I have an A3 8P 3dr with the Concert CD player.
I have subs and amps of all sizes and will be building my own enclosure to suit.
Do I have an Amp and Sub as standard in my car?
And is it easy enough to use the stock stereo and wiring to add in my own amp and sub?
What kit do I need to take from the standard wiring to create RCA and remote?
Assume I will need to run a new power/earth as per normal?
Any info appreciated.
