Alright so got my flip out wired up and working I plan on running a subwoofer the stereo has 1 RCA(yellow) labled subwoofer output then there's two RCA's(red/white) labeled line in and then there's two more RCA's(yellow) labled video in and video out

So should I use the red/white RCA for the amp output or run a RCA y splitter through the yellow RCA and then what are the video in and video out used for

 

Use tge subwoofer output to send subwoofer signals.

 

Do I need to use a y splitter so I can have two sub outputs to plug into the amp sub input? And have any idea what the others are for?

 

How many channels is the amp you are using and how many sub woofers are you connecting. For most applications the one output for the sub woofer will be fine. If you are using a two channel amp you can probably bridge it to one channel.

 

Haven't got a amp or sub yet can I only run a mono amp or can I use a splitter been looking at Rockford fosgate p500x.2http://www.sonicelectronix.com/item_67763_Rockford-Fosgate-P500X2.html
