I own my own small business repairing car amps, I'm the cheapest in the USA and offer so many services no other car amp repair business offers. I just had one of these Panasonic SB-WA310 sub modules givin to me I thought I'd do the same when I got a chance. So I just traced the wires and solder traces and found the turn on wire to turn the yamaha sub module on. I have degrees in electronics engineering and already have done this witha yamaha subwoofer surround system simular to this but it had a Svideo type looking plug to connecting it to the receiver. I am an electronics engineer and have designed 2 mono class D aamps. I want tyo do the same thing and use it for my computer or for my mothers computer as a subwoofer. Hopefully somebody with electronics knowledge could help me out. Then that would be our input, but like I said we would still need to connect other two pins, in order to turn on the sub-woofer function, here's where I have the problem, I don't know which two pins I need to connect to switch the sub on. The number 17 says Sub In, so I believe this is the positive then we have to use one of the ground pins. Since I don't have the original unit to connect it to, I think two or more of the pins have to be connected together (to act like a switch) to make the sub function to turn on.

I don't have the breakout cable (if I did it would be fairly easy to identify them properly) I just have is the sub-woofer itself. Here's the pin layout: 01 - DVDAC2 02 - DCDET 03 - DVDAC1 04 - SYS6V 05 - MUTE_H 06 - DGND 07 - FRONTR - IN 08 - SUB+B 09 - OUTPUT_GND 10 - OUTPUT_GND 11 - FRONTL - IN 12 - SURR_L - IN 13 - GUARD_GND 14 - SURR_R - IN 15 - CENTER - IN 16 - GUARD_GND 17 - SUBWOOFER - IN 18 - GUARD_GND 19 - PCONT 20 - FREQ_HOP 21 - SYNC 22 - FL1 23 - SUBAC1 24 - FL2 25 - SUBAC2. This Service Manual can help you repair, recover, restore, fix your Panasonic SB- WA3. On this page you can download Panasonic SB- WA3. Please keep this manual for future reference. Actually I've already tried different ways to connect it with the help of the pin layout (see below), with no success.ĭetails SB-WA100. Does someone know hot to connect the Panasonic sub-woofer model: SB-WA310 (no breakout cable, just the sub itself), to any receiver with a regular sub-woofer output? I'm aware that the unit is gonna have to be opened and some soldering will have to be done as well.
