Mercedes-Benz 280C Speaker FAQ

What speakers should I replace first in my Mercedes-Benz 280C?

Replace the 5.25 inch rear deck speakers first. They handle most of your music's foundation - the midrange frequencies where vocals live. The dashboard 4 inch speakers mainly fill in treble, so they're secondary. Your 280C's rear deck location typically gets better power delivery too, around 20-30 watts RMS versus maybe 15 watts to the dash. Start there and you'll notice the biggest improvement.

Can I install component speakers in the Mercedes-Benz 280C rear deck?

Yes, but it's probably overkill. The rear deck supports components, coaxials, or full-range speakers. Component systems separate the tweeter from the woofer - great for staging but complex in a 280C. Most people get better results with quality coaxials back there. Save components for front locations where imaging matters more. Unless you're building a serious system, coaxials will give you 80% of the performance with half the work.

What's the power handling difference between locations in a Mercedes-Benz 280C?

The rear deck 5.25 inch speakers can handle more power - typically 25-40 watts RMS depending on your setup. Dashboard 4 inch speakers are more limited, maybe 15-25 watts RMS max. The size difference means the rear speakers move more air, handle bass better. Don't overpower the dash speakers thinking more watts equals better sound. They're designed for midrange and treble fill, not heavy lifting.

Should I use full-range speakers in my Mercedes-Benz 280C?

Full-range speakers work fine in both locations, especially if you're keeping the system simple. They try to cover 80Hz to 20kHz in one driver - decent for most music. The 5.25 inch rear deck full-range speakers will sound fuller than the 4 inch dashboard ones. But if you want clarity, coaxials separate the tweeter which usually sounds cleaner. Full-range is easier to install though. No crossover networks to worry about.

What impedance should I use for Mercedes-Benz 280C speakers?

Stick with 4-ohm speakers for both locations. Your 280C's factory system expects around 4 ohms, and most aftermarket head units prefer this too. 8-ohm speakers will play quieter, 2-ohm might stress your amplifier. The dash and rear deck can both run 4-ohm speakers without issues. Don't mix impedances - if you go 4-ohm in the rear, use 4-ohm up front too. Keeps the load balanced.
