I have the Rockford Upgrade in my 03 Frontier. I am planning on replacing the stock sub with an amp and larger sub behind the back seats. My question is, does anyone know what color the amp turn-on lead from the factory head unit is? I assume that there is one to turn on the Rockford factory amp. Thanks

yea, I've been looking for information on this system for months. It's like a big conspiracy. Maybe some license infringement as well?, though. Even so, I have not been able to even come up with a layout or good specifications of the system. Crutchfield did say that there was a turn-on lead but I would have to buy one of their amps to find out. Also, I know that the sub is a dual voice coil 2ohm wired parallel into the rear channel. So I am not sure how many watts actually power the sub. Guessing 40 rms.
