i searched, but couldn't find the answer i needed.

i have a 99 civic ex and the factory horn is one wire. i need to send power to both horns. will this wire and the factory relay we able to handle these horns or should i use another relay and my own fused power source?

thanks guys... i'm doing the install tomorrow after noon, all help is appreciated.

 

i dont think so, because the guy that install my second siren install other relay for the horn.

 

please dont put an aftermarket horn in your car
