Selecting a Speaker
Speaker Requirements
There are two basic speaker requirements for TTS:
• Only one speaker can be connected to the MCP110 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.
Some 6-ohm and 4-ohm speakers may work. We recommend testing prior to performing
installation.
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 for text-to-speech.
• If you are using a vehicle’s audio system 8-ohm speaker, see Option 1—Connecting to an
Existing or Shared Speaker on page 8-3.
• If you are adding a dedicated speaker for TTS, see Option 2—Connecting to a Dedicated
8-ohm Speaker on page 8-6.
