The MATCH UP W8BMW-S is a pair of ultra-flat 8-inch 2 ohm upgrade subwoofers that fit the original under-seat mounting positions of all BMW model ranges with under-seat subwoofers, including the 1, 2, 3, 4, 5 and X Series. It is for BMW owners who want more powerful bass from a direct replacement for the original subwoofers of the BMW HiFi sound system.

MATCH UP W8BMW-S 2 ohm

Approved compatibility with BMW models

Premium cars deserve premium sound. In many cases the basic speaker setup in BMW vehicles does not meet the expectations of ambitious music lovers.

MATCH UP W8BMW-S: maximum power for BMW sound concepts

The ultra-flat UP W8BMW-S subwoofers play extremely dynamically and punchily. The exceptionally rigid fibreglass cone generates maximum sound pressure without distortion.

The BMW-specific baskets and connectors allow fast and easy installation into the original mounting positions of all BMW model ranges with under-seat subwoofers.

These subwoofers are also well suited to universal applications. Thanks to the very low mounting depth, extremely compact sealed enclosures are no problem at all, while the oversized 1.7" / 42.5 mm voice coil assures high power handling.

With their 1 x 2 ohm single voice coil, the UP W8BMW-S are the perfect replacement for the original subwoofers of the BMW HiFi sound system. They are also the perfect partner for the MATCH Upgrade amplifiers MATCH UP 7BMW and MATCH UP 7DSP.

Whether these subwoofers are used for a bass upgrade in your BMW or to supply low frequencies in universal concepts, they will add plenty of powerful bass for musical enjoyment.

About the Match M130802

From our tech experts at CEN

A Match compact subwoofer, 8 inch, designed to fit where a conventional sub cannot.

Who it suits

Drivers who want low end in a vehicle with no usable boot space, and factory-system upgrades where the sub has to hide under a seat or behind trim.

Our tech experts advise

Compact subwoofers depend heavily on placement and on being set up against the front speakers, otherwise they sound detached from the rest of the system. 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 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.
