Mercedes-Benz 280E Speaker FAQ

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

Replace the 5.25 inch rear deck speakers first. They handle most of your bass and midrange output - around 80% of what you actually hear. The dashboard 4 inch speakers mostly fill in treble gaps. Your 280E's rear deck location gives better acoustic coupling with the cabin space, so upgrades there deliver more noticeable improvement per dollar spent.

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

Yes, the rear deck accepts component systems. You'll need to mount the tweeter separately - either in the rear parcel shelf or aim them forward toward the seats. The woofer drops into the existing 5.25 inch opening. Component separation typically improves imaging, though the rear-firing position in your 280E might limit the stereo effect. Coaxial speakers often work better for rear fill applications.

What power handling should I look for in 280E replacement speakers?

Target 40-60 watts RMS for the rear 5.25 inch position, 25-35 watts for the dashboard 4 inch speakers. Most aftermarket head units push 15-20 watts per channel, so don't worry about matching peak power ratings. The Mercedes-Benz 280E's interior acoustics are fairly dead - you need efficient speakers rather than high power handling. Look for sensitivity ratings around 88-91 dB for noticeable volume improvements.

Will full-range speakers work better than coaxials in my 280E?

Full-range drivers can work, but they limit your frequency response. The 4 inch dashboard position particularly struggles with bass below 150 Hz anyway. For the rear deck, coaxials give you dedicated tweeters that help with detail and clarity. Your Mercedes-Benz 280E benefits from the tweeter separation since the rear-firing position can muddy high frequencies. Full-range might sound more natural in the mids though.

What impedance speakers does the Mercedes-Benz 280E use?

Standard 4-ohm speakers work fine. The factory system expects this impedance, and most aftermarket head units handle 4-ohm loads without issues. Some people try 8-ohm speakers thinking they're "better" - they're not necessarily. Lower impedance actually draws more current, which can mean slightly better damping factor. Your 280E's electrical system handles the current draw from 4-ohm speakers without problems.
