Memphis SRX1200.1V 1200W Mono Subwoofer Amplifier

The Memphis SRX1200.1V is a mono car amplifier designed to power a subwoofer system with substantial continuous output. It delivers 550 watts RMS at 4 ohms, 950 watts RMS at 2 ohms, and 1,200 watts RMS at 1 ohm. This makes it a practical choice for systems built around one or more subwoofers wired to a compatible final impedance.

Its single-channel design concentrates available power on low-frequency reproduction rather than full-range speakers. A variable low-pass crossover lets the amplifier focus on bass frequencies, while the variable subsonic filter provides additional control over the lowest frequencies. These adjustments help tailor the amplifier to the subwoofers, enclosure, and vehicle acoustics in the system.

The SRX1200.1V includes selectable bass boost settings at 45 Hz for users who want to adjust low-end emphasis. A wired remote level control is also included, allowing output level adjustment from the front of the vehicle. The gain control should be set carefully during installation to match the signal source and connected subwoofer system.

Memphis uses a textured aluminum heatsink chassis to support heat dissipation and provide a durable mounting surface. Dual LED accent strips add illumination when the amplifier is powered. The amplifier also incorporates protection circuitry for conditions including short circuit, overheating, and abnormal battery voltage.

This amplifier can be integrated with aftermarket receivers through RCA inputs or with compatible factory audio systems through its speaker-level input harness. It is intended for a dedicated subwoofer stage in an entry- to mid-level vehicle audio upgrade. Use appropriately rated wiring, a correctly fused power connection, and subwoofers that present a supported impedance load.

Key Features

• 1,200W RMS at 1 Ohm: Provides high continuous mono output for a compatible subwoofer load.
• Variable Low-Pass Filter: Helps keep high frequencies out of the subwoofer channel.
• Variable Subsonic Filter: Lets you limit ultra-low frequencies below the selected cutoff.
• Selectable Bass Boost: Offers 0, 6, or 12 dB adjustment at 45 Hz.
• Wired Remote Level Control: Allows convenient subwoofer-level adjustment from the listening position.
• Textured Aluminum Heatsink: Supports heat dissipation in a compact amplifier chassis.

Design & Installation

The SRX1200.1V has a black textured aluminum heatsink and ultra-bright LED accent lighting. Its compact chassis measures 12.5 inches long, 7.87 inches wide, and 2.16 inches high. Internal protection circuitry and three 40A ATO fuses are incorporated into the amplifier.

Mount the amplifier in a secure, ventilated location and use a 4-gauge amplifier wiring kit as recommended by Memphis. RCA inputs support aftermarket source units, while the supplied speaker-level harness can be used with compatible factory-radio speaker outputs. Match the connected subwoofer wiring to the amplifier's supported 1-ohm minimum load and set crossover, subsonic, gain, and bass-boost controls during system tuning.
