Item Details Condition USED Brand Memphis Audio Weight 5.1000 UPC 702588006060 Highlights 4-channel full-range amplifier rated at 125W RMS x 4 @ 4Ω, 200W RMS x 4 @ 2Ω, or 400W RMS x 2 bridged @ 4Ω, giving you flexible power options for front/rear speakers, components, or a combination of speakers and small subs.Built on an extruded aluminum heatsink chassis measuring approximately 7.5" x 2" x 8.7", designed to help manage heat while keeping the amplifier compact enough for under-seat, trunk, or side-panel installations.Features 12dB/octave Butterworth crossovers with variable high-pass and low-pass filters (HPF: 50–250Hz, LPF: 50–250Hz), allowing you to tailor the frequency range going to each channel for component sets, coaxials, or bridged midbass/sub setups.Includes 3-position EQ boost (0, +6, +12dB) so you can add controlled emphasis where needed, along with a frequency response of 10Hz–25kHz, THD under 1%, and a signal-to-noise ratio greater than 80dB for clean, wideband audio performance.Offers a broad input sensitivity range of 400mV–7.5V (low level) and 3V–20V (high level), making integration straightforward with aftermarket head units and many factory systems that provide either preamp or speaker-level outputs.
