I have a 98 Civic that has an aftermarket HU and 4 kicker speakers, 2 in front and 2 in rear. Had a local shop install the head unit and I did the speakers. All of a sudden my driver side rear speaker stopped working. Took that speaker and hooked it up to passenger side rear wires and sound came out. I connected a working speaker to the driver side rear wires and there was no sound. Checked behind the HU and all connections seemed to be good. Took a multimeter to the rear driver side wires and got no reading. Then I took normal speaker wires and connected them to the driver side rear speaker and the + and - wires behind the HU and it worked, so I'm thinking that I have a short somewhere in either the + or - speaker wires that snake through the car. How can I determine where this short is coming from? Thank for any help.

 

Just run new wires.

 

Well it is just the driver side rear that isn't working. What pieces of my car do I need to take apart to hide the new wires?

 

What Civic trim?

 

Not sure what you mean by that but its a 98 civic dx

 

Hatchback, coupe, sedan?

 

sedan

 

Here is how the left rear speaker wires are routed:

Dashboard harness
radio C515 --> C503

Floor wire harness
C503 --> C562

Rear wire harness
C562 --> C603 left rear speaker

If you continuity test the left speaker wires (+ and -) contained in each wire harness (Dashboard, Floor, Rear), you may identify which wire section has the break. Then you only need to run a new wire for that section of wire.

 

Where do I place the multimeter probes to test continuity, would it be black the negative terminal and red to positive terminal in harness? What should reading be at? What pieces do I need to remove to access floor and rear terminals?
