For those looking to install a basic subwoofer, you are going to need a solid and reliable amplifier. The Soundstream Di475.1 is just that, a simple and reliable amplifier. Wired at 4 ohms, the amplifier will produce a stable 350 watts to a single channel. When wired down to 2 ohms, the amplifier is rated at 475 watts. That is plenty of power for a basic subwoofer that can fill in that low bass without overbearing the rest of the speakers. The Soundstream amp is made using a Mil-Spec fiberglass circuit board and powered by a PWM MOSFET power supply. If you don't have an aftermarket stereo, or just prefer to use speaker level inputs for your amplifier, this amplifier will be compatible and includes the speaker-level input harness. The inputs and screw terminals are nickel plated for optimal signal transfer and the heatsink keeps the amp running cool. For those just getting into the world of car audio, this is a fantastic amp that will power your basic subwoofers. The Soundstream Di475.1 is named the Extreme Bass Machine for a reason!
