The LF Audio WTH is a wireless temperature monitoring hub built to keep an eye on the heat inside extreme car audio systems. It supports up to eight sensors in total, four infrared and four thermocouple probes, so you can track subs, amps, batteries and more in real time.

Industrial differential signaling filters out the electrical noise thrown off by high-amperage cabling and digital amplifiers, keeping readings stable even next to power distribution blocks and high-output alternators. Live data streams to the AuralSync app, WVC Knob, WDD or WDD-LITE, and you can set up to four custom temperature zones per component to flag when things get close to critical.
