TD5 is the same. Had to make a thicker mounting ring for mine.4" AKAIK.
be careful though, not sure if the TD5 is the same, but the 300tdi were really shallow, drivers side is ok, but the passenger hits the wiper motor with normal depth speakers.
I got a deeper mounting ring for it.
Which size fits straight in troops, 10cm or 13cm?
I'm a bit of a thicko when it comes to auto electrics and stereos. So what holes need cutting in the lower dash to fit a speaker? Is it just a hole for the speaker wire or is it a big hole to recess the whole speaker?
So if I fit them on the surface using a spacer, do I just need a small hole for the speaker wire?
