Subwoofer varies by day
 

Hey guys,

So I have a full JL audio setup in my trunk. There are days when they hit so hard my mirrors are useless and the sound is incredible. Then there are days when it sounds good, but nowhere near as loud. Now ive checked every connection and everything is tight. nothing has really changed meaning amount of stuff in my trunk or whatever. Any ideas? It only bugs me bc sometimes Ill have someone in my car and I wanna show off a bit and it just falls on its face. Today is a good day, I rattled the lights in my office just being parked outside when I was checking connections.
