For the first time I choose not to fit aftermarket & went for the Bose as I have never spent this amount on a car before. Must say though it is so top heavy it hurts my treble is down to it's minimum & yet I have still been able to blow the centre speaker. One thing thou is it's a lovely clear sounds but I expected more from Bose. Settings. Treble - max minimum Mid - Half minimum Bass - Half maximum Getting replaced under warranty.
