2 Amplifiers 1600 watt Monoblock & 600 Watt Sony Amplifier

Both amps work perfectly. The VM Audio EXA1600.1 1600W 1 Channel Amp monoblock is for the subwoofer(s) . Amplifier 1600 watts max x 1 channel at 2 Ohm. Its extremely low noise distortion means this amplifier runs quietly and efficiently, and it offers a dedicated soft turn on circuit. The Fidelity Class A/B Circuitry delivers precise half signal transitions with low heat generation. Signals are reproduced separately and joined together to complete the full signal. Measuring 11.57"L x 9.65" W x 2.17" H, Nickel Plated Rust Resisting Post Connectors Digital Over Voltage Protection System Sony XM-GTX6040 is a 600W maximum, 4/3-channel MOSFET amplifier is for the mids and highs. Channel Configuration: 4/3 channel Amplifier Class: A/B Power Supply: MOSFET Frequency Response: 5-50kHz Total Harmonic Distortion (THD) at 1kHz: 0.05% Signal-to-Noise Ratio: 100dB Filters: High-Pass Filter: Variable, 80Hz, -12dB/oct Low-Pass Filter: Variable, 80Hz, -18dB/oct Features Input: Speaker-level (high-level) and preamp-level (gold-plated RCA) inputs Operation: 4/3 channel operation for flexibility in system setup Heat Dissipation: Heavy-duty aluminum alloy heatsink Indicators: LED power (green) and protect (red) indicators Protection: Soft Start Turn-on. Both amplifiers are missing a couple screws that hold the cables in place.
