I've got 2 pairs of diamond Audio HEX S500s components for front and rear, each needing 150 RMS and having impedance 4 Ohms.

I also have a Diamond Audio D5 600.2 Amp which I'm hoping to use. The amp is rated at 150 RMS X 2 @ 4 Ohms, 300 RMS X 2 @ 2 Ohms.

Would it be possible to connect each right and left pair of components in parallel, showing a 2 Ohm load to each channel of the amp and getting the 150 RMS needed for each component?

If so, will sound quality suffer, as I've heard that the THD is much worse at 2 Ohms than it is at 4 Ohms.

This is driving me mad so please HELP!
