So... due to a major flaw in the BMW Z4 design, I ended up with about 3cm of water pooled in the compartment that holds the battery and the amp (leaks through the trunk
). Obviously, this has royally messed up the amplifier. A few channels of audio have gone out, and I've taken the amp apart once (there was some slight charring on an IC, a few surface mount resistors and caps, and a transistor. I'm gonna poke around at it today with actual test equipment and see what I can find.
I've never really done failure debugging like this before, so I'm looking for some tips (or guides somewhere) that would be helpful to read for debugging. All I could think of is taking individual components off, looking up the specs, and testing to see if they work as designed. Obviously caps and resistors I can probe to see if they're working properly.
I'll get model numbers and pictures once I get home and take the amp apart again.
