might be a question for Mr. Luke. For my 1990 325is with factory premium speakers, I purchased a KDC BT645U.
A buddy and I tackled the job over the weekend following most of Luke's audio threads. We removed the factory amp and re-looped the audio to all 6 speakers. The unit functions very well for the first 15 or 30 mins of usage but shortly after the sound would either 1) fade away until the sound goes out or 2) the unit would go into "Protect" mode.
For the first problem, if I crank up the volume manually in attempt to counter the fade away effect, the sound would get worse (static and unclear).
For the 2nd problem, the unit is supposed to go into this mode only if a wire is short but the all connections are well insulated and secure (I tested it by rubbing those wires up on the chassis while the HU is playing) and there was no interference during playback when I was trying to stress out the speaker wires.
Additional info:
-318ti/z3 antenna conversion (should I not connect the power control/motor control wire to the HU?)
-speakers are powered by the head unit.
-factory amp is bypassed and wires relooped (did not need to run new wires from HU to speakers)
-problems appear faster if I actually start the car or when its running (possible power draw issue? should I put in a higher fuse?) and takes a while to appear if the key is in position 1
At first after checking all the wires, I suspect that these problems are occuring because the unit itself is overheating. I mean the heat sink behind the unit heats up to untouchable status after a minute of use and I've heard this is the issue with Kenwood units but any input would help.
