Hi,
You could get an EsCos with a 2006, 2007, 2008 and with optional 2040 single cd-player or 10-cd exchanger.
The 2007 radio has an external amplifier. It's mounted behind the dash at the passenger side.
You've got 2 different type of speakers. The basic speakers 20w. dual-cone or the Highpower 2-way (with tweeter) speakers 50w.
If you want to have an 2007 with amplifier, you have to buy the highpower speakers.
I've got the 2007 with external amplifier, highpower speakers, and 10- cd exchanger (mounted in the boot) and the controlpanel is mounted under the radio.
