AJMRTC 12V DC 400W Aluminum HiFi Stereo Power Amplifier, Mini Car Audio Stereo Amplifier, Dual Channel Amp for Vehicle Speaker, Home DIY Sound System

AJMRTC mini HiFi stereo amplifier is a compact power amplifier built for 12V vehicle audio upgrades and small DIY sound projects. The rugged aluminum housing rapidly dissipates heat generated during high-volume playback, preventing overheating and extending service life. It delivers peak 400W dual-channel stereo output, bringing louder, more dynamic sound for car speakers, with satisfying bass depth and clear mid-high vocal details for music, podcasts and navigation audio.

It adopts separate control knobs for master volume, bass and treble. You can freely tune the tone to match different music styles and speaker characteristics. Standard RCA left and right channel input accepts signal from car head units, smartphones, MP3 players and other audio sources. Simple wiring design makes it friendly for car audio modification, boat audio, off-road vehicles and small outdoor speaker systems powered by 12V battery.

Built-in filtering circuit suppresses engine noise and background hum effectively, ensuring cleaner audio output while driving. It features short-circuit, over-current and over-temperature protection to safeguard speakers and the amplifier itself. The small footprint is easy to mount under car seats or in narrow installation spaces. It is a cost-effective upgrade solution for anyone looking to improve factory car stereo sound without bulky large amplifiers.
