Perfectly safe to do so, generally speaking.

That being said, please list exact model numbers of both woofer(s) and amp(s), so we can make sure you won't break anything. You did say you were new to this, that's the only reason I am asking...

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

I'm glad I asked. Those woofers are dual voice coil @ 4 ohms each. You will wire the woofers in a series-parallel for 4 ohms, then bridge the amplifier.

Use the bottom diagram from this page...

This will get maximum power from your amplifier, amd maximum safe load.

It'll MOST likely be labelled right over the amplifier terminals.

Per the manual, which I found online here... Page 5. Look at the amplifier's outermost speaker terminals. The one screw terminal closest to the power connections is the negative, and the one furthest from the power connections is the positive.
