hi all
i gots a alpine CDA9855 headunit and it's got 3 line out's (both poz and neg)

i have two amps one 's direct RCA cable from bk of amp to headunit (sub amp) the other amp is setup with 2 RCA spliter's doubleing the the one RCA cabel from the bk of the amp to one line out on the head unit (4way amp)
i tryed puting a nother set of RCA spliters on the bk of the head unit to the RCA cable coming from the 4 way but does the same thing nothing

so do i have to go get a nother RCA cable and run it sepret or can u us the spliters

If your headunit has 3 preouts (maybe LeftFront, RightFront, LeftRear, RightRear and sub Left/Right) then you are better off running the RCA cable for each output.

If I've read your post correctly, you have the sub running off one 2 channel amp, and your 6X9s running off a 4 channel amp.

If you want the headunit to be able to fade and balance (front/back, left/right) and adjust the sub output, you will have to run RCA cables.

Its well worth the investment IMO.

Cheers

Ash man is right.
The Manual for the CDA9855 shows that the RCA's are Rear (L&R), Front (L&R) & Sub (L&R) there also looks like there is a switch to select it's mode (could be wrong there)

I got the same headunit.. Run all 3 to use advance features of the headunit.. you get a lot more control of your music

If you are trying not to run lots of leads just run the Front preouts to the speaker amp .. so now the speakers are amped..

Then run RCA's from the line out of this amp to the sub amp (Assuming it has line-out)

done
