By way of an update, the sound system us up and running, now looks like this:








Additional board is an MP1854en thats dropping 3C lipo voltage down to 5V for the Arduino Pro Mini and the Amplifier.


Running one conventional speaker, and one 3w Audio Exciter...





The Exciter is not fully installed yet, but current sound is on this video at timecode 4.50

WoW!   :o

An update.  Really pleased with the sound system build for the 1/10 Aquarama. I'm putting together a second version for my 1/5 Aquarama build, just testing so far...  This time a pair of the Arduino Pro Mini boards running almost same code and sound files, one board to represent each of the V8s in the boat. One board starts then runs, the seconds does same 5 seconds later.  So it sounds like 2 x V8s being started and running.  And I need a lower sound, more bass, so I'm using a pair of PAM8610 amplifiers and pair of Visaton VS-FRS8/4 speakers.  Then have 3D printed a pair of 90mm tubes to direct and further deepen the sound, and its working...  Now making the wiring a little more tidy and will then post a video.  Also adding a vibration motor to simulate the cranking of the motors at startup.
