am getting my alarm installed tommorrow at Circuit City. I mounted the 2 sirens (the 850VX siren & a DEI Piezo) myslef since I did not want them to be visible when looking at the engine bay. I am wanting to run the wires back to where the brain will be. Do I have to run all 4 wires back to the brain or can I splice the 2 sirens together (black with black / red&black with red&black) and run 2 wires back to the brain loaction? The 2 sirens are located next to each other and which is why I ask.

I do plan to add another Piezo or 2 (inside the car) in the future.

Thanks for any help on this!

PS <> Each siren has 2 wires: 1) red 2) red/black
