  Creating a radio that can survive the harsh environment and abuse within construction equipment must be hard to do.  As of today, you only have 2 or 3 versions at best to choose from.  One is the factory, usually the most expensive.

A heavy duty 12 or 24 volt radio.
  At just over 5 lbs, this lightweight cube packs a real punch. You are cranking out 50 watts x 2 when used at 12 volts and a whopping 110 watts x 2 in a 24-volt application, more than enough power to get over your cab noise.  Yes, you read it right, this system will work both 12 volts and 24 volts.  TREMOR is perfect to use in your excavator, wheel loader, dump truck, UTV, ATV, RTV or any machine you want a hidden radio with Bluetooth.
How is this BLACK BOX going to solve your radio problems?

  The first and probably most noticable is the lack of a radio.  There is no radio installed in this BLACK BOX.  No radio has two advantages.  No radio to break and no antenna to replace ever.  So what good is this thing?  This thing is a heavy-duty 12/24-volt smart speaker system with advanced 5.0 Bluetooth technology. The operating range is almost double of its older processor.  Connection is amazingly fast.  There is no limit to the number of pairing devices this unit can handle.  In todays world streaming is first choice.  Everyone has a smart phone.  Streaming is so easy and convenient.

  TREMOR excels in streaming because of Bluetooth 5.0.  Whether you are using an APP or just streaming downloaded content, this thing is smoking.  If streaming is not your thing, you can use the 3.5mm direct-connect approach with the AUX input.  AUX is usually the same connection as your headphones.   If you are using your phone as your source for the AM/FM tuner, this method works great since most phones use the headphone cable as the antenna for AM/FM reception.
