Effective noise suppression - Eliminates noise and unwanted hum without changing the original car audio tone. Optimized performance - Supports high current operation, low harmonic distortion, and safer operation for clearer sound. Improved signal quality - Improves the audio signal, reduces noise, and preserves higher fidelity with a robust copper cable to minimize motor interference. Intelligent design - Maintains sound quality by eliminating the ground loop with a single noise-detection circuit. Use scenarios - In-car audio installations with aftermarket amplifiers to suppress engine and alternator noise. - Vehicles with long wiring runs or multiple speakers where clean signal is critical. - Systems using copper wiring to minimize motor and electrical interference for better sound. Key attributes - Function: noise suppression, ground loop elimination, signal integrity - Compatibility: designed for car audio systems (factory and aftermarket) - Material: copper cable - Performance: high current capability, low harmonic distortion
