Mercedes-Benz S320 Speaker FAQ
Which speakers should I replace first in my Mercedes-Benz S320?
Replace the front door panel 6.5 inch speakers first. These handle most of your midrange and vocal frequencies - you'll notice the biggest improvement immediately. The front speakers get roughly 60% of your listening attention while driving. Dashboard 5.25 inch units can wait since they're mainly for fill and imaging. Rear speakers? Unless you regularly have passengers, they're lowest priority.
Can I use component speakers in all Mercedes-Benz S320 locations?
Yes, but it's probably overkill for rear positions. Component speakers separate tweeters from woofers - giving you better soundstage control. Your S320's front doors benefit most from components since you can mount tweeters at ear level. Rear deck or door positions work fine with quality coaxials. Save money on rears, invest in front components. Most people can't tell the difference from the back seat anyway.
What power rating should I look for in 6.5 inch S320 speakers?
Target 50-75 watts RMS for the 6.5 inch positions. Your factory Mercedes-Benz S320 amplifier likely pushes around 25-40 watts per channel. Higher-rated speakers won't get damaged by lower power - they'll just have more headroom. Peak power ratings are marketing nonsense. Focus on RMS. Sensitivity matters more than power handling anyway... speakers rated 90dB+ will sound louder than 85dB speakers even with the same amplifier.
Do 5.25 inch speakers in my S320 need different impedance than 6.5 inch ones?
Stick with 4-ohm speakers across all positions. Mercedes-Benz S320 factory systems expect 4-ohm loads. Using 8-ohm speakers cuts your power in half. 2-ohm speakers might overheat your amplifier. Mixed impedances create uneven volume levels between speakers. Keep it simple - 4 ohms everywhere. Your amplifier will thank you, and the sound balance stays consistent.
How do I verify my Mercedes-Benz S320 speaker sizes before buying replacements?
Measure the mounting holes, not the speaker cone. 6.5 inch speakers actually measure about 6.75 inches total diameter. Check mounting depth too - S320 door panels have limited clearance behind the grille. Remove one speaker first. Dashboard locations are particularly tight. Rear deck installations usually have more room. Don't trust online specs completely... actual fitment varies even within the same model range.
What frequency response should I target for S320 front door speakers?
Look for 45Hz-20kHz response in your front 6.5 inch speakers. The S320's cabin acoustics emphasize midrange frequencies around 1-3kHz. Bass below 50Hz gets handled by your door panels acting as enclosures anyway. Rear speakers can have narrower response since they're mainly for ambiance. Tweeters need clean extension to 15kHz minimum. Paper cones warm up the sound, but poly or aluminum might cut through road noise better.
