When I lived in BC going to WMU for aviation woop woop
I got a viper alarm and a set of ba 60's from them...
They are overpriced by 30% in my opinion, There work was of good but once again the price is ouch....
I would suggest seeing if you can do it yourself..at the time I didn't know enuff about car alarms to install the viper and as for the ba60's I didn't have the time to get it all done with classes and flight.
They do good work, in a timely fashion but you pay for it a pretty penny
shop around and see if you can fined someone local to help teach you how to do it.
