[QUOTE="keep_hope_alive, post: 8228047, member: 576029"] possible the antenna jack/cable is busted, or there is a short in the antenna wire/jack/plug. if just one strand of the shield touches the center conductor - reception drops to near zero. make sure the antenna cable has the center pin in-tact. make sure nothing is inside the antenna jack. did you need an antenna adapter to change from small to large? neaten your wires. group wires logically and zip tie them. I use around two dozen zip ties behind a head unit. I group wires, secure wires, and make sure to account for bending. I avoid wires being pinched or smashed. I don't use electrical tape because it gets loose over time with heat/cold. excess wire is bundled and stashed in the dash, above or below the radio. sometimes I remove more trim panels so I can train wires as i'm inserting the head unit. it's time consuming but you'll be happy in the long run. in the future, don't move electronics around when they are on. pull associated fuses before working on the radio (or disconnect battery negative). usually, the blue wire on the back of the aftermarket radio is power antenna lead. it can power an antenna directly or through a relay. or the antenna amplifier can be ignition powered so it is on when the car is on.
