Almost every radio comes with a remote wire (on most trucks/cars its a skinny blue wire) so just attach it, your rca's, the power wire and the speakers to the amp and you'll be set (just an FYI though you'll more than likely have to buy a kit for the RCA's). Oh and one more big thing if your doing it yourself and you probably already know this but if you are doing it yourself I STRONGLY suggest disconnecting your battery prior to taking the stock radio appart cause if you touch a live wire anywhere near your switches for your A/C it could fry the wiring and you'll be left without A/C untill you pay to fix it and thats a little pricey (learned that one after my sisters boyfriend put a sterio in her truck, $350+ just to replace the wiring for that a/c ****!). Also check before you put it all back together that there are no lose or bare wires too cause that will come back and bite you.
