channel car audio amplifier designed to power a subwoofer system. It delivers rated RMS output at 4-, 2-, and 1-ohm loads, giving installers flexibility when matching compatible subwoofers and wiring configurations. Its mono layout keeps the focus on dedicated low-frequency amplification rather than full-range speaker channels.

This amplifier is suited to listeners building or upgrading a vehicle bass system with a compatible subwoofer load. At 1 ohm, it is rated for 800 watts RMS x 1, while its 4-ohm and 2-ohm ratings support more conservative system configurations. The adjustable controls help tailor subwoofer output to the vehicle, enclosure, source unit, and front-speaker system.

A variable low-pass crossover allows the amplifier to limit upper-frequency content sent to the subwoofer. The low-pass filter adjusts from 32Hz to 200Hz and uses a 12dB-per-octave slope, helping blend bass output with the rest of the audio system. A variable subsonic filter is also provided to reduce ultra-low-frequency content below the desired operating range.

The SE3200-1V2 includes bass-management controls beyond basic gain adjustment. It offers adjustable bass boost, phase shift adjustment, and a remote bass-knob connection for accessible level changes from the listening position. Gain is used to match the amplifier's input sensitivity to the source unit, rather than as a primary volume control.

For system expansion, the amplifier provides RCA input connections and low-level RCA outputs for passing signal to an additional amplifier. Its 1-ohm-stable mono output is intended for properly wired subwoofers with a final impedance of 1 ohm or higher. The recommended 4GKIT wiring kit supports a practical installation path for this amplifier.

Key Features

• 800W RMS at 1 Ohm: Supplies substantial mono power for a compatible subwoofer load.
• Variable Low-Pass Filter: Adjusts from 32Hz to 200Hz for subwoofer integration.
• Subsonic Filter: Helps reduce extremely low frequencies sent to the subwoofer.
• Remote Bass Knob Port: Supports convenient subwoofer-level adjustment from the cabin.
• RCA Pass-Through Outputs: Sends the incoming audio signal to another amplifier.
• Extruded Aluminum Heatsink: Helps dissipate heat during amplifier operation.

Design & Installation

The SE3200-1V2 uses an extruded aluminum heatsink and a compact chassis measuring 7.87 x 8.07 x 2 inches. Its control panel combines RCA input and output connections with gain, bass boost, low-pass, subsonic, phase, and remote-level controls. Power and protection indicators provide basic operating-status feedback.

Install the amplifier in a dry, secure location with adequate airflow around the heatsink, such as a trunk, hatch area, or behind a pickup-truck seat. Use a compatible subwoofer configuration that presents no less than a 1-ohm load, and use the recommended 4GKIT wiring kit for power delivery. Connect RCA signal cables from a source unit, set gain correctly, and use the crossover and subsonic controls to suit the subwoofer enclosure and system response.
