Car Audio Tools

Design sealed and ported subwoofer enclosures using Thiele-Small parameters. Compare enclosure types and get optimal box dimensions.

Calculate combined impedance for series, parallel, and series-parallel subwoofer wiring with visual diagrams.

Find the correct AWG wire gauge for your car audio amplifier based on current draw, cable length, and OFC vs CCA wire type.

Find the right amplifier power for your subwoofers based on RMS ratings and impedance.

Compare subwoofer configurations by cone area. Settle the "6 12s vs 3 18s" debate once and for all!

Calculate how power changes affect SPL. Essential for understanding amplifier upgrades and competition goals.

Calculate voltage, current, resistance, or power. Enter any two values to find the others.

Calculate your electrical system's capacity. Add alternators and batteries to see if you can support your amplifiers.

Design DIY lithium battery packs for car audio. Calculate series/parallel configurations for your target voltage and current.

Compare strapped (bridged) vs gain matched amplifier configurations. See power output differences and learn which setup is right for your goals.

Calculate delay values for your DSP to time-align all speakers. Enter distances from each speaker to your ears for optimal staging and imaging.

Estimate 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.
