Car Stereo Has Power But No Sound

Hey Guys,

Okay so the problem which I'm unable to sort out since last 3 weeks is about having no sound from my speakers while the head unit is working properly. And the sound comes back as soon I short the speaker wire with the bare metal. and i need to do this to right-rear speaker only, means it won't work if i do it with the left-rear speaker.

My Car is Honda Fit, I checked all the wiring twice, in fact thrice, ground is good, there is no factory amplifier and all the goods (head-unit & speakers) are after market. the fuses are good and head-unit is getting proper power, speaker wires are fine. yet every time I leave the car for a while, after coming back, i need to short the wire to get sound.

Would Highly appreciate if someone can put me on the right track to the solution.

Thanks

What is the total resistance of the connected load? The head unit more than likely needs replacement but I would be concerned about how the speakers are connected to prevent a new head unit failure.
 
Thank you Pery & twilliar for jumping in. While trying to figure out the resistance, I observed weird type of wiring for rear speakers. Like the same head-unit was working fine with front two speakers but the problem started as soon the audio guy installed the rear speakers. The guy made a messy back wiring. the head unit is connected to factory stock wiring harness but at the rear, he stripped the factory wiring for speakers and made T-Joints to pull the wires for speakers. Can this type of wiring method cause the issue?
While I still couldn't get the resistance though, cause this strange wiring mess caused me waste a complete hour to understand what's going on.

It really sounds like running a pair of wires to the back will be the easiest/best solution for you, but...

Most installers keep a known good speaker around as a test speaker. Just a small one with a foot or two of wire soldered on, so they can quickly connect directly to the output of an amp or head unit to verify there is good output.

If you have something to use as a test speaker, connect it directly to the head unit's rear speaker wires to bypass everything else and verify the head unit works properly.
