I got two audio amps in the mail today, but they didn’t come with any wires for the speaker outputs, I really need some help. I provide some images of the amp. The amp is a Namco V257 bass amp pcb. I can’t find any information for this and I was hoping someone knows how this amp work, pin outs for the speaker outputs.

Thank you so much, have any idea what type of 12 pin connector this uses?
 
Ok, thanks to everyone for the help, just in case, for future reference, I’ll post pictures of the pin outs.

I’m sorry to necro bump this, I wondered if anyone knew what J1 was for on the 257 Bass Amp?
 
Looks like it's just a parallel input connector, if you wanted to use a 4-pin connector instead of RCAs.
 
That’s what it looked like to me too, has anyone any idea how to wire a volume pot up to it, should be ground outside lug, input middle and output outside I think right?
