Wow you sound truly happy with your new sport car. Great post and thanks for sharing!!! (good memories).
RE the sound. Crank the BASS to the max and you'll finally get 'some' sound coming out of your door speakers. If the treble is too high, the dash'ers simply overpowers the door speakers :/ Regardless, the engine sound is the music you'll listen most often anyway
Enjoy every bit of it and drive safely mate!
