Is this a Factory Harness or is it made by Aftermarket company, like METRA or Scosche?
>
IF you have the Bose System, it sounds like you are NOT Turning on the AMP, so that is why I have to know "what" Wiring Harnes you are using........
Factory Harness will not Plug into the Acoustik Unit, as it has totally different color wires
What do you have the BLUE or BLUE / WHITE wire of the Acoustik Unit connected to??

Customer: replied 5 months ago.
by a aftermarket brand - Best kits
Expert:  Don 'Mo Lurch' replied 5 months ago.

Expert:  Don 'Mo Lurch' replied 5 months ago.

.
I asked what the Part Number / Model Number of the Wiring Adapter was
I need that info
You posted the Infinity has "Bose"
IF it does, then are you sure you used the "correct Wiring Adapter?
I can't tell you until you give me the info........
Does the Wiring Adapter connect to the Speaker wires of the Acoustik or the RCA Outputs?

.

please respond

Customer: replied 5 months ago.
part number is *****
Customer: replied 5 months ago.
the rca outputs
Expert:  Don 'Mo Lurch' replied 5 months ago.

thanks..........

IF you are using the BHA7551, be sure the BLUE / WHITE wire of the small Plug has Voltage + from the Acoustik BLUE wire with the Unit ON
IF not, connect the BLUE / WHITE wire to the RED wire of the Acoustik
Check your Settings of the Acoustik Unit & make sure the RCA's are turned On or the Internal Amp of the Acoustik is turned OFF, if your Unit has those settings
The BHA7551 is "Plug & Play" "IF" you have "Bose System"

.

Expert:  Don 'Mo Lurch' replied 5 months ago.

need to log off.........
Will be back on in morning.......
Please let me know if you have any luck on this, as I have went over all diagrams & IF this is Bose, then it has to be settings, bad Bose System or Bose AMP Fuse 37 & Fuse 6 or the Bose AMP is not responding

.

Customer: replied 5 months ago.

Expert:  Don 'Mo Lurch' replied 5 months ago.

THANK YOU

will check in morning.......

Expert:  Don 'Mo Lurch' replied 5 months ago.

did you find the issue?

.

Customer: replied 5 months ago.
2 of 6 speakers are working. Does the ground from the stereo harness need to be grounded to frame?
Expert:  Don 'Mo Lurch' replied 5 months ago.

It is always a good practice to Ground the Radio Ground to a known good Frame Ground
Which 2 speakers are working?
As it sounds like we still have a AMP issue......IF it is Bose

Customer: replied 5 months ago.
The front and middle right speakers.
Customer: replied 5 months ago.
it is a bose
Expert:  Don 'Mo Lurch' replied 5 months ago.

was the Factory Unit working prior to this installation?
What was done to get the sound to come out of these, since you had posted there was no sound?

Customer: replied 5 months ago.
Factory unit working. Connected blue/white wire to red acoustic wire.
Expert:  Don 'Mo Lurch' replied 5 months ago.

What is the BLUE wire on the BHA7551 big plug connected to?

Customer: replied 5 months ago.
Auto ant of the acoustic.
Expert:  Don 'Mo Lurch' replied 5 months ago.

Is the BLACK / WHITE wire connected in the small plug to BLACK or Ground?

Customer: replied 5 months ago.
Black/white wire connected to black wire (gnd) from acoustic.
Expert:  Don 'Mo Lurch' replied 5 months ago.

IF you have not changed any speakers & have the BHA7551 wired directly to the Acoustik color for color, and have the RCA plugged into the Front & Rear of the Acoustik, you may have to opt for the PAC Adapter LP7-4
http://www.pac-audio.com/productDetails.aspx?ProductId=1189

as the Bose System in this year had issues of converting Signals from some Units
That is the only reason I can see this does not work, because you have verified everything else
The only other thing I would do is plug the Bose Unit back in to make sure everything is working

hi i have put in the lp7-4 and still only 2 speakers are working and i have to turn it all the way up on my radio in order to listen to it comfortably
Expert:  Don 'Mo Lurch' replied 5 months ago.

have you reinstalled the Factory Radio to see if all works?

Customer: replied 5 months ago.
Expert:  Don 'Mo Lurch' replied 5 months ago.

yes
??

IF the Factory Radio works ALL, then you have connection issue with the LP7-4 or the Acoustik Unit is NOT producing sound thru the RCA's.....
Be sure there is Voltage + on the YELLOW & RED wires of the Acoustik Unit with Key ON
The LP7-4 is a simple hook up which you would cut the RCA plugs off of the LP7-4 & connect to the Speaker Outputs (not rca) of the Acoustik Unit
Then you would connect the BHA7551 RCA's to the LP7-4, & plug in the BHA7551 to the Factory Harness........
IF the Factory Radio works, then you need to go over your wiring, as I cannot see what was done

Expert:  Don 'Mo Lurch' replied 5 months ago.

your original question was;

"it turms on and works just fine nut no sound at all please help"

I posted what should be done & you have since said there was "sound" out of "2 speakers"
the rest of the speakers has to be a wiring issue, if your Factory Radio still works

At this point, you may want to take it to a local Car Stereo Shop & have them take a look......
