This alarm is a awesome alarm i seen the price sonic is offering for and im so mad, i paid $340 at a local store for this alarm, just shows you how much local economy is hurting, but yes i would recommend this alarm to anyone, great range great features..

good operating range with neat (small) transmitter, and so far its still working well with little - no false alarms.
cons. Too many add on relays needed in installation

I installed this alarm on an Acura TL. Everything works flawlessly. I couldn't have received this car alarm at a better price. I would recommend this alarm to anyone who is looking for a great deal and versatility. Thanks Sonic Electronix!!!

The Astra 4000 is a good car alarm and the price is good also. The remote beeps when someone hits your car. I recommend this car alarm two anyone.

I am a professional back yard remote starter installer. This system has the features and function of a much higher priced system. This, by far, is the best bang from the buck. I've dealt with Compustar, Ultra Starters, and now Scytek. If you want a great system and don't want to spend a bunch of money, this is your kit.

I am an installer and i have installed this alarm on many cars and have found out it is a fairly easy alarm to install for a basic or even a advanced installer. Never have had one go bad or mess up. I would highly recomened this item to anyone looking to add remote start.
