The Wire Meter Wireless Voltage Monitor
Monitor your system voltage in real time without running a single wire.
The Wire Meter is a compact wireless voltmeter designed for car audio setups, battery monitoring, and clean installs. It lets you keep track of your voltage from anywhere in your vehicle with a dedicated display — no apps, no delays, no guesswork.
Built for reliability and simplicity, the system uses a transmitter connected to your power source and a separate display unit that receives the signal instantly.
