RCA Converter

Hi all,

Finally fitted my amp, but there is quite a lot of feedback through the amp and sub, im wondering if the RCA splitter isnt grounded well. It also comes through next to the +ve from the battery if that could cause interference?

Also where abouts have people taken the 12V remote from for the amplifier, tried to use the back of the H/U to no avail
 
Rca and remote are run seperately from the power from the battery to reduce interference. What headunit/system you got? Ignition live to the headunit should sufice for the remote, unless youve got the 6 cd changer cabasse. The cigerette lighters also a good place to use for the remote.
 
I am using the standard Bluetooth h/u, I did try to stick the remote in the same hole on the harness as the ignition but it didn't work. It only worked when put to the +ve power.

No 6 cd changer :/ removing the 12v socket is it a case of just lifting it out or do I need to remove the plastics for the centre console
