Buy 50mm² Power Cable Cheap Online at the Masori Car Audio Online Shop
With a large-dimensioned 50mm² power cable in the car, powerful car audio systems can be operated particularly efficiently. An optimal cross-section like 50mm² noticeably reduces voltage losses and ensures a consistent supply to amplifiers, subwoofers, and speakers. Car audio enthusiasts can get such large-format cables from Masori in various lengths and versions for VW, Audi, BMW, SEAT, Mercedes, and Opel – of course in top quality. Below, we show why a 50mm² cable is especially worthwhile, what differences exist between the brands, and how the accessories can ideally complement each other.
Technical details and areas of application in car audio
A 50mm² power cable for car audio applications operates with a very high current carrying capacity. Typically, up to 300 amperes can be transmitted with an impedance of less than 0.1 ohms. This ensures that the supply voltage remains stable even with powerful amplifiers. The conductor material used is at least OFC copper (Oxygen Free Copper) or high-quality 99.9% copper. The outer insulation is often made with thick PVC sheathing or TPE cable material, which also provides resistant protection against extreme temperatures and vibrations.
- Nominal cross-section: 50mm²
- Maximum current: up to 300A
- Typical conductivity: ≤0.1 ohm on cable length-related measuring section
- Insulation material: PVC or TPE
- Recommended vehicle categories: Audio upgrades with multiple amplifiers
Important Criteria for Selection
Anyone choosing a 50mm² power cable for their car audio system should pay particular attention to the conductor material content, flexibility, and shielding quality. Audio systems in vehicles benefit from dense insulation because it effectively keeps electromagnetic interference signals at bay. Additionally, highly flexible cables make installation easier as they adapt optimally to the interior and can be laid without kinking.

Audio System 50mm²: Solder Stop and Minimization of Interference
Audio System 50mm² cables feature additional shielding and solder stop technology at the ends, which reduces cable-side contact resistance. This prevents voltage losses, especially in very long installation runs.
Deaf Bonce 50mm²: Fence against extreme conditions
Deaf Bonce relies on double insulation that protects the cable even under adverse weather conditions. Suitable for vehicles exposed to extreme temperature ranges or experiencing heavy vibrations, for example on unpaved roads.
Four Connect 50mm²: Voltage Stabilization Integrated
Four Connect supplies cables with built-in voltage stabilization. Thanks to a special conductor geometry, the conductivity is increased along the entire cable length, protecting the car audio system from voltage fluctuations. This is especially useful for high-power amplifiers in large car sound configurations.
Ground Zero 50mm²: High Flexibility in Focus
Ground Zero 50mm² power cables are very robust and extremely flexible. They can be closely adapted to the vehicle structure without causing breaks or damage. Additional coatings protect the conductor from mechanical influences.
Masori 50mm²: Maximum Performance for Car Hi-Fi
The in-house Masori cables in 50mm² version impress with a highly pure copper quality and an all-around sheath. The manufacturing tolerance is very low, ensuring consistently low resistance. The result: constant voltage supply at all volume levels and minimized sound loss.
Sky High Car Audio 50mm²: Premium for High-End Installations
Sky High Car Audio cables offer excellent signal purity and pronounced interference resistance. The outer insulation is thicker than that of many other cables, reducing negative environmental influences. Ideal for competition installations where every decibel counts.
Laying and Installation Tips for 50mm² Power Cables
The correct installation of a 50mm² cable greatly affects the overall performance in car audio. When routing, pay attention to keeping the paths as short as possible and minimizing bends or kinks. Plan the vehicle interior so that the cable:
- no sharp edges touched
- not running near hot components (engine, exhaust pipes)
- always secured with cable ties or clamps
- because immediate protection is provided by fuses located near the battery
Especially with plug-and-play solutions for VW, Opel, SEAT, or Audi, pre-configured sets make installation quick and easy. Those who want to be on the safe side can trust the installation service in Frankfurt Oder at Masori. There, professionals handle the installation and ensure absolutely expert integration into the vehicle.
Important accessories for the 50mm² cable connection
To connect the 50mm² power cable to the car audio system, extensive accessories are recommended that facilitate installation and increase safety:
- Cable lugs and ring terminals for battery and ground connection
- High-quality fuse holders (ANL or Mini-ANL) with appropriately sized fuses
- Control voltmeters to monitor the voltage
- Additional cable ducts or cable trays against abrasion
- Heat shrink tubing for protection against moisture and short circuits
For amplifiers with special terminal sizes, reduction adapters or suitable connection clamps are also advisable. This prevents loose contacts and allows optimal use of the cross-section.
Performance Data and Impedance: What Are the Differences?
A 50mm² power cable usually has an impedance in the range of ≤ 0.1 ohms per defined length. Cheaper variants may have slightly higher values, which leads to minor losses. For very large amplifiers from 2000 watts RMS, it is therefore advisable to invest in branded products to minimize voltage drop as much as possible. As a result, the amplifier receives the constant supply it needs for solid power reserves. This allows subwoofers and speakers to operate at a high sound level without any loss of performance.
Advantages of lower impedance:
- Constant amplifier supply
- Minimal voltage drop under high load
- Less heat generation in the cable
- Always clear output performance
Tips on Placement and Length
Depending on the car model, the location of the amplifier varies. In vehicles with existing equipment, the trunk is often the best choice. These tips help:
- Choose the most direct route possible from the battery to the installation location
- Avoid positions near fuel lines (safety aspect)
- Route the ground cable back in a similar dimension to avoid ground loops
- Always take a few centimeters more cable to avoid unnecessary tension.
If the cable is too long, it can be easily shortened. The basic rule is: the shorter the 50mm² power cable, the lower the resistance. This keeps the voltage drop to a minimum.
Car audio single-room scenarios and special features
If you use multiple amplifiers or an active 3-way system, the power consumption increases significantly. It is worthwhile to also use 50mm² for all other power and ground connections. For particularly compact vehicles like the VW Polo or SEAT Ibiza, it may be advisable to use Y-distributors to supply multiple amplifiers evenly. With more space available, such as in a BMW 5 Series Touring or a Mercedes V-Class, installation is usually easier. In these cases, underbody areas or side panels can be utilized.

Future-proof expansion thanks to 50mm² cross-section
A decisive advantage of the 50mm² power cable lies in its future-proof expansion. Those who initially only retrofit one amplifier, but may later add new subwoofers or additional channels, will have little effort with the retrofit thanks to a sufficiently sized cable. Upgrades such as more powerful amplifiers or high-performance DSP amplifiers also benefit from the enormous reserve that a 50mm² cable provides to the audio system.
Variants, Lengths, and Modularity
Whether in 3-meter, 5-meter, or 10-meter lengths – Masori offers these cables in various cuts. Those who need more flexibility can order sets with adapters, ring terminals, and heat shrink tubing to cut the cable precisely to the vehicle's dimensions. This eliminates the hassle of having to buy additional individual parts later.

This is how sound quality is improved
The electrical supply is the heart of every car audio system. As soon as the current flow remains stable, amplifiers reach their rated power, and speakers can perform without any drop in volume. A 50mm² power cable ensures that even at high volumes, there is no drop in the base voltage:
- Less distortion at high levels
- Constant frequency response
- Better dynamics and impulse response
- No flickering of the headlights due to voltage drop
