JBL is a great brand that often get overlooked. Find a 750-1000 watt mono amp that is 1 ohm stable on them and let em wang. You should be happy for the power.
yes there are pretty good i had an old 300 watt 15 i think it was a house 15 but never the less i put a 760 pioneer at 1 ohm and it hit ok for what it was.
