My girlfriend has an alpine IVA-D900 in her car. This HU has been in this car for years without issue. Just the other day she complained that the sound started going in and out. Then one day she heard a funny noise, and then everything went silent.
Things I've checked:
All 3 amps are getting power, no fuses blown
All wires are tight
There is no sound from any source (ipod, radio, cd)
When I have a little more time I'm going to take my HU out and plug it into her car and see what we get. Didn't have the time tonight to try it. Any ideas?
