Buy Cheap: Cap in the Carhifi Online Shop Masori
Whoever is looking for powerful caps for an enhanced car sound experience will find a variety of audio capacitors in the Masori car audio online shop. Whether for plug & play solutions in BMW, Audi, VW, Mercedes, SEAT, or Opel – high-quality cap variants from renowned manufacturers like B2 Audio and DD Audio ensure optimal energy buffering. With precise capacitance values from 1µF up to several hundred microfarads, a voltage rating of up to 400 volts, and low impedance, these components are designed for demanding audio applications in vehicles. They filter frequencies, stabilize the DC power supply, and optimize sound in every car audio system thanks to low equivalent series resistance.
Diverse car audio solutions with caps
In addition to classic film capacitors and electrolytic capacitors, the online shop also offers tantalum capacitors for enormous durability. B2 Audio Caps provide extended application possibilities to achieve deep bass frequencies and clear highs. DD Audio Caps impress with higher voltage reserves, which is particularly interesting for power-intensive car sound systems with multiple amplifiers. Many models have been specially developed for complex crossover and speaker configurations to direct low frequencies to subwoofers and high frequencies to tweeters.
Suitable for plug & play connection to original VW or Opel sound amplifiers, audio capacitors can be integrated variably without complex modifications. Forum reports and technical documentation confirm that caps like the high-performance capacitors from B2 Audio precisely filter a frequency range down to the lower Hertz range, thus avoiding dips in the midrange segment. In addition, they score with:
- High-quality dielectric for maximum voltage resistance
- Low ESR (Equivalent Series Resistance) to minimize signal loss
- Precise capacity tolerance for optimal crossover frequencies
- Compact designs for flexible installation options in any car
Manufacturer selection and specifications
When choosing the right cap, it is important to precisely match capacity, impedance, and voltage rating. B2 Audio focuses on innovative designs and withstands resistances in the range of a few milliohms, resulting in minimal energy loss. DD Audio, on the other hand, relies on robust housings for damage-free operation at high RMS power levels in car audio amplifiers. Technical highlights include:
- Capacity values: 1µF up to several hundred microfarads
- Voltage ranges: 50 V to 400 V
- Tolerance levels: ±5% to ±10%
- Designs: Cylindrical, radial, or axial
- Connection options: crimp connectors, solder tabs, screw terminals
Those who rely on bass can adjust the frequency response for subwoofers with higher capacities, such as 100µF. For precise high-frequency filtering, a cap with 2µF to 10µF is ideal. This creates optimal sound throughout the entire car audio system, whether for a SEAT Ibiza or a Mercedes C-Class.
Integration options for your car
The flexible integration of the caps into existing car audio systems is the focus: Numerous B2 Audio models can be connected to existing car sound amplifiers with just a few simple steps using RCA cables and cable adapters. Thanks to suitable cable cross-sections (for example, 2.5 mm² to 16 mm² depending on power), the efficiency of energy transmission is increased. Particularly recommended are:
- Plug-in mounting systems for quick commissioning
- Protective case for stresses in the trunk
- Insulating materials to reduce electrical interference
- Soldering kits in professional quality for permanently stable contacts
Optimized signal transmission and frequency filtering
The characteristics of a capacitor greatly influence the signal quality. Caps with low impedance complement powerful car amps in BMW or Audi models, which often have to handle high peak currents. With the right electrolytic capacitor, the DC voltage at the amplifier can be reliably absorbed, so that no clipping or distortion effects affect the sound. Additionally, film capacitors reduce high-frequency interference, which is especially relevant for amplifiers with Class-D technology.

Professional installation tips and accessories
For flawless operation, a clean installation is crucial. Suitable locations are often close to the amplifier or the crossovers to keep losses low. Stable screw terminals help avoid interference and make retrofitting easy. Those with perfectionist car audio demands also pay attention to:
- Installation of signal cables separate from power lines
- Secure mass screw points for the cap housing
- Mounts with vibration protection in the footwell or trunk
- Sufficient cable cross-section (depending on RMS output power)
Should the installation become too complex, our installation service in Frankfurt Oder will be happy to assist you (Installation on site), who takes care of all the details and selects the optimal capacity for your car. This way, car audio projects can be precisely implemented in any Mercedes, Opel, or SEAT.

Performance parameters, impedance, and practical added value
A cap with high capacity (e.g., 470µF to 1000µF) stabilizes the power supply in active car audio systems and ensures consistent levels during transient peaks. Especially in Class-D amplifiers, which attract short pulse peaks, a proper capacitor prevents noticeable sound loss. Additionally, a low impedance reduces noise and allows clean transitions between treble, midrange, and bass. B2 Audio caps with 2.5µF or 4.7µF shine as treble filters in brilliant Hi-Res audio recordings, while DD Audio models in intermediate ranges up to 100µF provide balanced midrange.
Those who rely on tried-and-tested kits for car audio tuning benefit from an optimal interplay between amplifier, crossovers, and caps. Perfect for dynamic sound systems, as often retrofitted in sporty SEAT Leon or Golf GTI models. In addition to technical performance, these audio capacitors provide an audible added value by preventing level fluctuations during power-hungry passages and ensuring a consistent soundscape in the long term.
