For my Nissian titan 2005 truck -When plugging in my speaker harness to my factory radio it starts making a buzzing noise coming from the speakers does anyone know why?

Buzzing sound through speakers with vehicle running or not running?

you need to check the ground on all speakers. also if you are using any type of RCA cables those may be loose.

If the radio is turning on but no sound.

!. The wires behind the radio for the speakers are lose
2. If they are on a wire harness make sure the wire harness is plugged in right. " you might have to unplug and re-plug it back in
3. The best way to check you speakers is use a 9v battery. Un Plug them from behind the radio touch the positive side of the battery. You should get a little noise.
4. If you have a electrical meter you can check each of the wires coming out of the radio make sure you have it on the DC volts to check everything. " making sure you have power coming out of each speaker wire from the radio." Hope this helps out

It could be coming from the CD/radio unit. If it is aftermarket, there could be a loose wire behind the unit.

Are your speakers factory? Sometimes the wires start corroding from moistures or from not being covered well. If you can or know someone who can, you may try checking the wires to the speakers/radio. If they are corroding, they may be shorting out.

I a '83 camry, there are 2 seperate plugs that go into a factory radio.
One for Power/and front speakers, and the other for rear speakers.

Sounds as if you are missing part of the harness for the rear speakers (or it is shoved in the back of the dash unused by the previous install). If there is not an un-cut plug in the dash - your only course of action would be to run your own set of speaker wire to the rear.

See this picture... these are the plugs that should go into your factory radio....


Metra kit 71-1938 will go from your factory wiring directly into your factory radio.


Thanks for using FixYa - a FixYa rating is appreciated for my effort in answering this Freebie question.

Red - Power
Yellow - primary power must be joined to the red
blue - Remote
Black - ground or negative
To find your speaker wires check the color of the cord behind each speaker than match it with the same color in the dash.
or the easy way is to use a normal 1.5v penlight battery and try each speaker cord behind the dash and listen to which speaker give off a crackling noise so you can get the balance on the cd player right.
If u trying to find power in the car and don't have a tester than get a 12v light or bulb join the negative to the body and push the positive wire into each one of the holes in the factory plug in the dash one at a time until the light comes on. That is your positive the rest is easy. (DIY guru)

Can purchased an adapter kit at Best Buy or Circuit City that is color cordinated with the factory wires for about 12.00. This will go right into the factory plug.

Immobilizer Bypass Module: Required: Yes Type: Passlock 2 Part #: 457G, 555L, or 555T
Notes: The Passlock 2 wire colors are yellow, orange/black, and red/white (not used).

They still follow the GM standard:

LF+ tan
LF- gray
RF+ light green
RF- dark green

LR+ brown
LR- yellow
RR+ dark blue
RR- light blue

Note that if you're looking for them behind the radio, some of the same colors may be used on other wires. The speaker wires should be placed side-by-side for each speaker.

Also, if you're replacing the factory radio, I highly recommend buying a wire harness adapter instead of cutting off the factory plug.
