after much thought I decide to remove the Tamiya MF03 and replace it with a Servonaut M24 ESC and SM3 sound card with SM-EQ bass\treble boost to tweak the sound to match the trucks cab where the speaker is mounted in the roof. I also replaced the Tamiya 4 ohm speaker with a Visaton 8 ohm FRS 7, also replaced all of the Tamiya LED's with servonaut light boards which give a much better light output, I did not photograph the rear light boards because the were a pain to fit and I forgot to
new ESC and sound module
new front light boards
