I’m not a mechanic by any means, so any help will be accepted and I’ll be grateful.. I bought my 2005 scion TC (used) with an after market radio installed and with no sound. The radio is fully functional… Behind the radio when i pulled it out i found one harness/bracket of wires connected and a bunch of loose wires.
I figured maybe this was ok and decided that the speakers were blown or no longer in the car, so I ordered speakers and amp and me and a friend installed them (mainly him). the amp has power and it is all ran/connected/wired correctly to my knowledge, But still no sound. So if anyone could help I would be very grateful. And I’ve checked all fuses connected directly to amp and radio (HU) itself but not the ones in the cars fuse box???
I’ve read and asked around and most answers are i need to fix the radio harness/bracket or find a way to connect the rest of the “Loose wires”. I can figure out details of radio(HU)/amp/speakers when and if needed.
Have no idea what your aftermarket radio wiring is but I can provide you with the stock wires.
Most radios need power on the two biggest wires and ground on the black wire, then hook up one speaker on two of the little wires, if you get no noise.. radio is no good typically.
One fuse in the engine compartment (RAD 1) 20 amp fuse BLU wire
One fuse in the instrument panel location (ACC) 7.5 amp fuse GRY Wire
