Audi Coupe Speaker FAQ

What speakers should I replace first in my Audi Coupe for the biggest sound improvement?

Replace the 6 x 9 inch rear deck speakers first. These handle most of your bass and midrange output - around 80% of what you actually hear. The rear deck location gives you 15-25 watts RMS capacity typically, maybe more with aftermarket options. Front door 5.25 inch speakers come second since they affect vocal clarity. Those tiny 3.5 inch dashboard speakers? They're mostly for high-frequency fill and won't make much difference until everything else is upgraded.

Can I install component speakers in the front doors of my Audi Coupe?

Yes, the front door panels accommodate component systems. You'll need separate tweeters though - probably mount them in the dashboard area or door panels if there's space. The 5.25 inch opening handles most component woofers just fine. Crossover networks might need creative mounting behind panels. Check impedance matching - most Audi Coupe systems expect 4-ohm loads, though some handle 8-ohm speakers. Component separation gives you better imaging than coaxials, especially for the driver position.

What's the difference between coaxial and triaxial speakers for the rear deck?

Triaxial adds a super tweeter to the standard tweeter/woofer combo - supposedly extends frequency response up to 20kHz or higher. Whether you'll actually hear the difference depends on your ears and music type. Coaxials might sound more balanced since there's less phase interference between drivers. The 6 x 9 inch rear deck location in the Audi Coupe works well with either type. Power handling ranges from 20-60 watts RMS typically. Triaxials can sound harsh if the super tweeter is poorly designed.

Should I keep the original 3.5 inch dashboard speakers or replace them?

Depends on your budget and expectations. These handle roughly 4000Hz and up - mostly cymbal crashes and vocal sibilance. Original Audi Coupe dashboard speakers probably run 5-10 watts maximum. Aftermarket 3.5 inch options might give you slightly better clarity but won't add bass or significant volume. If your rear deck and front door speakers are already upgraded, then sure. Otherwise it's like polishing the trim before fixing the engine. Full-range 3.5s work better than coaxials in this small size.

What impedance should replacement speakers be for my Audi Coupe?

Stick with 4-ohm speakers for maximum power transfer from the factory amplifier. The original Audi Coupe system likely expects this impedance across all positions. Using 8-ohm speakers reduces power output by roughly half - your 20-watt system becomes 10-watts effectively. Some people prefer 8-ohm for "cleaner" sound but you lose volume headroom. 2-ohm speakers might damage the amplifier over time. Check with a multimeter if you're unsure about original speaker impedance, though 4-ohm is the safe bet.
