Hi all, i have a slight problem. Ive just tried fitting my alpine unit to my car and when i connect the iso leads up to the car and connect the rca cables for my sub and front comps, the headunit overloads and causes smoke. I dont know why it is doing this. Ive everything connected up ok, I think. The red and yellow wires are running into the car wiring block, but dont these wires just save the station memory. Please help?
