Though I can't differentiate between many brands of speakers (Illusion , RF , Hertz, Rainbow, Boston etc SQ speaking - my ears are bad) I can say that the installation is NEAT. One point which I didn't like is the mounting od tweeter ,you could have mounted them on A pillar using fibreglass and it would have looked neat (though cannot judge about the visibility afterwards). Did you damp the spare wheel-well too? Also if you are using parcel tray then damp it using smal rubber tubes to prevent vibration. Love the feature to adjust HPF and LPF through the HU but it can be a pain to adjust it often .
Also did you opt for navigation box?
