1000 W RMS @ 1.5 ohm - 4 ohm (11V-14.5V)
THD at Rated Power:
<0.05% @ 4 ohm
>95dB below rated power (A-weighted, 20 Hz - 20 kHz noise bandwidth)
5 Hz - 250 Hz (+0, -1dB)
>500 @ 4 ohm / 50 Hz
According to the chart your amp is only stable down to 1.5 Ohms, so running at .75 Ohms the noise you are hearing is the amp clipping (running more power than it can handle at low ohms)
I would suggest wiring it in series, or you could adjust the gain on the amp until the popping goes away.
Hope this helps.
