Great installation and pics. My Sony DSX-510BD DAB/FM/bluetooth radio uses a powered splitter for the FM and DAB aerial inputs hooked up to the factory side mounted telescopic whip aerial. Ironically it works great on DAB inside a closed garage but the metal doors probably aid reception. Quite flaky on some stations on our rural roads though. The difficult to access factory radio installation is offset by the Sony Music app on my phone which allows control over most functions via bluetooth and of course music streaming.
I upgraded the footwell speakers with Focal RCX400 units and added a second pair of 3.5" JBL close to my ears, they being the largest the side panels in front of rear wheels could accommodate. Wiring was already there as my Roadsters loom included legacy wiring from 4 seater version, so plug and play. Have always hankered after more, well some, bass though as mentioned above. Final installation of
this sub woofer
here if you're tempted.
