Installed the siren yesterday. It works as well as can be expected and a great value for the price. The small size fits well into the engine compartment of my 2005 Kia Sedona mini van. It states that it is (2) tone, but all it does is sound low or loud. Thats ok. I cut and the blackwire and got no difference from having the wire not cut. Again it works fine. I received the item in record time. There are no instructions, but installation is very simple, only 2wire connection. I highly recommend this item and i am very satisfied with Sonic Electronics. Will diffenately buy from them again. Emmet Hunt Loganville, Ga.
