Amazon 4-Channel Car Amplifier – Class D Compact Powerhouse This Class D 4-channel car audio amplifier features the Infineon IR4322 automotive-grade chip, supporting stereo and bridgeable modes for flexible system setup. Rated at 200W x 4 @ 4Ω/2Ω and 400W x 2 @ 4Ω in bridge mode as a sub amp, it delivers crystal-clear sound across the full frequency range with ultra-low distortion and minimal heat—perfect for upgrading your factory car audio or building a custom system. Hi-Fi Studio-Grade Sound Quality – High SNR & Low Distortion Bringing Fosi Audio's professional Hi-Fi technology to your car stereo, this amplifier is equipped with JRC NJM4580E/ST TJM4558CDT op-amps. It boasts industry-leading specs: THD+N ≤0.006%, 104dB high SNR, and an ultra-low noise floor of ≤140μV. Far surpassing standard car amplifiers in the same price range, it delivers immersive, lossless sound whether used as a 4 channel car speaker amp or a component amplifier for car audio. Versatile 4-Channel Car Amp – Mono, Sub, or Full-Range Ready: Bridge mode delivers 400W x 2 @ 4Ω for powerful bass (ideal as a mono subwoofer amp). Powers tweeters, mids, full-range speakers, or subwoofers. Ultra-low 0.5W standby power and low-voltage protection (triggers at ≤8.8V) prevent battery drain. 88% High Efficiency Class D with Crossover & Pre-Amp Integration The Class D design achieves outstanding 93% efficiency @4Ω (max >88%), minimizing power loss and heat. It features adjustable HPF/LPF crossover (50Hz-250Hz) and FULL pass mode, with a REM terminal for sync on/off with your head unit and auto-on via high-level input for non-RCA setups. Works seamlessly as a pre amp for car audio or with a dsp amplifier car audio system for precise tuning of tweeters, woofers, and full-range speakers. Compact Universal Fit for 12V Vehicles – Micro Car Amplifier Design With a mini size of 186x101x44.2mm (7.3" x 3.9" x 1.7"), this compact 4 channel amplifier fits easily under car seats or in the trunk. Fully compatible with all 12V DC gasoline vehicles (sedans, SUVs, trucks, vans, Jeeps), it offers plug-and-play DIY installation—no professional skills required. A true micro car amplifier that rivals larger amps like Rockford Fosgate, Kicker, Zapco, and Soundigital models. Automotive-Grade Component Durability – Built to Last Constructed with high-quality automotive-grade components including premium Sumida inductors, this car multichannel amplifier is designed to withstand harsh automotive environments. Resistant to temperature fluctuations, vehicle vibration, and road shock, it delivers long-lasting, reliable performance for daily commutes and long drives—matching the durability of top names like JBL, Kicker, and Rockford Fosgate amplifiers. CNC Aluminum Heatsink & Multi-Protection System Built with a precision CNC-machined aluminum heatsink for effective heat dissipation, this amp maintains stable performance during long hours of use. Integrated full-protection features include overheating, short circuit, over/under voltage, and reverse polarity protection. Intuitive LED indicators (PWR/PRT/CLIP) show real-time operation status for quick troubleshooting—reliable protection like premium brands such as DS18, Deaf Bonce, and Boss 4 channel amps. Note: Regarding power, to ensure sound quality, the gain knob's adjustment steps are lower compared to other products. You can achieve a higher volume by increasing the gain knob's adjustment range or turning up the car's head unit volume.
