Mercedes-Benz CLS550 Speaker FAQ

What speakers should I prioritize replacing first in my Mercedes-Benz CLS550?

Replace the front door panel speakers first. These 6.5-inch drivers handle most of your vocals and midrange frequencies - where you'll notice the biggest improvement in clarity. The rear door speakers can wait since they primarily provide fill and ambiance. Front speakers typically see more power from the factory amp too, around 20-30 watts RMS, so upgrading here gives you the most bang for your buck.

Can I install component speakers in both front and rear doors of a CLS550?

Yes, both locations accept component systems. The 6.5-inch openings work with most aftermarket component sets. Front doors might be easier since you're already running new wiring for the tweeters anyway. Rear installation depends on your listening priorities - some people skip rear components entirely. Component systems typically need 50-75 watts RMS to perform well, so check your amp situation first.

What's the difference between coaxial and component speakers for the Mercedes-Benz CLS550?

Coaxial speakers put the tweeter and woofer in one unit - simpler installation, decent sound. Components separate them - tweeter goes up high, woofer in the door panel. Components sound better because you can position the tweeter optimally, usually near ear level. The frequency separation is cleaner too, typically crossing over around 3000-4000 Hz. Installation takes longer though... more wiring, custom tweeter mounting.

Do full-range speakers work well in the rear doors of a CLS550?

Full-range speakers can work for rear fill, especially if you're on a budget. They handle everything from about 80 Hz to 15000 Hz in one driver. The sound won't be as detailed as components, but for background music it's adequate. The rear position in the CLS550 is actually decent for full-range since passengers aren't sitting directly in front of them. Consider 40-60 watts RMS for proper performance.

What impedance should I look for in CLS550 replacement speakers?

Stick with 4-ohm speakers. The factory Mercedes system is designed around this impedance, probably delivering somewhere around 25-35 watts to each channel. Going to 8-ohm speakers will reduce power output. 2-ohm speakers might overload the amp... not worth the risk on a factory system. Most quality aftermarket 6.5-inch speakers run 4 ohms anyway.
