Anyone have experiance installing a amp/sub to the stock deck on one of these? Its an 03 4.4 with business cd stereo (non dsp, no nav) 6 cd changer. Having hell of a time installing high level converter and 2 channel amp. Cant seem to find any info on the net either. I want to tap into the stock system, but doesnt work, the plug is 12PIN, according to x5world.com i should tap into 11 and 12 or 5 and 6... but its a no go. what am I doing wrong? btw I am connecting the wires like this. 5 - into L rca, 6+ to R rca, then into the hi low converter. (i cut one end of the rcas so i could attached the tapped wires)

 

i used a new cd deck to power my system in my x5
are you in the back of the amp on the left side of your truck ???

 

yes sir...
