rear/sub preamp output on sony head unit

[Raging.waters]

On my Sony cdx-gt40uw it has a rca output. However, I believe its a rear/sub preamp output. Will connecting this to my 4 channel amp that powers my 6x8 speakers make them play/focus on bass?

(Side note): I was messaging a Sony representative and he said use the aux port...made my question Sony in general.

If the rca is rear/sub, it is usually selectable in the menus which way you would want to use it. The selection may also open up or unlock specific menus for tuning ( such as how and lpf)

yes, use the single RCA output set in REAR mode until such time that you have a quality head unit. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

sub mode is also likely full range but possible to be level controlled from the HU.

if your amp doesn't have the ability to run in 2ch input mode you will need two RCA Y-adapters (female to dual male).

typically, SUB mode isn't affected by the fader while REAR mode is.

I wasn't able to "select" from the headunit

There are a lot of great head units available used that will give you plenty of features and better overall sound.
