Angel with a wild side: A4 Leave a Comment / Audio, Custom Fabrication / By Ultra Auto Sound This beautiful Audi A4 got into the wrong hands (I wont name any names). These people used the wrong type of wires, low quality products, and did a horrible install......and the worst part is......let the customer leave dissatisfied. The sound was so horrible that the OEM setup sounded much much better. The owner found us on google and liked what he saw. We removed all the old wiring, rewired everything properly, added our JL XD600/6 amplifier. Wallah! happy Mr Customer. JL Audio amp and chache mounted on custom made board. Used top quality signiture RCAs'. Best part is hearing this thing! WOW! Amp hidden in Left rear compartment. Nobody will know about this story…….. hahaha People come to ULTRA AUTO SOUND because it is done right!
