Mercedes-Benz S350 Speaker FAQ

Which speakers should I replace first in my Mercedes-Benz S350?

Replace the front door panel speakers first. These 6.5 inch positions handle most of your vocals and midrange frequencies - you'll notice the biggest improvement here. The front speakers in the S350 typically run around 25-40 watts RMS and 4-8 ohms impedance. Dashboard speakers come second since they affect stereo imaging. Rear deck or door speakers can wait unless they're completely blown.

What's the difference between coaxial and component speakers for my S350?

Coaxial speakers combine the tweeter and woofer in one unit - easier installation, decent sound. Component speakers separate them, giving you better soundstage and frequency response. For the Mercedes-Benz S350's 6.5 inch positions, components typically handle 20Hz-20kHz more smoothly. Coaxials work fine if you want simple replacement without modifying the car. The dashboard 5.25 inch spots... those get tricky with components since space is limited.

Can I use full-range speakers in all positions of my S350?

Full-range speakers work in the rear door panels where the data shows they're compatible. They're designed to handle everything from 80Hz to 18kHz without crossovers. For the Mercedes-Benz S350's front doors, you might lose some detail compared to dedicated components. The 6.5 inch full-range speakers typically need 15-50 watts RMS. Check your amplifier output first - some S350 models have different power ratings.

Why does my S350 have different speaker sizes in different locations?

The 5.25 inch dashboard speakers handle upper midrange and imaging. Limited space up there. The 6.5 inch door and deck speakers provide more bass response and overall volume - bigger cone area moves more air. Mercedes-Benz S350 acoustic engineers probably tested this configuration for optimal soundstage. The dashboard positioning creates a wider stereo image while the larger speakers fill in the low-end around 60-200Hz.

What impedance should I look for when replacing S350 speakers?

Most Mercedes-Benz S350 speakers run 4 ohms, though some might be 8 ohms depending on the amplifier setup. Check your existing speakers first - there should be markings on the magnet. Using wrong impedance can damage your amplifier or give you weak output. 4-ohm speakers draw more current but provide more power. If you're unsure, measure with a multimeter across the terminals. The resistance should be slightly lower than the rated impedance.
