About the Focal ISUB MBZ 2 RHD
From our tech experts at CEN
A direct-fit Focal subwoofer for the Mercedes, designed for the factory footwell location so it adds bass without losing boot space.
Who it suits
Mercedes owners who find the factory system short of low end, and anyone who wants the upgrade to sit as though it came from the factory.
Our tech experts advise
Fitment depends on model, year and factory audio specification, so we confirm before ordering. It still wants amplification and setting up against the front stage so it blends rather than thumps. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions
Q: Do I need an amplifier for this subwoofer?
A: Yes, unless it is an active (powered) subwoofer with a built-in amplifier. Passive subwoofers need an external amplifier matched to the RMS power and impedance shown in the Specification tab.
Q: What does RMS power mean?
A: RMS is the continuous power a subwoofer can handle, and it is the number that matters when matching an amplifier. Peak or max figures describe short bursts only. Match your amplifier output to the RMS rating in the Specification tab.
Q: Can CEN build or supply an enclosure and fit everything?
A: Yes. CEN supplies enclosures and offers professional installation from our Nottingham premises, including amplifier wiring. Contact us to discuss your build.
Q: Will the ISUB MBZ 2 RHD fit a left-hand drive Mercedes?
A: No. This version is for right-hand drive vehicles only.
Q: Which Mercedes models does the ISUB MBZ 2 RHD fit?
A: It is designed for the Mercedes-Benz C-Class, E-Class, S-Class and GLC in right-hand drive. Contact CEN with your registration to confirm your vehicle.
Q: Is the ISUB MBZ 2 RHD a pair?
A: Yes. It is a pair of dedicated left and right 8 inch subwoofers, each handling 75W RMS at 2 ohms.
