1-channel amplifiers, 2-channel amplifiers, and 4-channel power amps

Quartorigo's amplifier range targets enthusiasts seeking extensive power in their car. A 1-channel amplifier (up to 1000 W RMS at 2 Ohms), often called a monoblock, is ideal for subwoofers as it can cover low frequencies down to 20 Hz. The 2-channel amplifiers (from 2×100 W RMS up to 2×400 W RMS) offer flexible bridging options to operate, for example, a 10-inch subwoofer together with a 6.5-inch mid-bass driver. The 4-channel amplifiers (often equipped with 4×50 W to 4×150 W RMS) allow two channels to be used for dome tweeters and the other two for 3-inch midrange drivers or 8-inch mid-bass drivers. Thanks to Class-A/B or Class-D technology, low distortion values (under 0.1% THD) and high efficiency can be combined.

• 1-channel monoblocks with high-level input for easy integration into factory radios
• 2-channel amplifiers with variable low-pass and high-pass filters
• 4-channel models with integrated DSP for precise crossover settings
• Thermal protection circuits and multi-stage cooling

Subwoofers for powerful bass: 10" (25 cm) bass experts

In the 10-inch (25 cm) subwoofer category, Quartorigo delivers robust solutions with 2 Ohm or 4 Ohm voice coils, power handling up to 600 W RMS, and mechanical excursion (Xmax) up to 14 mm. The cone is partly made of treated paper fibers combined with generous ferrite or neodymium magnets. A separate amplifier ensures precise pressure in the lower frequencies between 20 Hz and 45 Hz. Plug & play options simplify installation even in tight trunk spaces. For optimal airflow, CNC-milled housing elements are integrated, preventing distortion and thermal issues.

• 2" (50 mm) voice coil for higher power handling
• CONE FACTOR: Stiffness-optimized materials for lower resonance
• Fine-tunable installation parameters for sealed or bass reflex enclosures
• Sensitivity around 85 dB for powerful performance

Speakers: dome tweeters, midrange drivers, and mid-bass drivers

Quartorigo develops dome tweeters (1 inch) with silk or titanium diaphragms and a frequency range up to 25 kHz. A low resonance point around 1.2 kHz guarantees clear highs without distortion. Midrange drivers in 3" (8 cm) design are perfect for precise vocal reproduction at frequencies from 500 Hz to 5 kHz. Thanks to wide dispersion characteristics and high sensitivity, these midrange drivers can be efficiently operated with just 40 W RMS. For strong mids and solid bass portions, 6.5-inch mid-bass drivers work from 50 Hz to 4 kHz and can handle up to 100 W RMS. In the 8" (20 cm) variant, the cone achieves higher excursion at 150 W RMS while maintaining a compact design.

Additional components such as crossovers, damping material, or mounting adapters complete the range. This allows individually tuned acoustic solutions to be realized in almost any vehicle – from compact cars to sedans.

Installation, accessories, and professional support

A complete car audio upgrade succeeds with the right tools, wiring kits (e.g., 20 mm² to 50 mm² cross-section), and robust fuses to ensure all components are optimally powered. High-quality RCA connections minimize interference. Those needing assistance can contact the expert support or consult the AI chatbot to check the compatibility of Quartorigo components with the respective vehicle. The option for professional on-site installation in Frankfurt Oder provides additional security for particularly demanding setups. This way, the desired setup – from a 1-channel monoblock for the 10" subwoofer to a complete 3-way system – can be precisely configured and integrated into the car without sound loss.
