ya im open to whatever. was icking around the idea of getting a different amp but i dont want to mess with the electrical upgrade right now.. i had 2 12" VMAX going off that 600.1 and it sounded damn decent. i have never heard of RL-i's.. where can i find info on them? i am deff. into SQ over SPL.. i was going to try and get a couple RE SE 10's cuz i loved the 15" but its always fun to try new set ups with new equipment.. any other options you guys would consider off 600watts?? 10" subs only please..
