Alright my current system is Two Pioneer A-series 3-Way 6x9 speakers running perfectly off of the radio power. And i just installed Two 10" Kicker Cvr Subs powered by a Alpine MRX-M100. My problem now is that when the music is playing the Subwoofers dont hit or make sound much at all. Everythings wired correctly, when I hook the wires up to my friends Subs his work great. But i was trying to adjust the knobs and they say Gain lvl, Bass eq, Subsonic, LP Lvl. Nothing i did made them sound better so i put them all back to 0. Does anyone know what the problem could be?
