i just installed the HU, and power is working fine, but no sound!!!!
i used wire kit, and i did match the colors.
another question is.. i have boss one.. with the controller on the steering wheel,
and there were total 4 cables connected to the stock HU.
does anybody know what the bottom 2 connections for?
and any idea what sound is not working?!?!
please help!!!
thanks in advance!

 

Turn up the Volume.

 

i tried that.. any more thought?

 

You have power, Put in a CD and tried the Volume with no Luck?

You matched up all of the wires and Insulated them well when you hooked up the harness right?

You plugged in the Factory Antanae Lead?

 

yes i did...
i tried..
1. just the audio plug
2. audio plug with sub output
3. audio plug with antana
4. everything..
but same thing.. any more thought?
thanks!

 

Any Amps?

Can you show some pictures of how it is all wired up?

 

ah... it's too hard to draw the pics..

i connect same wire colors to same colors.
and connect the stock plug.
but some how.. there is no sound........
but there is power..... any guesses?

 

Power AMP... the blue wire, connect it to 12v.

Irt happened to me, the radio powered up but no sound, it was the power amp signal.

hope it helps

OE

 

well if your amp is geting power but no sound, it seams that your amp remote wire (usually a light blue) is not hooked up right or is grounding. this wire is conected to the back of the HU and tells the amp to turn on. hopefully that helps. also make sure none of your connections is touching any metal.

 

OK guys, i have the same problem with no sound .
Here is the setup: I have a 05 Touring Z with bose and navi..
What i did is got an aftermarket headunit and an amp.
So, i took out the bose headunit and put mine instead. I wired everything with the MEtra wiring kit (http://www.crutchfield.com/S-YS4bGgX...7550&s=0&cc=01)
and everything seems to work except the sound.
So from my headunit the RCA's are connected to the Amp and the amp goes to the Metra harness to the speakers...
Since i could not hear anything, i got an extra speaker i had and connected it at one of the four outputs of the amp and i could get sound (tried all four outputs with success)
So the problem is between the harness and the speakers...
Does anybody have any ideas??? i triple checked the connections to the harness.. connected the right outputs of the amp to the right inputs that the metra harness cable codes describe... I have done a few other installs for other friends with no problems... i have no idea what it is...
please help!!

 

now that i saw th threads again, i did not connect the antenna lead... does it even matter??? i mean for sound purposes... wouldn't i be hearing something??
By the way i forgot to mention that i took out the bose subwoufer and bose amp... please help!

 

Question, since you got a your own amp, did you by-pass the bose amp in the trunk? If you hooked up your new amp using the metra harness at the head unit location then it is going thru the bose amp in back. If your going to use a aftermarket amp and stock wiring you have to hook up the speaker leads from you new amp in the trunk area. The bose amp is under the black foam next to the tire. Paul350z has some good pictures of this.

 

Oh and make sure to connect both antenna lead and Oem bose amp lead to the new head unit.

 

ok.. i had same problem, so i end up going to bestbuy and
got a metra smart cable. if you dont have smart cable, try that..

 

james, thanks... i will try to connect thru the trunk then not the metra harness.

Why do you say i need to connect the antenna lead and the oem bose lead to the new head unit?
The antenna is not motorized, and the bose unit is now obsolete... is there another reason?


behjjeh: i have not seen the "smart cable" but i will try first what james recommented. I also got new speakers so i am gonna try to install these and if i find problems i will just rewire everything! thanks for the reply!

 

Your Welcome
The antenna on the 350a has a powered amplifier witch needs to be connected or you will not get any radio signal. When you take the panels off in the trunk on the side of the antenna you will see the silver box nere the ant.
I was meaning, If you deside to use the bose unit instead of your new amp, that you would have to connect the power lead to the new head units remote on wire. But since you have the new amp and by-passing the bose unit you do not have to connect that lead.

 

cool! ok then i will only connect the antenna blue lead to the harness and forget about the bose connections then!
i appreciate all the help.. saw some tutorials in here of how to open door panels so i will put my own cable and speakers... then it should all sound nice
once again thanks for the help !

 

Here is a quick sketch i did of the layout of the boses in the Z

 

great! finished and everything works now! you were right on the speakers so i decided to do my own cabling and the result is awesome!

 

I am glad you got it all working and that i was able to help. Enjoy the new sounds
