Those who want to upgrade their car audio system with rich-sounding car hi-fi components will find a first-class selection at SoundQubed. Whether powerful subwoofers for sealed enclosures, durable speakers for clarity across all frequency ranges, or full-bridge amplifiers with high power reserves: with over 20 years of experience in the car hi-fi world, the company offers versatile solutions for a wide range of sound projects. Many music fans rely on the famous HDX subwoofers with large Xmax and the HDS series for SQ applications. Thanks to enormous RMS values and robust voice coils, they produce deep bass without losing precision.

On site in Frankfurt Oder Installation services are available to optimally integrate the new audio system.
Subwoofer Technologies and Installation Instructions
SoundQubed offers several product lines with sophisticated technical specifications. The HDX series is among the SPL specialists. With an Xmax of up to 25 mm, voice coil diameters up to 3 inches, and a low-resonance diaphragm design, they deliver powerful bass in the range between 20 Hz and 300 Hz. For detail-oriented sound enthusiasts, the HDS series is recommended. It scores with:
- Frequency range from approximately 25 Hz to 250 Hz
- RMS power from 750 to 1,000 watts
- Enclosure compatibility for sealed applications or bass reflex variants
- Air-cooled pole plates for reduced distortions
- Improved connection to woofers and centering spiders
Those planning a quick installation in the BMW 3 Series (E90) or VW Golf 7 can often rely on plug-and-play adapters. Additionally, damping materials for door panels and the trunk are recommended to minimize resonances. Necessary accessories such as RCA cables, power cables, capacitors, and suitable fuse holders for high currents are essential for the subwoofers to deliver their full performance.

Speaker options for maximum sound quality
In addition to subwoofers, SoundQubed offers a portfolio of coaxial and component speakers for car audio enthusiasts who value clear mid-high frequency reproduction. Typical features include:
- Frequency responses up to 20 kHz
- Sensitivity over 87 dB
- Light membrane materials such as polypropylene or woven fiberglass
- High durability thanks to stable pole core ventilation
For Audi A4, Mercedes C-Class, or Seat Leon drivers, custom installation adapter rings are often available to securely and vibration-free mount the new car audio speakers in the vehicle. To avoid rattling, aluminum butyl and alternative damping materials are recommended to further optimize the sound character.
Efficient amplifier solutions and accessories
The utility amplifiers from SoundQubed provide a practical full-bridge solution for power-hungry setups. They impress with:
- Class-D technology for minimizing waste heat
- Output power from 1,000 to over 3,000 watts RMS
- High efficiencies of over 80 %
- Variable low-pass filter (LPF) from 40 Hz to 300 Hz
- Multistage protection circuits (short circuit, overheating, undervoltage)
Thanks to full bridge boards, these amplifiers can also operate stably at low impedances. For Opel Astra or VW drivers planning a more comprehensive car hi-fi sound upgrade, a well-dimensioned power cable set (at least 25 mm² cross-section) including cable management is also recommended. A capacitor or an additional onboard battery ensures constant power supply and prevents voltage drops during heavy bass attacks.
