Review on 🚨 Mophorn 200W Car Warning Alarm Kit with MIC System - Vehicle 7 Sound Loud Warning Alarm, Emergency Fire Siren, PA Speaker by Ethan Carpenter

Pros: These are the right universal tones and the horn is the right horn (no Mickey Mouse crap) and they are crisp. I have it for the siren function and it works fine. The Bad: The schematic isn't that good. How to install it (USA). Red - plus 12V (battery), black - minus 12V (ground), white - switch #1, plus 12V to lamp #1, yellow - switch #2, plus 12V to lamp #2. Yellow on relay, indicator light, so In order not to "overstrain" the power of the switch amplifier, green goes to the speaker. Note: Before turning on the power, isolate all connections and connections to the speaker. Ground the live speaker wire to damage the device. Deformity: My mic arrived damaged and rattled right out of the box causing the mic/amp to not work. I've seen the same problem with devices that cost twice as much. The rest of the amplification system works well so I think a new mic will fix that. Anyway I bought it for a siren (no speaker) and it works really well so for the money you can't beat it.
