Hello guys, please for your help. I bought a new PIONEER DEH-P7700MP today. Well, since I connected the thing with an adapter from VOLVO to ISO the Active Subwoofer is no longer running!!! Think that this is because there is no current on the amplifier of the bass box. I saw that on the original power harness are 9 cables, on the ISO connector however only 4. Are these maybe the cables for the current and the ignition on/off of the sub? Does this know? Must possibly special additional cables be pulled into the ISO connector so that the Active Sub juice has? If someone has experience with it please report that the sub wants to run again. Speaking of, the Pioneer Radio I can only warmly recommend, sound that is pulled out of the original boxes is really great!
