I connected it to the fuse block on the driver's side, ran it down the wheelwell, and drilled a small hole under the driver's side step. Both the amp trigger and power wires run in the driver's side step trim perfectly. Even when you open the hood, just 3" of red wire are exposed so you can't tell there's a stereo installed. I ran the 60 amp fuse with 3" of wire from the battery + connect, so if the red wire contacts the frame anywhere, the fuse will blow and hopefully won't leave the engine dead. This setup works great, and I only used 8 feet of power wire. (The less the better) On another notw, don't use the cruise control fuse to trigger the amp, because it's noisy.
