Mercedes-Benz CLS55 AMG Speaker FAQ

What speakers should I replace first in a Mercedes-Benz CLS55 AMG for the biggest sound improvement?

Replace the front door panel speakers first. The 6.5-inch front speakers handle most of your stereo imaging and vocal clarity. Since the CLS55 AMG uses either coaxial or component systems in front, upgrading these will give you the most noticeable difference. The rear door panels can wait - they're mainly for fill and ambiance. Focus your budget on quality front components around 75-100 watts RMS at 4 ohms. The rear 6.5-inch speakers will still contribute but the fronts do the heavy lifting for sound staging.

Can I install component speakers in all door locations of my Mercedes-Benz CLS55 AMG?

Yes, but it's probably overkill for the rears. Both front and rear door panels accept 6.5-inch coaxial or component speakers. The front doors benefit most from component separation since you're facing them directly. Rear components might improve sound quality slightly but... the improvement tends to be minimal compared to the extra cost and installation complexity. Most people run components up front and decent coaxials in back. Check if your Mercedes-Benz CLS55 AMG has factory tweeter locations in the rear doors first - that determines if components make sense back there.

What's the difference between coaxial and component speakers for my Mercedes-Benz CLS55 AMG door panels?

Coaxials combine the tweeter and woofer in one 6.5-inch unit. Component systems separate them - woofer goes in the door panel, tweeter mounts elsewhere, usually in the sail panel or dash. Components generally sound better because the tweeter can be positioned at ear level for better imaging. The crossover network is external too, which helps frequency separation. Coaxials are easier to install and cheaper. For the CLS55 AMG, components make the biggest difference up front where stereo imaging matters most. Expect to pay 2-3x more for decent components versus coaxials though.

Will 6.5-inch aftermarket speakers fit properly in my Mercedes-Benz CLS55 AMG door panels?

Most 6.5-inch speakers should fit the mounting holes fine. The depth might be your main concern - measure the space behind the factory speaker first. Standard aftermarket speakers are usually around 2.5-3 inches deep. Some high-performance speakers can be deeper than 3.5 inches which could interfere with the window mechanism. Also check the mounting tabs - Mercedes sometimes uses proprietary spacing. You might need speaker adapters or brackets. The good news is that both front and rear door panels in the CLS55 AMG use the same 6.5-inch size, so you can standardize on one speaker model if you want.
