Okay, I may be asking a completely stupid question here or maybe not but basically I have concern for my system. I previously had an older model Alpine head unit which made my sub sound really good. It's only a 10" Kicker but it sounded real damn good. ANYWAYS, my Alpine head unit kicked the bucket so I purchased a brand new JVC to use. Here's my concern: when I had my sub connected to the Alpine it sounded really good but when I hooked up the JVC it didn't sound as good as before. Why is this and what are my options for getting the most out of my sub?
