Fitted a couple of Kenwood 4in Speakers in the rear bins.
To be fair I wasn't expecting a huge amount of difference to the 6.5in upgraded Infinity ones on the front, if only because the Kenwoods were cheap and they sit very close/almost touching the seats!
Now while I'm no big, can't hear yourself think, mind numbing, baseman, am more than pleasantly surprised with noticeable better overall sound.......
The Temptations sound even better, even on lowish volume!!!
