How many RCA Outs needed on headunit?

It can be said in a few different ways... You need 3 sets / 3 pairs / 6 individual RCAs.

The 3 sets consist of:
- front left & front right
- rear left & rear right
- subwoofer left & subwoofer right

lolwat?

2 pre outs for a couple of amps and a subwoofer pre out.

So the front speakers and the sub runs of the 4-channel amp. Well in that case 2 sets of RCAs would be ideal, but 1 set with some splits would still work fine too.

You should be able to find a head unit that has 3 pairs of RCA out puts.
The sub-out option is very handy it lets you control the subwoofer from the deck frequency,slope. Very handy.
You can buy Head units that have 2 pairs of RCA and one set can be a sub-out.

So would this one work?
RCA MALE to 2 x FEMALE Audio Video Splitter Cable 15cm (eBay item 290526099556 end time 02-Feb-11 14:27:19 AEDST) : Electronics

Thanks for your help and sorry for NOOB questions!

You don't want to split the RCAs as then you can't adjust the sub and speakers separately. You can set the amp's levels so it sounds fine but you'll get music that needs less or more sub and won't be able to adjust it properly.

Yeah I agree with StoneX here, now that I've slept and I'm not ridiculously tired, I think two sets of RCAs would be best, than you can fade to front or back to adjust the bass.
