this isn't something i've ever run into, and rather than pulling my whole system apart and troubleshooting it, i figured i'd post in here and see if anyone had run into it before and had a solution...

whenever i first turn my car on, my subs don't play at all. no sound whatsoever. once i turn it up to my normal listening volume, sometimes they'll kick right in, and sometimes there will be a long delay. sometimes they don't cut in at all unless i jack the volume up past what i normally listen to.

what could that possibly be? i was thinking it would have to be something going on with the sub amp... it's an alpine mrd-m650. i know the HU and remote wire are fine because the same wire kicks the full-range 2ch on no problem. but anyways i was just curious if anyone knew what was going on or if there was an easy fix for it.
