Description

The fully loaded IMSA S9 helmet kit — speakers and an ear bud jack. Cobalt speakers in the helmet plus a 3.5 mm ear bud jack, so you can run either one and switch depending on the event or the driver. Built and tested by SRC.

What comes in your order

  • DIGITAL S9 microphone — built for clarity in high noise, optimized for SRC digital radio packages and works on analog systems too
  • Flex boom — set the mic in the best position
  • Cobalt helmet speakers
  • 3.5 mm (1/8") ear bud jack — plug in ear buds when you want them
  • Straight cord with standard IMSA four-circuit connection
  • Ear buds — only if you choose them below

Choose your ear buds

The kit is $169 on its own. Add ear buds already wired in and the price is added:

  • No ear buds — run the kit as-is, or add buds later
  • Pro Challenger II (Made in the USA) — add $97
  • Semi Custom (Made in the USA) — add $159
  • Custom Ear Buds (Made in the USA) — add $224

All SRC ear buds are Made in the USA.

Fitment

IMSA is a four-circuit system, typically used for road racing and intercom systems. If your car harness is NASCAR (three circuit), order a NASCAR helmet kit instead.

Flexibility is nice

One of the things I love about our setup is the flexibility! With custom earbuds, I can go all-in when I need maximum clarity, or skip them entirely and use the helmet-mounted speakers depending on the car I’m racing. It’s truly the best of both worlds—giving drivers options to suit any situation.
