Question about Car Audio & Video
I bought my amp (Alpine MRP-F550) over a month ago, but finally got it
installed only 2 weeks ago. At turn-on, I've noticed it has a LF hum
(70hz?) that slowly damps out (10-40 secs). It happens whether I turn
the key to start or accessory and is not dependent on volume. I also
found that it doesn't happen every time I turn it on, only if it's been
sitting off for a few minutes.
Has anyone experienced this or have any theories as to why it's happening?
