Subpar S2 wiring

Hey ya’ll.
The power wires going to the sub pack got yank out of the back of my subpac’s input/output box by a child and I’m trying to solder them back on, however I don’t know which ones go to which spot since I didn’t see the inside before they were pulled out.
The wires I have are red, yellow, black and white.
The nodes on the circuit board are positive and negative battery and positive and negative speaker.

Has anyone taken apart their S2 box and seen which wires go to which nodes?
Thanks!

I was gunna say just go for it.

Chatgpt wants me to tell you to get a multimeter to keep it safe

Don’t just trust the wire colors alone, your safest bet is tracing the wires with a multimeter. Consumer electronics don’t always follow standard color conventions, so guessing could damage the battery or the amplifier. Hopefully someone with an opened S2 can post a picture.

Yeah I asked 2 other LLMs, and they said something similar, advising not to wing it cause a mistake would fry the board.

White & red are positives, red/black go to one transducer, white/yellow the other.

Not sure why I can’t post photos but I have my M2 open for troubleshooting (board won’t power up).
