Mercedes-Benz C63 AMG Speaker FAQ

Which speakers should I replace first in my Mercedes-Benz C63 AMG for the biggest sound improvement?

Replace the 6.5 inch front door speakers first. These handle most of your music's frequency range and sit closest to your ears. The front components typically run around 60-80 watts RMS and cover roughly 80Hz to 20kHz. Since the C63 AMG uses component setups in front doors, you're getting separate woofers and tweeters which... well, that's already better separation than coaxials. But factory units often use cheaper materials. Upgrading these gives you cleaner vocals, better instrument separation. The 8 inch rear deck subwoofer comes second priority - it fills in bass below 80Hz that door speakers can't handle properly.

Can I install coaxial speakers in the Mercedes-Benz C63 AMG front doors that have component speakers?

Yes, but you're downgrading your sound. The C63 AMG comes with separate 6.5 inch woofers and 1 inch tweeters in the front doors. Coaxials combine both into one unit, which means the tweeter sits in the center of the woofer cone. This creates less precise imaging compared to components where the tweeter mounts separately, usually higher up on the door panel. If you install coaxials, you'll need to disconnect or remove the factory tweeters to avoid frequency overlap. Most 6.5 inch coaxials handle 4-8 ohms impedance and around 50-90 watts RMS. The installation becomes simpler though - just one speaker per door instead of managing separate crossovers.

What's the difference between the 3.5 inch center dash speaker options in the Mercedes-Benz C63 AMG?

The 3.5 inch center dash position can take either coaxial or full-range speakers. Full-range means a single driver trying to reproduce everything from bass to treble - usually around 100Hz to 18kHz. These work better in smaller spaces where you can't fit separate drivers. Coaxials in this size typically have a tiny tweeter mounted in the center, but at 3.5 inches, that tweeter is probably under 0.75 inch. The power handling stays low, maybe 15-30 watts RMS at 4 ohms. In the C63 AMG, this center speaker mainly fills in vocal range and dialogue. It's not doing heavy lifting for music reproduction, so the choice between coaxial and full-range becomes less critical than your front door speakers.
