The Beat-Sonic EAZ-C02 is a plug-and-play power harness that lets you power a new active subwoofer directly from your Toyota or Lexus power seat connector - no firewall routing, no running wire to the battery terminal, and no permanent modifications to your vehicle. Clean, simple, and fully reversible.
Professional local installation available in La Mirada, Southern California. Contact us at info@beatsonicusa.com to book.
Why this harness makes adding a subwoofer so much easier
Traditionally, powering an aftermarket subwoofer meant routing a power cable from the battery through the firewall - a time-consuming process that risks damage to factory wiring and requires drilling or finding existing grommets. The EAZ-C02 eliminates all of that. It taps into the existing power seat connector under your seat, which already carries a clean 12V power supply, and provides a fused, plug-and-play power connection for your active subwoofer or amplifier right where you need it.
