Last week I finally put a system in my car, consisting of a set of focal components on a alpine v12 amp and a JL 12w3v2 on a JL 250/1. It sounds great, but after about 3 or 4 days I have noticed when I have it cranked up my rearview mirror will slowly start to angle more and more down. I had to adjust it 4 or 5 times on my 20 min ride home from work yesterday, and I was just listening to Fuel's Something Like Human cd. I know I don't have that much bass, to be causing problems like this. Basically want I want to know is, Has anybody else experienced this prob?
