Review: Great Amplifier!!!! - Easy installation and very compact. Great siren controller with two aux switches to control lights. As others have said, it would certainly make life easier if the switches and buttons were backlit for nighttime responses. Otherwise, I am extremely satisfied with this controller with built in 100 watt amplifier. Paired with the Whelen SA315P speaker this set up REALLY moves traffic when responding to calls.
Review: Five Stars - Love this siren it get five stars very compact and really loud

## Questions & Answers

**Q: Was the unit supposed to come with a position connector? According to the diagram, there is supposed to be one but mine didn't have it. Does it matter**
A: hey do you have the whelen diagram or the one that was in the box if you have the one in the box don't use it use this one http://www.whelen.com/install/143/14302.pdf

**Q: is it waterproof**
A: No we suggest this not be exposed to water.

**Q: How many lights can you hook the aux switches up too**
A: Each switch has a capacity of 20 amps, as long as that is not exceeded per switch there isn't a hard limit on how many lights can be linked to a switch.

**Q: Looking at the wiring diagram, it looks like it hooks into the factory horn. Can you toggle between the factory horn & Whelen horn somehow?**
A: You could wire ina switch in line of the gamma side to where it would break the circuit for it and you just use the regular horn
