Mercedes-Benz E400 Speaker FAQ

Should I replace front door speakers first in my Mercedes-Benz E400?

Replace the front door 6.5 inch speakers first. They handle most vocal frequencies and midrange content where you'll notice the biggest improvement. The front tweeters can wait - they're already positioned well in the E400's door panels. Focus your budget on quality 6.5 inch components with separate crossovers, around 75-100 watts RMS. You spend most listening time with front stage anyway.

What's the difference between coaxial and component speakers for E400 doors?

Component speakers separate the tweeter from the woofer - better imaging since each driver handles its optimal frequency range. Coaxials put everything in one unit, easier install but compromised sound staging. The E400 already has dedicated tweeter locations, so components make sense. Run 4-ohm components at roughly 80 watts RMS. The factory crossover points might need adjustment though.

Can I use full-range speakers in Mercedes-Benz E400 rear doors?

Full-range speakers work but they're trying to do everything - bass, mids, highs. Not ideal when your E400 has separate tweeter positions. Better to stick with dedicated 6.5 inch woofers for rear doors, let the rear tweeters handle the top end. Frequency response stays cleaner this way. Aim for speakers that roll off naturally around 3-4 kHz.

Are 2.75 inch rear deck speakers worth upgrading in E400?

Those tiny rear deck speakers mostly fill in ambient sound. Low priority upgrade since they can't produce meaningful bass below 200 Hz anyway. If you do replace them, look for speakers with good efficiency - maybe 88-90 dB sensitivity. The mounting space is tight in the E400 rear deck. Small coaxials might give you slightly better highs than full-range drivers.

How many speakers does the Mercedes-Benz E400 actually need?

The E400 setup suggests a multi-driver approach - front components with separate tweeters, rear fill speakers. You could simplify to just front 6.5 inch components and skip the rear entirely. Depends on whether you want surround effect or focused front staging. The rear side panel tweeters mainly create ambiance for back seat passengers.

What impedance should I use for E400 speaker replacements?

Stick with 4-ohm speakers. Mercedes factory amplifiers typically expect this load. 8-ohm speakers might sound quieter, 2-ohm could stress the amp. The E400's electrical system should handle 4-ohm loads fine across all positions. Check your amplifier specs first though - some aftermarket amps prefer different impedances.
