When space is short, the 4555A 5-channel Class D amp helps you go big for music, movies and podcasts. This Infinity Reference 4ω car amplifier adds some muscle audio while barely being a blip on the electrical load. It delivers 45 watts to each speaker plus 320 watts to the subwoofer in a 4.1 setup. Switch to 2-ohm output or bridge the front/rear channels for even more zip. Peak loads deliver 1,800 total watts that give a factory or aftermarket system a whole new sound. All of it is housed in a compact design for smaller cars and trucks.
The Infinity Reference series of amplifiers shows that Class D technology isn’t just for subwoofers anymore. Features such as variable high/low-pass filters, adjustable crossovers and bass boost vastly improve the sound quality. Its small size, cool operation and efficient operation are ideal for vehicle applications where you don’t need perfect fidelity. ADAS and HALOsonic inputs are also included to integrate with advanced car audio technology. Get answers to all your questions via phone or email with lifetime tech support from OnlineCarStereo.com.
Speaker-level and low-level inputs allow Reference amps to work with just about any car stereo, aftermarket or factory.
Reference amps can also work with vehicles equipped with HALOsonic system. What the HALOsonic enhancement system does is it helps reduce the external noise for a more enjoyable music experience.
