Audi Fox Speaker FAQ

What speakers should I upgrade first in my Audi Fox?

Replace the front door panel speakers first. The 6.5-inch front speakers handle most of your stereo imaging and vocal clarity. You'll notice the biggest improvement there since you sit closer to the front stage. The rear deck speakers can wait - they mostly fill in ambient sound. Start with quality coaxial speakers around 50-75 watts RMS for the fronts. The Audi Fox front door panels typically accept both coaxial and component setups, so you have flexibility.

Can I install component speakers in my Audi Fox front doors?

Yes, the front door panels should accommodate component speakers. You'll need to mount the tweeter separately - usually in the door panel or dash area. Component systems typically offer better sound staging than coaxials because the tweeter placement is optimized. Look for components with crossovers around 3-4 kHz. The woofer will fit the existing 6.5-inch opening. Just verify your Audi Fox has adequate depth behind the door panel for the component woofer's magnet.

What's the difference between coaxial and full-range speakers for the rear deck?

Full-range speakers in the Audi Fox rear deck position work fine for fill sound. They're basically coaxials without the separate tweeter mounted on top. Coaxials give you more high-frequency extension with that tweeter. The 5.25-inch rear location doesn't need aggressive tweeters anyway. Full-range speakers might actually sound more natural back there since harsh highs from the rear can interfere with front staging. Either type works - depends on your preference for rear presence.

What impedance should I use for Audi Fox speaker replacements?

Stick with 4-ohm speakers for both front and rear positions. Most aftermarket car speakers are 4-ohm anyway. Your head unit expects this load. 8-ohm speakers will play quieter and might not match well with your amplifier if you add one later. The Audi Fox electrical system should handle 4-ohm loads without issues. Check your head unit's power output - usually around 15-25 watts RMS per channel for factory units from that era.

How much power do the Audi Fox speaker locations need?

The 6.5-inch front doors can handle 60-100 watts RMS comfortably. The 5.25-inch rear deck speakers work well with 40-75 watts RMS. Don't overpower the rears - they're mainly for ambiance in the Audi Fox setup. If you're running off head unit power only, any decent aftermarket speaker will be an improvement. Factory speakers from that era were maybe 10-15 watts. Modern speakers are much more efficient, so even 20 watts from your head unit will sound significantly better.
