just got a new CD deck (Alpine CDA-9807) to replace my stock tape deck in my 94 Pathfinder. The volume levels range from 0 (off) to 35. 3 is loud enough for normal listening. By the time I reach 6, it sounds like my (stock) speakers are going to shred soon. Another way of looking at this issue is that the difference between volume settings is too drastic... probably at least 5 decibels. That doesn't seem right. I'm new to car audio. Is this a common problem? What can I do to fix it? It seems too drastic to be a speaker sensitivity issue.
