Spare wheel subwoofer box deep bass without losing your trunk space

Want to add real bass to your car without installing a large subwoofer in the trunk? Discover our spare wheel well subwoofers: compact and discreet solutions designed to make use of the space under the trunk floor.

SPARE WHEEL SUBWOOFER

Keep your trunk, add the bass

The spare wheel subwoofer box is an ideal solution for drivers who want to significantly improve the bass in their audio system while preserving the cargo space.

Installed in or around the spare wheel well, the subwoofer remains under the trunk floor depending on the vehicle configuration and the chosen model.

Preserved trunk space Keep your usable space
Discreet installation Under the trunk floor
Active or passive Depending on your setup
Real bass Enhance your audio system
WHY IS IT SO POPULAR?

The subwoofer you hear without necessarily seeing

You no longer need to choose between bass and the available space in your trunk. The spare wheel subwoofer box uses an area that is usually underutilized to house the subwoofer.

Groceries & luggage The trunk remains available for everyday use.
Discreet installation The equipment can remain hidden under the floor.
Improved sound Add the bass that is missing from the original system.
ACTIVE OR PASSIVE

Which spare wheel subwoofer box should you choose?

Our range mainly includes powered subwoofers, but also passive solutions that allow you to use an external amplifier.

Spare wheel subwoofer powered

The active subwoofer box has its amplifier built in. It is a particularly convenient solution for adding a subwoofer to an existing setup without having to install a separate bass amplifier.

Spare wheel subwoofer passive

The passive model does not have built-in amplification. It must be paired with an amplifier compatible with its RMS power and impedance.

ORIGINAL CAR STEREO • OEM

Improve the bass without necessarily changing your car stereo

A powered spare wheel subwoofer box can be integrated into many original audio systems. Some models offer high-level inputs that allow you to pick up the signal from the speakers.

Depending on the vehicle and the product chosen, a high-level input, an HP to RCA converter, or a specific interface may be necessary.

SAVE SPACE

An alternative to a large subwoofer in the trunk

Traditional subwoofers can take up a large part of the cargo volume. The spare wheel subwoofer box meets a different need: to get more bass with a much more discreet integration.

Installation under the floor

Depending on the vehicle and the model, the subwoofer can fit in the spare wheel area and remain under the trunk floor.

Low height

Several models are specifically designed with a reduced height to make it easier to fit them into the spaces available under the trunk.

Discreet mounting

Once properly integrated, the system can become practically invisible when the trunk floor is put back in place.

Everyday use

A particularly interesting solution for a car used every day when you want to keep the trunk for groceries, luggage, or equipment.

SEVERAL FORMATS AVAILABLE

From ultra-flat subwoofers to circular models

Not all spare wheel subwoofers use the same design. Some models are circular and can fit in a rim or a suitable housing, while others use a flat box designed to fit in the area under the floor.

The choice therefore depends above all on the shape and dimensions available in your vehicle.

Measure your space before ordering.

There is no universal dimension for all vehicles. Check the diameter, width, length, and especially the height available under the floor. Also check if you want to physically keep the spare wheel: compatibility depends on the design of the subwoofer box and the available space.

BUYER'S GUIDE

How to choose your spare wheel subwoofer box?

A few simple checks can help you avoid a compatibility error and choose the model that is really suitable for your vehicle.

✓ Diameter — measure the available housing
✓ Height — check the space under the floor
✓ Type — active or passive subwoofer box
✓ Signal — RCA or high-level depending on the model
✓ Power — compare the RMS values
✓ Spare wheel — check if it can be kept
SPARE WHEEL ACTIVE SUBWOOFER BOX

The simplest solution for a complete installation

The majority of references in this category have built-in amplification. You thus choose a set where the subwoofer and its amplification are already paired.

Built-in amplifier

No need to plan for a separate mono amplifier. The amplification module is directly built into the bass system.

Accessible settings

Depending on the model, you can find different settings such as level, low-pass filter, phase, or even a remote control.

GROUND ZERO • MUSWAY • ESX • HIFONICS

Specialized solutions for the spare wheel well

Sound Auto Concept offers different spare wheel subwoofers from brands specializing in Car Audio such as Ground Zero Audio, Musway, ESX Car Audio, and Hifonics.

The range allows you to choose between several dimensions, power levels, and designs to adapt the installation to the available space and the desired level of bass.

Do not choose solely the model displaying the most Watts.

In this category, the priority is often the compromise between size, integration, and bass reproduction. RMS power is important, but the speaker diameter, the design of the subwoofer box, its efficiency, its location and the settings also influence the final result.

FOR WHICH USER?

The ideal choice if you want bass without sacrificing the trunk

Family car Keep the trunk available for luggage.
Everyday vehicle Enjoy better bass without a bulky installation.
Discreet installation A Car Audio solution designed to remain barely visible.
