Boss

If you think headphones are your only option on an ATV or a tractor, you need to check out what Boss can do for you. This Boss ATV85B portable sound system with marine-grade speakers uses its heavy-duty Velcro straps to tie down to an ATV rack or a tractor roll bar, so it's easy to switch from vehicle to vehicle. You can power the ATV85B via your 12-volt cigarette lighter or use the included adapter for a more permanent wiring directly to your vehicle's battery. The system's waterproof 8" speakers are built tough, and the system's marine-grade construction means you can even float your boat into the rotation. Mud this Boss up, let it catch some sea spray, it won't matter. Pair your media device via Bluetooth (or plug into the 3.5mm headphone jack), and you'll have inline up/down/play/pause controls to navigate your music, while volume is still controlled through your media device. The built-in amp gives you plenty of power to shake the leaves off the trees if you've got a particularly loud engine to drown ...
