I SOLD MY CAR I DISCONNECT THE BACK OF THE RAIDO NOW I DO NOT HAVE THE WIRES FOR PWER, SPEARKS,GROUND,ECT.

Power turn on for the amp. might also have one that is for antenna.

Bad Idea. Don't do it.

It depends on how far from the battery is mounted from the amp. I would use 4 gauge for both power and ground. The grounding point should be about 18 inches from the amp. You could always use the 4 gauge to a Fused Distribution block and a short run(18" or less)of 8 gauge to the amp.

buy a car raido installation kit for your car not more than $20 then it will tell you what wire goes where power ,ground , memorey , ect . do not cut ant thing

try making sure both the red and yellow wires are getting power. Both wires need to have power going to them in order for the radio to work.

You have a SHORT CiRCUiT problem and only ur Auto Electrician can pinpoint where it is! The wire going to ur DOME light might have splintered and touch the body ground! The STEREO might have problem in its amplifier and power line thats why it kept blowing ur 10amp FUSE! Hope that might help u out! Taah!

You need three wires to power on a radio
yellow 12v constant
red 12v switch (turns off/on with key)
black ground

Verify these three and the fuse on the back of the radio as well

Hi what ever location you find under 18" from the amp you must clean it down to bare metal and bolt the wire tight also rca wires are run down opposite site of vehicle then the power wires. If you still have a humming sound check the ground on the radio make sure your not getting it primarily from the antenna. If its still there you can try a noise suppressor sold at bestbuy or radio shack ect.

you connect the wires stupid!!!

You could have melted some wire's or blown the fuse in the actual radio it'self if it is a newer style radio i suggest taking the face plate off pop the side tabs slide the radio forward disconnect the harness and antenna booster check the fuse, should be on the back left or right corner also inspect the wiring ground wires ignition power wire ect. Also check the actual car fuses in you're car and when checking wiring be alert and use a electrical light tester or volt meter for power and ground and ect also cap or temporarliy tape all loose wires if you did not use a adapting harness.
