Need help wiring my subwoofer?

[trenthonda1 10+ year member]

I have a dual 2 ohm 15'' Fi BL Fully Loaded (2000 watts). And the amp i have is a Rockford Fosgate Prime R1000-1D the specs are (4 ohms 500 watts x 1 chan. & 2 ohms 1000 watts x 1 chan). And i have the sub wired like the pic below. Is the sub receiving the full 1000 watts? And i plan on upgrading to a 1500 watt amp how big of a difference will this amp make compared to the 1000 watt amp?

its not receiving the 1k. amps usually run @70% power.

your wired @ 4ohm according to the pic. and looking at specs your only seeing 500rms before electrical drop and impedance rise . so your the answer to your question is no. need a amp that puts out max rms @ 4 or 1ohm
