\rHi Joe:
Most Marine systems feature electronics similar to car audio (12 volt). Amplifiers are typically 4 ohms versus the standard home amplifier's 8 ohms. All of our Patio Speakers are rated at 8 ohms as well. The good news is you can wire two pair together in Parallel and achieve a matching 4 ohms to the Amplifier. But I would recommend picking a pair of our Patio Speakers with Sealed (Closed) Enclosure design. Checkout our new AP650 white speakers (we will be adding black model as well). It is also recommended you stow the speakers away when not using your boat.
I hope that helps
