Go a different route in that case! I had the Alpine perfect fit kit, which is similar to the Scosche. I also had to use the FARK in conjunction, which works great. I will try something new with my future project. Instead of using the FARK and intercepting the audio signal before it leaves the amp I will intercept it AFTER it leaves the amp. Audiocontrol makes it's units capable of accepting amplified signals from a stock HU and sum up the channels. I will keep the stock HU and use the Audiocontrol LC7i, look it up, it allows you to add RCA outputs, and gives you a true subwoofer output, and much more.
