The SA-JMS35W-BT delivers waterproof Bluetooth audio for powersports enthusiasts who need reliable sound on ATVs, motorcycles, boats, and golf carts. These marine-grade speakers handle everything from lake days to trail rides without missing a beat.

Each 3.5-inch speaker puts out 20 watts of power through a polypropylene cone driver, delivering full-range sound that cuts through wind and engine noise. The built-in Bluetooth connectivity lets you stream music directly from your phone without running cables through your vehicle.

The 4-ohm impedance and 88 dB sensitivity provide efficient power handling that works well with most powersports audio systems. The frequency response spans 120Hz to 12kHz, covering vocals and instruments clearly. The 1-inch voice coil and long-excursion woofer design ensure these compact speakers move enough air to be heard over outdoor conditions.

Whether you're mounting them on a wakeboard tower, UTV roll cage, or motorcycle fairing, the heavy-duty ABS housing withstands UV exposure and water immersion. The included mounting brackets make installation straightforward on round or flat surfaces.

Each speaker connects via Bluetooth pairing with your device – no additional cables needed beyond power connections to your vehicle's electrical system. The pair comes with mounting hardware and brackets for immediate installation.

These speakers ship fast with Seismic Audio's manufacturer warranty, giving you dependable sound for your outdoor adventures without the premium price of marine audio specialists.

Technical Specifications

Frequently Asked Questions

Will these speakers work with my ATV's existing stereo system?

These speakers connect via Bluetooth to any device with Bluetooth capability, including phones, tablets, and Bluetooth-enabled head units. If your ATV has a traditional wired stereo without Bluetooth, you'll need a Bluetooth adapter or can connect a phone directly to stream music to these speakers.

How loud do these speakers get for outdoor use?

At 20 watts per speaker with 88 dB sensitivity, this pair provides enough volume to be heard clearly over typical powersports noise like wind and engine sounds. They're designed for personal listening areas rather than large crowds – perfect for a small group on a boat or passengers in a side-by-side UTV.

Can I mount these speakers on a motorcycle without drilling?

The included heavy-duty mounting brackets work with both round bars (like roll cages) and flat surfaces. For motorcycles, you may need additional clamps or brackets depending on your bike's configuration. The compact 4-inch dimensions fit most mounting locations without interfering with controls or rider position.

Are these actually waterproof or just water-resistant?

These speakers feature full waterproof construction with sealed ABS housing, not just water-resistant coating. They're designed for marine environments and can handle direct water exposure, making them suitable for boats, jet skis, and open vehicles in rain conditions.

Do I need an amplifier to power these Bluetooth speakers?

No external amplifier is required – these are powered Bluetooth speakers with built-in amplification. You only need to connect them to your vehicle's 12V power system. They'll stream audio wirelessly from your phone while drawing power from your battery or charging system.
