Audio Impedance, Dyno & Wattage Multimeter – Car Audio Testing Tool

Audio Impedance, Dyno & Wattage Multimeter – Car Audio Testing Tool

This Listing Includes:

• (1) Audio Multimeter
• (1) Protective silicone boot
• (1) Harness

This Audio Multimeter & Handheld Dyno is designed for car audio enthusiasts and installers to measure true amplifier power, speaker impedance, AC/DC voltage and current, apparent power, frequency, and more. It allows tuning of subwoofer enclosures for maximum power transfer, verifies impedance across frequencies, and measures phase differences for reactive loads. The included protective boot and harness ensure safe and reliable use.

Key Features & Benefits:

• True Amplifier Power Measurement: Accurately measure wattage into any resistive or reactive load
• DC & AC Voltage/Current: Test voltage drops, AC/DC volts and amps, and apparent power
• Speaker Impedance Testing: Measure impedance from 20Hz–1kHz for boxes and subs
• Phase & Power Factor: Check phase difference to optimize system performance
• Subwoofer Tuning: Find enclosure tuning frequency and maximize power transfer
• Frequency Analysis: Measure audio signals from 10–20,000 Hz
• Durable Design: Includes silicone protective boot and field-replaceable harness
