My HU has 4rca outputa and a subwoofer output. now my is only 2
channel (only want for sub).
My question is do i need Y for sub output to go into amp and if so
can i still use the other wires (not rca) to run 4 cabin speakers?

Um, what?

Your post hurts my brain, but I think I've deciphered it.

You appear to be saying that your deck has one sub output jack but your
sub amp has two inputs? If so, whether you need a Y-splitter will
depend on the amp itself and how you wire it. If you're running it
stereo feeding two subs, then you will need a Y-splitter, unless the amp
has a "mono" mode. If you're running one sub and/or running the amp
bridged, then you probably don't (but again, this will depend on the
specific amp.

And yes, you can still use the speaker outputs on the deck to run the
cabin speakers.
