I get a aftermarket headunite-JVC KW-HDR81BT
also I get the Metra 70-7551
I do the research on how to wire the hardness, but I am still confused on some parts

from the Metra 70-7551:

where should i connect the "AMP TURN ON (12V+)"(blue with white strip)
"AMPLIFIER GROUND"(black with white strip)
"POWER ANTENNA"(blue)
"CHASSIS GROUND"(black)

from the JVC headunite

there is one for auto antenna, where should i connect this?




thanks for helping!!!!

 

Chassis ground gets grounded to the metal of the vehicle.

If you don't have the bose amplifier, don't worry about amp turn on or amplifier ground.
Connect power antenna to auto antenna.

 

i have the stock bose amplifier......so what should i do

 

If you have the stock bose amplifier, you have the wrong wiring harness.

Get a PAC ROEM-NIS2 and start over.

 

Hi thanks for all your reply.
Wrathernaut didn't you use the metra 70-7551 on the bose amp in your post?

so I should get the PAC ROEM-NIS2 instead of metra 70-7551?

 

Yes, I did use it, but most people haven't had good luck using it. I used it in mine to confirm/deny that it was possible that it'd work, but enough people wired according to my video had bad results, so I don't recommend it at all anymore.

Since I replaced the POS waste of space sound-quality killing bose amp, it didn't matter that I used the 70-7551.

 

Hey Wrathernaut, did you actually replace the Bose amp with another or just delete it out?

 

OK, thanks you
I just order the PAC ROEM-NIS2
waiting for it!!!

ha

 

I deleted it with extreme prejudice. Removed from the car, disassembled and thrown in a box somewhere.

The only bit of factory audio remaining in use in my car is the wiring to the front door speakers.
