The Directed 4 Channel Class A/B Amplifier 250/4 is a versatile and powerful car audio component with a sleek silver design. This amplifier, with RMS power of 50W, can configure up to 4 channels for a variety of audio setups. Made in China by the trusted brand Directed, this amplifier is a reliable choice for enhancing your vehicle's audio system with a bridgeable design for customizable power output. I bought a truck the amp was fully functional and hooked up but I don't use amps in my trucks so I pulled it it's 100% working. Thanks for looking
