I liked the FRD24 myself. the only wires you cut are within the FRD24 and not one oem wire needs cut. it gives you RCA outs, you run them to the amp,,, then you run wires from the amp speakers out into the FDR24 which then feed all the speakers in the truck. I did my in my house and all I had to do is hook up the amp, unplug the Head Unit connectors and plug in the FRD24 and I was up and running... sync, steering wheel controls and everything works just like it did from factory!
