OK. got the metra adapter 70-7551 for my 95 Infiniti J30 and got everything hooked up but dont have any sound. I suppose u just plug the rcas from the harness to the front and rear outputs on the x979 correct? Do I just leave the front and rear speaker wires from the x979 harness alone or do I connect those to something? What am I doing wrong?

but if he wants to keep the bose amp,he shouldnt have to do that,i would think for sure you would wire up the decks speaker outputs into the harness

i think the bose speakers/ amp run at 1ohm which is why i got the harness w/rcas...im getting no sound.

Blue/White needs to go to either power amp turn on off the deck or to an ignition source.

yeah that blue white is coming from teh radio. thats going to need to turn on the factory amp turn on wire.

Nope, no mute is nessasary. Hook up the blue/white wire from the deck to the blue and blue/white wires comming from the factory harness adapter that you bought.

no. stop.


start over. on that 70-7551 you bought, there is one plug with a purple and green rca. these plug in to your rear outputs on your deck, there Also should be Two wires. one for power antenn. and one should be the factory amp turn on.

then the other plug you have there is a black and white rcas, these plug in to your front outputs on your deck. on that same one, there are the normal red/yellow/ etc.
are there any other colors on that too?

tape the speaker leads up coming from teh deck.

the two wire are labeled amp ground and amp turn on. I have the amp turn on connected to the REM from my 801d...is this wrong?

OK. does anyone know if the 801d has a light to indicate its on? A voltemeter I used says it was putting out power.
