Im trying to hook up my kenwood ddx512 with a metra harness w/ bose

ive hooked up the yellow 12v memory, red ignition, blue antenna, black ground, and orange illumination (as shown) on one end of kenwood harness is the speaker outputs, and on the end of the metra harness is AV outputs... im guessing i use the AV outputs instead of splicing the speaker wires, correct? after doing this, i reconnected the battery, and no power. so im guessing i need to connect another wire someplace...

additional questions are:
do i hook the mute wire to a ground?
what do i hook the parking switch wire to?

w/ the bose connector:
can the black ground be connected to the black ground from the radio? or does it need a separate ground?
the blue/white wire (is a power im assuming? is this for the ignition or battery, or someplace else?)
the purple and turquoise AV terminals connect to...? (in back of radio, av in/out/ speaker sub in/out<--im guessing)

i noticed 4 connectors coming out the back of the OEM radio, and only 2 connectors w/ the metra + bose kit. assuming the other 2 are irrelevant (something to do w/ the cd changer possibly?)

any help would be appreciated

 

got it.... turns out the black ground wire wouldnt work so i connected it to a body ground and everything is fine!

 

Thats because there isn't a ground wire in the factory harness. The stock radio uses the chassis as a ground. The reason the aftermarket harness has a black ground wire is because some vehicle applications do have the ground wire in the factory harness.

 

Please tell me you are not using electrical tape to hold those connections together.

 

lol.. soldering is the best way to go but you can get away with connecting wires via butt splices AFAIK

 

When I installed my DDX512 I just connected the parking brake wire from the harness to the ground connection. Then the headunit thinks the brake is always pulled.

 

Uh oh...I grounded the head unit ground wire to the same twp metra harness ground wires. I get power so I assume that pin is connected somehow to a ground, albeit indirectly. I am getting alternator whine though so I was going in this weekend to check out the ground anyways! I hope after fixing the ground the volume will go up a bit. I have 5V pre-outs and the damn thing whispers when I listen to the radio and barely loud when I crank it all the way up when listening to mp3 dvd's and the ipod!

 

Wrong. Your radio is probably just getting a crappy ground from the chassis of the radio housing. That is why you are most likely getting alternator whine. Ground the radio directly to the body of the vehicle.

 

Like I said it's getting ground indirectly somehow...However...The metra kit is plastic, which doesn't ground very well LOL.

 

Where is a good place near the HU to ground to? And I'm assuming grounding means attaching a ring terminal to the wire and then bolting it down somewhere? (I don't have any extra ring terminals though..)

 

For my SWI-JACK, I grounded it using one of the two bottom screws that holds down the H/U bracket. There are 4 screws below the H/U. The outside two secure the H/U (I used one of these) and the inner two that secure the whtie A/C box.

Those should be a sufficient ground for your use as well.
