Soundstream Stealth Series SM4.1000D 1000W MAX 4-Channel Marine Amplifier

A compact 4-channel marine amplifier designed to deliver up to 1000W of maximum power output using advanced Class D full-range technology. Housed in a lightweight chassis with a hybrid aluminum alloy heatsink for efficient cooling, it supports 2-ohm stereo and 4-ohm bridged operation, and includes MOSFET power supply with audiophile-grade transistors for enhanced audio performance. Built-in protection circuits guard against direct short, thermal, and overload conditions. The amplifier features variable 12dB high pass, low pass, and subsonic crossovers, along with both high-level and RCA inputs (200mV–12V) via quick-disconnect wire harnesses, making it adaptable for use in cars, motorcycles, boats, or off-road vehicles.
