so guys any help would be appreciated !!!

 

Do you want to buy a sub box and an aftermarket amp?

 

yes but i need to know how to connect it to the original sound system that came with the car

 

I tapped into the factory RCA (low level) lines going to the AMP in the boot.

I'm not sure if the wiring loom patterns are the same for all the models, but they were similar between A4 and S4 so it's worth a shot for an A3.

theres not enough power to run a sub properly. Get yourself a sub and amp package but you should change the wires to thicker wire for best quality. Its better if you change strero as you'll get clearer sounds. Done the job thats how i know.
