The Rugged Radios PLUS2-STX-BTU rear-seat expansion kit turns a 2-place Rugged STX Stereo intercom system into a 4-place system, adding two Ultimate behind-the-head headsets and two 16-foot intercom cables for the back seats. Rear passengers plug straight into the open rear ports of your existing Rugged intercom — no new intercom needed.

Compatibility

This is the STX Stereo version, matched to the Rugged STX Stereo intercom. It is not wired for Rugged Offroad Mono intercoms such as the 696 PLUS — mono systems use the non-STX PLUS2 version of this kit. Within the STX line, PLUS2-STX-H48/H28 supply AlphaBass headsets and PLUS2-STX-HK supplies helmet kits instead; PLUS2-STX-OTU is the over-the-head version of this Ultimate pack.

FAQ

Will this kit work with my intercom?

It is built for the Rugged STX Stereo intercom. If you run an Offroad Mono intercom such as the 696 PLUS, choose the matching non-STX PLUS2 kit instead.

What is included?

Two Ultimate behind-the-head headsets and two 16-foot intercom cables — everything to put two rear-seat passengers on the intercom.

What is a behind-the-head (BTH) headset?

The band wraps behind your head instead of over the top, keeping a low profile. PLUS2-STX-OTU is the over-the-head version of the same Ultimate headset pack.
