What could be the issue? Installed new factory deck and amp but still don't have sound in my 2005 G35 coupe. Please help

 

I would assume u didnt install it correctly.

 

What could I have done wrong? It's all unplug and plug back in?

 

Hmm. Pretty difficult to troubleshoot issues like this. Whats the history? Old one was working and just stopped?

 

Yea. Everything comes on. Just no sound

 

Get a cheap little speaker and hook it up directly to one of the speaker wires behind the head unit. See if u get any sound like that.

 

OK I'll try that tomorrow when I have more time. U happen to know which wire's are for the speakers.

 

Lets use the front left speaker. White+ Black-

 

You need to get a a multimeter and start checking connections.

 

^^^
If you touch the speaker wires or the speaker itself with a AA or AAA 1.5v battery you should hear a sound from the speaker if the speaker is good

Touched a AAA battery to the speaker wire's and didn't make any sound. So I checked for power and there is no.power to the speakers in the back.

 

Touch the + and - of the AAA battery directly to the rear speakers on at a time. If the speakers are good you'll hear a click from each speaker.
Then trace the speaker connections thru the wiring harness's back to the amp
Also you could try a test speaker connected to the speaker output of the amp to confirm sound output from the amp

Use a tone generator and probe to find the open in the rear speaker wiring.
You can find those in the electrical dept of Home Depot

Out of box failure perhaps?
Does the old one work?

 

No the old 1 didn't work either.

 

Speakers made noise when I touched wires to a better so they are good.
