At what AC voltage do these subs explode... I am currently running them at 2 ohm and my mono block amp has maxed out at 31 volts with the normal math places my amp at 480 watts "speaker max is 600" but I know that 2 ohm loads bounce a lot if I get a bigger amp will I increase output a lot or will I just be wasting cash I have to lower the output for rock but I feel rap is not loud enuf the sound level is awesome in the built to factory spec large ported enclosure but I dont want to throw anymore money away. If you are running a combo like this let me know what your system is like
