Hi IcePack, I don't know how old your 4/4 is, my 2015 +4 had all the wiring in the "blanked" radio aperture, I fitted a radio/mp3 player, the wires and holes for the speakers were behind the carpet near the door stays, I did not fit an aerial as they rattle and use a usb with mp3 files on to listen to, Radio £45.00, speakers (high power good quality) £45.00,
Ian
