yes, they are brand new. the problem is that I'm not in the US.
I just said the DIN, because reading the whole 4 pages of this forum, my problem seems the same as everybody else. The right ch sends signal but with a very low volume (Test was: disconnecting left ch, connecting only the right ch and turning on the volume all the way up, and I could here sound out of it.).
Maybe the problem could be in the amp inside de sub?
thanks.
