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.

Frequently asked questions
Do I still need to run a wire to the battery?
No. The EAZ-C02 taps into your factory power seat connector, which already carries a 12V power supply. No firewall routing and no battery terminal connection required.
What type of subwoofer is this compatible with?
The EAZ-C02 is compatible with active (powered) subwoofers and amplifiers with high-level inputs. Maximum continuous power supported is 280W at 14V.
My Toyota model says driver's side only - what does that mean?
On those models, the power seat connector on the driver's side is compatible with this harness but the passenger side is not. The harness will work for powering a subwoofer placed under or near the driver's seat.
Is this fully reversible?
Yes. The EAZ-C02 uses OEM-grade plug-and-play connectors. It can be removed at any time with no permanent changes to your vehicle.
Does this ship to Canada or internationally?
