Mercedes-Benz CLS63 AMG Speaker FAQ

What speakers should I upgrade first in my Mercedes-Benz CLS63 AMG?

Replace the front door panel speakers first. The 6.5 inch front speakers handle most vocals and midrange frequencies that you'll notice immediately. Component speakers work best here - around 75-100 watts RMS should be plenty for the CLS63 AMG's cabin size. The front stage creates the primary soundscape, so... that's where your money goes first. Rear speakers can wait unless you frequently have passengers who care about audio quality.

Can I install component speakers in both front and rear doors of a CLS63 AMG?

Yes, both locations accept component systems. The 6.5 inch size gives you decent options. Front door panels typically offer better tweeter mounting positions though. Rear doors might require more creative tweeter placement - sometimes the rear deck or pillar works better than the door itself. Component systems need separate amplification really, so factor that into your budget. Coaxial speakers are simpler if you're keeping the factory head unit.

What's the difference between coaxial and component speakers for the Mercedes-Benz CLS63 AMG?

Component speakers separate the tweeter from the woofer. Better sound staging, cleaner highs. The CLS63 AMG has decent door acoustics that can actually benefit from this separation. Coaxial speakers mount everything together - easier installation, one connection point. Components need crossovers and separate tweeter wiring. If you're not adding an amplifier, coaxials might sound better than underpowered components. The factory system probably pushes around 20-30 watts per channel.

Will 6.5 inch speakers provide enough bass in a CLS63 AMG?

Probably not for serious bass response. The 6.5 inch drivers can handle maybe 50-80 Hz effectively, but that's about it. The CLS63 AMG's cabin is fairly large and well-insulated. You'll want a subwoofer for anything below 60 Hz really. Door speakers should focus on midrange clarity and vocal reproduction. Some full-range 6.5 inch speakers claim lower frequency response, but... physics limits what a small driver can do in a car door environment.

Can I use full-range speakers in the rear doors of my CLS63 AMG?

The rear door panels accept full-range speakers, though the benefit seems questionable. Full-range drivers try to reproduce everything from bass to treble in one cone. Usually compromises everywhere. In the Mercedes-Benz CLS63 AMG, you might get better results with quality coaxials or components in the rear. Full-range works if you're on a tight budget or want minimal modification. The rear speakers mainly provide fill and ambiance anyway, so the speaker type matters less than proper integration with the front stage.
