Pioneer VSX-D512 subwoofer preout doesn't work

[TehRamsus]

Hey
I just bought this tuner. It's works good, almost...
So for some reason i don't get any audio out from subwoofer preout. I tried literally all settings, but nothing. I double checked subwoofer, and it's works.
Subwoofer is "home made". I've used it on my stereo kit, which not offered sub out. Basicly I connected positive and negative to the speakers out.
I don't know what I do wrong.

Thank you for helping.

What amp are you using to drive the sub? A receiver preout will not drive a sub without a power amp between receiver and sub.

Assuming there is an amp in play, the pre out could be bad but not highly likely. Did you tell the receiver “yes” to subwoofer?

Hey, i'm not sure the manufacture of the amp But I have amp with subwoofer, and it's works perfectly. I just tried with other subwoofer (genelec) and same problem.

Yeah, I enabled subwoofer option. Also I tried some difference sound modes like surround etc. But nothing. I'm quite new with these

Ok. Where is the gain(volume) set at on the sub, and where is it set at on the receiver? Did you run mcacc? Or set up manual? What are the rest of the speakers?
I would try some very bass heavy music, as it’s more consistent than a movie, and see what you get.

Hey, It's work now I don't know what is happened, but I changed cable, changed some settings and then I mix some settings in subwoofer. For some reason volume was really low But thanks to help!

That unit is over 20 years old and past its useful life. I did a NET search and find that Pioneer receivers of that era were known for failure of the subwoofer out.
So, if you have initialized the sub out in the menu and set the crossover and sub output, then there is nothing else you can do.
