💡 Why do aftermarket electronic sirens fail under high voltage loads?
- Inconsistent voltage drops frequently damage internal driver transistors
- Poor cable gauge choices create resistance that starves the coil assembly
- Proper wire sizing eliminates signal noise and keeps the circuit clean
- Adding a fuse block protects sensitive components from sudden power spikes
