A couple of days ago, parked at a stop light, I suddenly started to hear LOUD clicking and crackling noises. The radio was off at this point. When I turned it on, it would suddenly come on at high volume and then go silent. This continued intermittently for a while and then the radio started to function normally.
Now, every time I start the car, I get these loud clicking noises, and the radio comes on at full volume for a brief second, and then dies. There is silence for most of the ride, except for the occasional clicking noises. If the radio is in the "ON" position, the clicking noises are interrupted by a brief output from the radio (at full volume) and then back to silence for a while. The voice navigation works normally.
Any ideas as to what this could be? I am afraid it is my amp which I hear is $1400 for my 2001 LS 430. If it is the amp, do I have any cheaper alternatives?
Thanks for any help on this.
