I have a 2004 Grand Prix GT that I have wired up with 4 gauge for its first system. The setup I have is a Pioneer DEH-P3900MP head unit, a JL 500/1 v2 amp, and a Kicker L5 10 In a sealed box. Once I got everything installed I played music and the sub was just barely moving and I could barely hear it at all. I went through all the settings on the deck and on the amp and I just can't seem to find out the problem. I assume it's just one thing I'm missing that's throwing it off but I can't figure it out. If anyone has any ideas or suggestions please help me out! Thanks
