NO!500rms is a lot IMO. the IDQ will sound good off 300, im listening to 2 right now. could you really go wrong with any of those subs?
if your really into car audiom you won't keep it long. That itch to try something new will win!NO!
But that's not really the point, is it? I am trying to open my mind and do a bunch of research before getting the one sub I will be living with for a ling while....
