I purchased a Clifford Matrix 12.5X off the web and want to install it into a 2004 Dodge Ram Quad Cab SLT. Does anyone know of any added parts I would need to do this install? Diode's, relays, etc? I would also like to add an Piezo Siren in the cabin. told no one could stand to be in the truck if this was going off. Where can I purchase one of these and how do I hook it up? I was told it is like 190DbA but the web searches I have done I can only find 105DbA or lower.
