Audi S5 Sportback Speaker FAQ
Which speakers should I upgrade first in my Audi S5 Sportback for the biggest sound improvement?
Replace the 6.5 inch front door panel speakers first. These handle most of your music's midrange and vocal frequencies - around 80Hz to 4kHz typically. The Audi S5 Sportback uses these as your primary drivers, so upgrading them delivers the most noticeable improvement. Look for component speakers rated 50-75 watts RMS with 4-ohm impedance. The factory 3.5 inch midrange drivers in the same door panels can wait. Focus your budget on quality 6.5s first, then consider the tweeters.
Can I install component speakers in the Audi S5 Sportback front doors?
Yes, the front door panels accommodate both coaxial and component configurations. Component systems separate the tweeter from the woofer - you'd use the existing 1 inch tweeter locations in the A-pillar or dashboard. The 6.5 inch location handles the woofer portion. This setup typically sounds better than coaxials because... well, the tweeter positioning improves imaging. Check your crossover mounting space though. Some aftermarket crossovers are bulky and door panels have limited depth behind the speaker.
What's the difference between the 3.5 inch speakers in front doors versus rear deck?
The front door 3.5 inch drivers are midrange-focused, handling roughly 200Hz to 2kHz frequencies. They work with the 6.5 inch woofers in a quasi-component setup. The rear deck 3.5 inch speakers are full-range coaxials - they attempt to reproduce everything from bass to treble, maybe 100Hz to 15kHz. Full-range 3.5s never sound as good as dedicated midrange drivers. The Audi S5 Sportback rear deck positioning also creates weird reflections off the glass. Replace front 3.5s only if you're doing a complete component upgrade.
Should I replace the 8 inch rear deck subwoofer in my Audi S5 Sportback?
Depends on your bass expectations. The factory 8 inch handles low frequencies down to maybe 40Hz, but it's more of a midbass driver than true subwoofer. If you want real bass impact - those 25-35Hz frequencies you feel in your chest - add a proper subwoofer in the trunk. The 8 inch location works well for replacement though. Look for speakers with high excursion capability, around 100-150 watts RMS handling. Sealed enclosure typically. Free-air mounting limits your options since most quality 8 inch drivers need enclosures.
