Monoblock 1000 Watt 2-Ohm Micro Compact Car Audio Amplifier Soundstream ST11000D

This listing includes:

• (1) Soundstream ST1.1000D Amplifier


• (1) Dash Mount Gain Control Module

The Soundstream Stealth ST1.1000D is a high-efficiency Class D monoblock amplifier that delivers impressive power in a micro-sized chassis. Measuring just 3" Ã 1.5" Ã 7.75", this compact amplifier packs 350W RMS @ 4 Ohms and 500W RMS @ 2 Ohms, making it ideal for cars, motorcycles, boats, or off-road vehicles.

Once considered "dirty power," modern Class D technology now provides stable, clean, and high-performance output, rivaling traditional full-range amplifiers. With minimal power requirements, ultra-compact design, and easy installation, this amplifier is perfect for any full-range audio setup.

Automatic Hi-Level Signal Sensing Turn-On allows integration with factory radios without needing a remote wire - the amplifier powers on/off automatically when a signal is detected.
