[4jacks]

I mounted the brain under the dash as High as possible... I mounted Siren facing Up in the very front of the hood. I mounted the Antenna as high up as possible too... under dash. I get decent range.

And I tried my best to make sure that the wires in the engine bay weren't touching anything hot... I ran the car for a good bit and checked everything they were touching... I also got Shiny chrome Split loom that is suppose to be heat resistent.
