Question on sub and amp

Hi, open question to anyone who can help...

I want to replace the subs with a pair of sws-8xi, which I believe are 2 ohms impedance.
I have an old 5 channel alpine amp (MRV-F353) that I want to deploy.

The 4 channels will naturally drive the 4 door speakers, but the mono 5th channel is rated at 150w at 4 ohm (14.4 V). I am planning on wiring the 2 earthquakes in series to achieve the 4 ohm. Is this advisable? will it get loud enough, I have read here that the 8xi are not that efficient.

Any advise/opinion would be welcome.
