Buy affordable 8 inch subwoofer enclosures online at the Carhifi online shop Masori

If you want to equip your car with a powerful bass upgrade, Masori offers a wide range of 8-inch subwoofer enclosures, often also referred to as 20cm subwoofer boxes or Carhifi bass boxes. Whether you want to optimize your Carhifi system for music genres like hip-hop, rock, or electronic sounds – our enclosure solutions meet the highest demands for sound pressure and bass quality. Thanks to their compact dimensions, these subwoofer enclosures can be flexibly installed both in the trunk of small VW models and in large BMW or Mercedes sedans. Especially for sound fans of Opel or SEAT, there are also plug & play options available that can be quickly integrated.

Car Audio Highlights and Key Figures

An 8" subwoofer enclosure typically offers the following technical specifications:

• RMS power from 200 watts to 300 watts
• Frequency range between 35 Hz and 500 Hz
• Impedance of 4 ohms for efficient power transfer
• Sound pressure level up to 95 dB for powerful bass
• MDF enclosure construction for reduced enclosure volume with high stability

These key figures allow for deep bass reproduction without distortion. Whether you want to fill your car interior with crisp bass or enjoy the full frequency spectrum in crystal-clear form – thanks to different designs such as sealed or bass reflex, every sound goal can be achieved.

Overview of different designs and their effects

Whether you choose a sealed subwoofer enclosure or prefer a bass reflex design depends on whether you want more powerful low frequencies or exact bass control. The available space in the car and the power of your car audio amplifier also play a role.

Manufacturers and brands in the portfolio

Our 8" subwoofer boxes come from established manufacturers such as Audio System and dBvox, as well as our own Masori developments. Audio System is known for sophisticated designs with high power handling, which have also proven themselves in BMW or Audi vehicles. dBvox stands out with solid MDF enclosures and top-quality workmanship details. Masori also offers innovative solutions for particularly tight installation spaces and plug & play compatible concepts. All variants have been extensively tested to ensure precise car audio tuning without compromise.

Installation in various vehicles

The compact diameter of 20 cm allows use in many vehicle types:

• VW Golf or Polo: Trunk integration with minimal space requirement
• BMW 3 Series or 5 Series: Rear shelf or trunk corner for powerful bass impulses
• Mercedes C-Class or E-Class: Smooth integration under rear seats or in side areas
• Opel Astra or Corsa: Perfect for compact vehicles with limited space
• SEAT Leon: Premium bass tuning even in sporty hatchbacks
• Audi A4 or A3: Intense low end with good frequency response over standard amplifiers

If you have questions about installation, our Expert Support. Alternatively, the team at Masori can be reached via the AI chatbot consultation can check possible compatibilities with your vehicle. If you don't have the time or experience for installation yourself, our Installation Service in Frankfurt Oder is available.

Installation tips and useful accessories

A cleanly executed installation is crucial so that your car sound is not only loud but also precise. Our accessory range offers:

• High-quality car audio amplifiers with Class-D technology for efficient power amplification
• Matching crossovers to relieve midrange and tweeters
• High-quality OFC cable sets (Oxygen Free Copper) for stable voltage and signal transmission
• Professional damping materials to minimize vibrations and resonances
• Plug & Play kit solutions for vehicles with factory-installed sound systems

When positioning the 8" subwoofer, secure mounting is important to reduce vibrations. A stable MDF enclosure with reinforced corners or angles ensures that the sound pressure is directed into the vehicle interior – without rattling noises.

Technical specifications in detail

Focusing on maximum performance values and low distortion, 8-inch enclosures meet numerous requirements:

• Maximum power handling: Up to 300 watts RMS, suitable for powerful mono amplifiers
• Sensitivity: Values between 85 dB and 95 dB for sufficient level with smaller amplifiers
• Internal volume: Optimized for linear reproduction in sealed systems or for more punch in bass reflex variants
• Material thickness: 15 mm to 22 mm MDF panels for stable construction without unwanted resonances

The result is a consistent, powerful low-end sound that can be combined with any music style. Especially for bass-intensive tracks, the appropriate design ensures undistorted deep bass foundations.

Integration into existing car audio systems

If you have already installed speakers in the doors or dashboard (front systems), it is recommended to use precise frequency separation via a crossover or active DSP (Digital Sound Processor). An 8" subwoofer handles the bass frequencies up to around 120 Hz, while midrange and tweeters cover the higher ranges. Such a division relieves the overall system and significantly enhances the acoustic impression. In the Masori online shop, you will find suitable system amplifiers that offer multiple channels and an adjustment interface. This allows you to optimally distribute the power, whether you are installing a basic system in a VW Polo or a high-end audio set in a Mercedes sedan.

Maintenance and durability

To enjoy your car audio bass box for years, you should occasionally clean the subwoofer enclosure from dust and dirt. Also pay attention to the following points:

• Regularly tighten loose screws to avoid sound loss
• Check seals and connection terminals to prevent dropouts
• Check cable connections for secure fit, especially after workshop-related modifications in the trunk
• Avoid temperature fluctuations to keep wood and glue joints intact

If damage occurs, our Installation Service in Frankfurt Oder is always at your disposal. There, not only replacement parts can be installed, but also upgrades such as more powerful subwoofers or additional damping can be realized.

Versatile connection options and signal processing

For ideal interaction with your amplifier, the correct impedance choice is essential. Almost all 8" models in our range use 4 ohms, which is the most common variant for mono and multichannel amplifiers. It is also advisable to carefully adjust the gain settings on the amp to prevent clipping. Using a separate low-pass filter, the subwoofer receives only the frequencies relevant for bass. Combined with good interior damping, you achieve a crisp, uncolored bass – whether you listen to metal, charts, or drum and bass.

Your path to rich bass in everyday life

8 inch subwoofer enclosures are the ideal choice for music lovers who want a noticeable bass kick without taking up the entire trunk. Combined with the right Carhifi components, you get a wide frequency spectrum. Thanks to our large selection of bass enclosures and the supporting services at Masori, you can optimize your Carhifi system step by step.
