How to get the most power out of my sub

Each sub is 300 watts rms so you need a total of 900 watts. When it comes to speakers and amps you always want your speakers to be able to handle just a little more power than your amp puts out. I think 1760 watts is a little too much power for your subs. But if you want to run more power than suggested I would look at the Audiobahn  A12001D it’s a very strong amp http://www.audiobahninc.com  it puts out 1200 watts rms @ 1 ohm. But I would suggest the JL.
