The Match UP W8BMW-S is a pair of 8-inch, 2-ohm underseat subwoofers designed as direct replacements for the original subwoofers in BMW HiFi-equipped 1, 2, 3, 4, 5 and X Series models. Rated at 200 W RMS / 400 W max per pair, they are part of the Match Upgrade (UP) range of BMW-specific audio upgrades.
This listing is the 2-ohm version. The UP W8BMW is also available in 4-ohm (UP W8BMW-D).

Approved compatibility with BMW models
The UP W8BMW-S fits directly into the original under-seat mounting positions of all BMW model ranges equipped with under-seat subwoofers, including the 1, 2, 3, 4, 5 and X Series. BMW-specific baskets and connection cables are included for fast installation into the original cable harness.
Maximum power for BMW sound concepts
The ultra-flat UP W8BMW-S subwoofers deliver dynamic, punchy bass. The rigid fibreglass cone generates maximum sound pressure without distortion, while the oversized 42.5 mm (1.7") voice coil handles high power with ease.
With a 1 x 2-ohm single voice coil, the UP W8BMW-S is the correct impedance match for the original BMW HiFi system and pairs directly with the Match UP 7BMW plug-and-play amplifier and DSP.
The 40 mm mounting depth also makes these subwoofers suitable for universal use in ultra-compact sealed enclosures outside of BMW applications.

About the Match M130802
From our tech experts at CEN
The Match UP W8BMW-S is a pair of 8-inch, 2-ohm underseat subwoofers built as direct replacements for the original bass drivers in BMW HiFi-equipped 1, 2, 3, 4, 5 and X Series models. Rated at 200 W RMS and 400 W max per pair, they feature a stiff fibreglass cone and an oversized 42.5 mm voice coil. BMW-specific connection cables for the original harness are included in the box.
Who it suits
These suit BMW owners who want noticeably better bass without altering factory mounting positions or wiring. The 2-ohm impedance matches the original BMW HiFi system directly. If your amplifier requires a 4-ohm load, consider the Match UP W8BMW-D instead.
Our tech experts advise
Confirm your BMW is fitted with factory under-seat subwoofers before ordering, as not all variants include them. For best results, pair with the Match UP 7BMW plug-and-play amplifier and DSP. The 40 mm mounting depth also makes these suitable for ultra-compact sealed enclosures outside BMW applications. Installation is priced per vehicle — visit our Nottingham fitting page for details.

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 size enclosure does this subwoofer need?
A: The recommended enclosure volume is listed in the Specification tab where the manufacturer provides it. As a rule, sealed enclosures give tighter, more accurate bass while ported enclosures deliver more output. Contact CEN if you would like a recommendation for your build.
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: Sealed or ported enclosure - which should I choose?
A: Sealed boxes are compact and produce tight, controlled bass suited to sound quality builds. Ported boxes are larger and produce more output at low frequencies, suited to those who want maximum impact. Either works well when built to the recommended volume.
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 MATCH UP W8BMW-S fit my BMW?
A: They are designed for all BMW model ranges with under-seat subwoofers, fitting the original mounting positions under the front seats using BMW-specific baskets and the included BMW connection cables. Contact CEN with your model and year if you are unsure whether your car has under-seat subwoofers.
Q: Are the W8BMW-S sold as a pair?
A: Yes. The box contains 2 x MATCH UP W8BMW-S subwoofers, 2 x BMW connection cables, mounting material and an instruction manual.
Q: Which amplifier works best with the W8BMW-S subwoofers?
A: With a 1 x 2 ohm single voice coil they directly replace the original subwoofers of the BMW HiFi sound system, and they are designed to pair with the MATCH UP 7BMW and MATCH UP 7DSP upgrade amplifiers.
