Sony has created their first ever dedicated marine amplifier with the creation of the XM-604M. I’m not certain what “marine amplifier” means, but I’m guessing it means that it can operate underwater. Don’t quote me on that, because I don’t want you to buy the product, stick it in the water and electrocute yourself. Read the instructions, please.

Anyway, this sliver-finished amplifier is suitable to drive full-range speakers and subwoofers. It features 60 watts into four channels at Consumer Electronics Association-rated power.

Sony has recently revealed these products in conjunction with the CDX-HS70MW marine head unit and the XS-L100P5M subwoofer. The Sony XM-604M amplifier should be out by winter for a price of $200 USD.
