Mercedes-Benz C43 AMG Speaker FAQ

What speakers should I replace first in my Mercedes-Benz C43 AMG for the biggest sound improvement?

Replace the front door panel speakers first. These 6.5-inch coaxial or component speakers handle most of your music's frequency range and sit closest to your ears. The front speakers typically receive 75-100 watts RMS and cover 80Hz-20kHz. Since the Mercedes-Benz C43 AMG positions these speakers at ear level, upgrading them creates the most noticeable difference. The rear speakers can wait - they mainly fill in ambient sound.

Can I install component speakers in all Mercedes-Benz C43 AMG locations that show "coaxial, component" options?

Yes, but you'll need to plan the tweeter placement carefully. The front door panels accept either coaxial or component 6.5-inch speakers around 4-ohm impedance. Component systems separate the tweeter from the woofer, which might work well since some C43 AMG models already have dashboard tweeter locations. The rear deck lid spots also support components, though most people stick with coaxials there. Component speakers typically offer better imaging but require more installation work.

Why does my Mercedes-Benz C43 AMG have different rear speaker sizes depending on the model?

Mercedes changed the rear deck configuration between model updates. Earlier models used 5.25-inch speakers with full-range, coaxial, or component options. Later versions switched to 6.5-inch speakers, probably for better bass response below 100Hz. The 5.25-inch speakers might handle 40-80 watts RMS while the 6.5-inch versions could take 60-100 watts. Both sizes work fine for rear fill duty in the C43 AMG, though the larger speakers provide slightly more low-end punch.

What's the purpose of those small 4-inch rear door speakers in my Mercedes-Benz C43 AMG?

Those 4-inch coaxial or full-range speakers supplement the main audio system. They're positioned to create ambient sound around rear passengers, handling maybe 20-50 watts RMS and covering roughly 120Hz-15kHz. Think of them as fill speakers rather than primary drivers. The Mercedes-Benz C43 AMG uses them to create a more enveloping soundstage. You could upgrade them for slightly better clarity, but they won't dramatically change your overall sound quality compared to the main front speakers.

Should I keep the dashboard tweeters when upgrading my Mercedes-Benz C43 AMG speakers?

Depends on what you're installing up front. If you're putting in coaxial speakers, the dashboard tweeters might create frequency overlap around 3-5kHz, potentially causing harsh highs. Component systems work better with existing tweeters since you can adjust the crossover points. Some people disconnect the dashboard units entirely when running new coaxials. The 1-inch tweeters in the C43 AMG dashboard probably handle 15-25 watts and extend up to 20kHz, so test different combinations to see what sounds balanced in your specific setup.
