The Audi S4 B5 quattro has got stupid 4" speakers in the front i think, so get some adapters to make 6.5 fit then you can have 6.5 spits in front and 6.5 2ways in rear. You might find if you tune to more bass to the rear you might not care for a sub. More room for kids scooters and shit.
The Original "Sleeper" King: It was intentionally styled with incredibly subtle body changes compared to the standard A4, making it one of the ultimate factory-built factory "sleepers" of the late 90s and early 2000s. #sleeperAudi S4 B5 quattro
