Audi S5 Speaker FAQ

Which speakers should I upgrade first in my Audi S5 for the biggest sound improvement?

Start with the 6.5 inch component speakers in your front door panels. These handle most of the midrange frequencies you actually hear. The Audi S5 front doors typically need 4-ohm replacements rated around 50-75 watts RMS. Aftermarket components will dramatically improve clarity over the factory coaxials. The 8 inch subwoofers in rear side panels or deck lid come second - they'll add the low-end punch missing from door speakers. Skip the tiny tweeters initially unless you're doing a complete system overhaul.

Can I replace the 0.75 inch tweeters in my Audi S5 dashboard with larger ones?

You're pretty much stuck with 0.75 inch or 1 inch maximum. The dashboard mounting points won't accommodate anything bigger without major modifications. Focus on frequency response instead - look for tweeters that extend down to around 2500-3000 Hz to blend better with your midrange drivers. Silk dome tweeters tend to sound smoother than metal ones in the Audi S5's interior acoustics. The small size actually works fine if you get quality drivers.

Why does my Audi S5 have both 8 inch subwoofers and 6.5 inch speakers in the rear?

The 8 inch drivers handle bass frequencies below roughly 120 Hz, while the 6.5 inch speakers cover midrange up to maybe 3000 Hz where the tweeters take over. It's a three-way setup. The 8 inch units aren't true subwoofers though - more like midbass drivers since they probably roll off around 50-60 Hz. Real subwoofers need separate enclosures and amplification. This factory arrangement gives decent frequency coverage but... the crossover points might not be optimal. Component upgrades will reveal how much the stock system was holding back.

Should I upgrade the 2.5 inch center dash speakers in my Audi S5?

These small full-range drivers mainly fill in the center image between your left and right speakers. They're handling vocals and midrange detail work. Upgrading them can improve soundstage width, but don't expect huge bass improvements from 2.5 inch drivers. Look for units with good sensitivity ratings - maybe 88-90 dB - since they're probably not getting much power. The Audi S5 center position is crucial for steering wheel audio clarity. Quality 2.5 inch speakers will tighten up dialogue and reduce that "hollow" sound some factory systems have.
