A match made for your backyard
Your audio system doesn't have to be a joke when it comes to sound just because it's situated outside. You can still chill out to rich, crisp music in your very own backyard thanks to the Black Series 8" In-Ground Waterproof Subwoofer and SAM300 Mono Subwoofer Amplifier. This combination of audio units will raise the bass in your outdoor speakers while also staying hidden among its surroundings.

XTernal8 - 8" 300W Outdoor Burial Rated In-Ground Subwoofer (70V Optional)
OSD Audio's 300W 8" in-ground subwoofer brings the boom to your backyard so you can experience amazing surround sound even in the great outdoors. Whether you're hangingout by the pool, cooking on the grill, or hosting a backyard party, the XTernal8 subwoofer supplies the clear, full-range bass you need and the deep low-end coverage, all while standing up to the elements. This subwoofer is designed to withstand the elements with weather-resistant components, and since the sub is buried underground, it provides high-end audio with an elegant, unobtrusive design. It supplements earth-shaking low-end with 300W of power, and the durable 8” polypropylene cone includes rubber surround, not foam, so it will last through years of blistering hot summers and frigidly cold winters.

This OSD Audio subwoofer amp gives passive subwoofers up to 300 watts of power so you can enjoy all the crashes, crunches and car chases with enormous exhilaration. Developed for use with higher wattage passive subwoofers such as in-wall subs that need external power, the Black Series 300W mono subwoofer amplifier provides stable power and enforces the low frequency sound effects.

A Hi James: I do not believe you need to dig up the XSub8 for the winter. I would put a plastic bag over the mushroom cap and tape it shut with duct tape around the stove pipe. But it is your investment and you feel better storing it for winter then go ahead. TimL/6-27-2020
