As the title states, I have two 10" Kicker Subwoofers in a box with a Kicker ZX500.1 Monoblock Class D Subwoofer Amp. Everything is like new. Was put in the GT and everyone knows I rarely drive it. Put 3k miles on it in the past 4 years so the stereo has barely been used. $250 takes it all, paid that for just the amp.
