Professional-grade calculators and design tools to help you build the perfect car audio system.
Design sealed and ported subwoofer enclosures using Thiele-Small parameters. Compare enclosure types and get optimal box dimensions.
Launch ToolCalculate combined impedance for series, parallel, and series-parallel subwoofer wiring with visual diagrams.
Launch ToolFind the correct AWG wire gauge for your car audio amplifier based on current draw, cable length, and OFC vs CCA wire type.
Launch ToolFind the right amplifier power for your subwoofers based on RMS ratings and impedance.
Launch ToolCompare subwoofer configurations by cone area. Settle the"6 12s vs 3 18s" debate once and for all!
Launch ToolCalculate how power changes affect SPL. Essential for understanding amplifier upgrades and competition goals.
Launch ToolCalculate voltage, current, resistance, or power. Enter any two values to find the others.
Launch ToolCalculate your electrical system's capacity. Add alternators and batteries to see if you can support your amplifiers.
Launch ToolDesign DIY lithium battery packs for car audio. Calculate series/parallel configurations for your target voltage and current.
Launch ToolCompare strapped (bridged) vs gain matched amplifier configurations. See power output differences and learn which setup is right for your goals.
Launch ToolCalculate delay values for your DSP to time-align all speakers. Enter distances from each speaker to your ears for optimal staging and imaging.
Launch ToolEstimate the total cost of a car audio system. Select your vehicle, bass level, quality tier, and components for an instant hardware cost breakdown with electrical requirements.
Launch ToolOur calculators use formulas and methodologies from Vance Dickason's Loudspeaker Design Cookbook, the industry-standard reference for speaker enclosure design. Combined with our database of Thiele-Small parameters, you get accurate, professional-grade results.
