Selecting a Speaker
Speaker Requirements
There are two basic speaker requirements for TTS:
• Only one speaker should be connected to the MCP100 for text-to-speech play, otherwise
the volume will be very low.
• An 8-ohm speaker, such as a standard CB speaker or standard truck audio speaker,
should be used for text-to-speech play.
• 6-ohm and 4-ohm speakers may work but should be tested first to confirm oeration on a
known good MCP100 system.
Choosing a Speaker
Text-to-speech works with either an existing speaker (typically, the driver’s side door
speaker) that is part of the vehicle’s audio system, or a speaker that can be added.
• If you are using a vehicle’s audio system 8-ohm speaker, see Option 1—Connecting to an
Existing or Shared Speaker on page 10-4 .
• If you are adding a dedicated speaker for TTS, see Option 2—Connecting to a Dedicated
8-ohm Speaker on page 10-6 .
