I'm stuck on what 12" sub i wanna buy for my truck. This will be my first system. Im trying to decide between Skar VVX 12, Sundown SA 12, and the Gcon 12. Ive heard great reviews for all of these. But i just cant decide. They all sound GREAT. I guess the deciding factor will be how durable and reliable they are on top of what other peoples opinions are. Any advice would be great!
