The PowerBass ULX-485 is a budget-friendly 4-channel car audio amplifier designed to boost your sound system’s performance. It delivers up to 8000 W peak power (typically rated around 85 W RMS per channel) to drive front, rear and even small subwoofers with more authority than a head unit alone. Built on a Class AB topology, it aims to provide clear sound with low distortion, and features like RCA and speaker-level inputs, bass boost and crossover controls give you some flexibility in tuning your system. A built-in cooling fan and solid construction help it handle daily use at high volumes, making it a good entry-level amp for upgrading factory audio.
