Please note, this kit is also available with an optional full speaker option (see our website for "Soundstage Speaker Kit"). The full speaker kit includes a custom engineered set of front speakers, dedicated amp and all required parts to take your stock system to the next level. Contact us for more details!!

See drop down menu for option to add the optional amplifier.

Lets face it, the stock and Harman Kardon stereos are not worth the money. Upgrading to the HK system is similar to taking a $1,500.00 chunk of $100's and tossing it in the trash. You may get a LITTLE bit more definition in the mids (usually from 3"-6" speakers) and highs (tweeters, etc) but still the bass bites it big time (slang for being crappy) and for what you pay you should at least get a 8" sub or a set of 6x9's that are in a sealed enclosure...but you don't. While they market it pretty heavily and have a nice "Harman Kardon" badge. etc, don't believe the hype.

While this sub box will not improve on the mids and highs, it will compliment it and offset the weak links in the system. Basically this is as turn key as it gets when it comes to adding bass emphasis into the MINI Cooper stereo system. Sure, you can get a Bazooka tube or a nasty looking 'sub-in-a-box' from your local Best Buy or whatever but there is a slim chance it will even come close to quality of the bass from this custom bass enclosure. This unit was developed and refined by what I consider to be one of the most knowledgeable people in the MINI audio world and after talking with the owner at length I decided we had to offer this to our customers. While it will require some work to install it, the benefits are well worth it.

By making a 'false floor' they were able to hide a very nice 10" sub as well as a dedicated amp to power it, which in turn keeps a majority of already small trunk space usable.

Integral Audio took the best subwoofer system the MINI Cooper has ever seen - the Model 1100 - and made it even better. The new & improved Model 1101S Subwoofer System for the MINI adds a dash-mounted remote level control, simplified signal wiring wiring, secure easy connections with Positaps™, and improved mounting hardware.

Nearly 1/3 of music is below 100Hz.  Your car’s small factory speakers can’t move enough air to produce those frequencies.  If you want to start hearing ALL of your music – the way it was meant to be heard - you need a subwoofer.  And if you want a subwoofer that looks like it came with the car when you bought it, you need an Integral Audio Subwoofer.  The FactoryFit™ Subwoofer Systems add an amazing balance and richness to your music without taking anything away from your vehicle’s interior.

The MINI Cooper Model 1101S Subwoofer System is capable of delivering loads of chest pounding bass, but what it’s really designed for is accuracy – every note, every nuance.  Isn’t it time to hear what you’ve been missing?

What's Included:

Model 1101S Phantom™ Subwoofer Enclosure & Cover Panel
10" Audiophile Subwoofer by SBAcoustics
Custom Mounting Brackets & Hardware
Amplifier by ARC Audio, Class-H delivering 250W [optional]
Amp Mounting Bracket & Hardware [optional]

The Model 1101S is a complete system including the enclosure, subwoofer, amplifier, and ALL necessary wiring and hardware! It installs in the boot and offers a clean, professional installation with the boot remaining completely usable. The enclosure can be removed in less than 30 seconds if the extra storage space is needed or for reducing weight for the track. Less than 1 cubic foot of boot space is lost, and the entire system weighs a mere 29 lbs! The installation of the Model 1100S requires NO cutting of wires and is appropriate for leased vehicles.
Clean, musical, authoritative bass is delivered by the new Integral Audio IASW26-4 10" subwoofer designed by SBAcoustics. The IASW26-4 is powered by the legendary Robert Zeff-designed ARC Audio KS125.2 MINI. The lightweight enclosure cabinet features extensive internal bracing and custom mounting hardware. The completely stealth look is acheived with a false floor panel with a heavy-guage steel grill that is completely covered with acoustically-transparent carpet that matches your MINI's interior. The false floor is designed to create a level load floor in the boot with seats folded down and allows the subwoofer to operate normally even if the boot is FULLY LOADED!
The Model 1101S has been carefully engineered as a complete system specifically for the MINI, with each component carefully designed with the other components and the vehicle in mind. You can't achieve this level of sound quality otherwise - the flat frequency response and clean transients of the 1101S simply can't be replicated with off the shelf products.

Please see drop down menu for model selection. These are made specific to each MINI model.
