Hi, I know this is my first post, and I'll understand if you tell me where to go but I'm hoping someone can help me with this, I had a JVC TH-A10R av surround system, the controller recently died and I believe is uneconomical to repair. I certainly don't have the skills to diagnose and repair this myself, I'm happy enough finding dud caps and changing these out but that's probably as far as I could go. Anyway, back to the subject I need some help with:
The system comes with a powered subwoofer that contains the audio amp and speaker connections for the controller, the subwoofer is connected to the controller by an 8 pin din cable, the subwoofer has it's own mains power cable. I would like to use this subwoofer as a stand alone powered subwoofer with a new AV receiver. The pins on the cable are as follows:

Pinout : 0



Pin Name Direction Color Description
1 Left Left
2 Right Right
3 SL Surround left
4 GND Ground
5 SR Surround right
6 SubWoofer SubWoofer
7 Control Control
8 Power on 12 + Power on 12 +

Would it be possible to butcher one one of the cable to allow me to connect this to a standard AV receivers sub out connection, I'm assuming I'd need something to trigger the power on circuit in the subwoofer (pin8?, bypassing this so the subwoofer needs to be manually powered on wouldn't be a problem) plus use pins 6 and 4 for the actual audio signal. I wouldn't need to use pins 1,2,3 or 5. I have the full schematics for both the subwoofer and the controller is any more detail is needed.

Thanks in advance for any assistance you might be able to provide.

I have the same question hope some has some in put

I have a old 8 pin cable that I cut off the bad end. Color of wires as follows: red, black, green, yellow, orange, white, brown and blue with plug connected to shielding. I tried to turn on sub woofer by jumping with AA battery Nothing happens. Not sure which wire is the right one to use, or what turns it on, any ideas. Have a good 8 pin plugs it turns on sub woofer when plug in.
