[QUOTE="sroking08, post: 8706182, member: 679817"] 2011 Audi A5 with concert stereo I bought a line out converter and hooked it up using the rear speaker inputs. Everything works fine except when I start the car the subs freak out and pulse full blast for a few seconds... I hooked the remote turn on wire to a fuse in the rear. I remember trying to get the rear back up camera to work using a trigger wire and all it would do is glitch out. To get it to work I had to use the radio out's specific trigger wire. Maybe its the same sort of issue? I tried a couple different fuses in the trunk, passenger side. When you first put the key in the car the subs just THUMP like they are 80% volume for about 4 seconds. I cant figure this car with this canbus electronics.... Is there a fuse that gets power a few seconds after the car has started? The amp is getting power to fast I think. Wonder about a relay. Anyone else have an issue like this? Ok this is crazy... the electronics in this car/manufacturer are insane... Ive never had so many issues hooking up a rear camera, android audio, line output converters, remote turn on wire... I ordered a relay to delay the power from the remote turn on to the amp so the amp doesnt power on first and prevent the THUMP.. Well today I wanted to hear the subs so I jumped the remote turn on to the +12 on the amp so I could atleast listen to it. When I did that the subs just vibrate loud until I let go... so I unhook the RCA's to see if that helps. The subs stopped vibrating so I plugged one RCA in at a time, first one it didnt do it but the second RCA is started vibrating again. When I say vibrating I mean they are pretty much thumping very loudly fast. So after a bit the amp and subs became stable dunno how... but here is another stupid thing this car does... I was like ok its working now let me close the trunk... As soon as the trunk is closed the subs start to vibrate/thump louf until I open the trunk. They stop as soon as the trunks popped open... same happens if I close it again.... This makes absolutely no sense to me... Ive hooked up atleast 50 car audio systems in my years, never once have I ever came across such a weird vehicle... It is such a basic setup... Line out converter hooked to the rear speakers, 2 channel and polarity hooked up correctly according to wire diagram. 4 gauge +12v power line directly to the battery with a fuse. 4 gauge Negative wire mounted directly the the frame in the trunk. Remote turn on wire hooked to the ligher/acc fuse in the trunk. [/QUOTE]
