Hi guy's just to let you know i had a 1999 td5, i wanted to put an uprated sound system in my car, but the audio guy said you can't put after market system on the land rover amplifier, the only way you can do it is by replace the lr amp, so i should speak to your local audio specialist and see what they have to say. Sorry to be the bearer of bad new's.
Best of look.
