Stelth is best. I did mine in our shop when I gutted my car and changed the interior so I ran all my wires along with the factory wire harnesses. Looks nice and clean and nothing runnign under the hood and riged into the battery. just used the factory fuse box and for the amp. since I took out the factory antena I use the power sorce from it to run the amp since it turns on and off with the radio.
