Build a car audio wiring diagram on a top-down view of your vehicle. Drop in amps, speakers and subs and the power, ground, signal and speaker wiring routes itself — validated before you spend a dollar on copper.
Mono amp, single subwoofer, power and ground run. The most common first build.
OEM head unit swap with a front component pair. Great starting point for sound quality.
Head unit, 4-channel amp, mono sub amp, subwoofer, and component speakers front and rear.
Head unit into a DSP for time alignment and EQ, then out to a 4-channel and mono amp. Maximum sound quality.
Drag amps, speakers, and subs onto a top-down view of your vehicle. Snap to door panels, dash, under-seat, or trunk. Rethink placement in seconds — not after you've already run the wire.
Wires follow real harness paths along the chassis, with proper distribution blocks, fuses, and ground points. No guesswork — it routes itself as you build.
Instant issue list with severity levels. Full parts list with editable prices so you know the total cost upfront. Share a read-only link with your installer.
Yes. You can plan a build, auto-route the wiring, validate it and share a link for free — and you can start without an account.
No. You add components and the planner automatically routes power, ground, signal, speaker and remote-turn-on wiring for you, then flags common mistakes as you go.
Head units, amplifiers from mono up to 6-channel, component and coaxial speakers, subwoofers, DSPs, line-out converters, distribution blocks, capacitors, batteries and fuses.
Yes. Every build has a shareable link you can post in a forum or send to an installer, and you can export the build data as well.
It validates the system as you build — flagging a battery with no main fuse, an amplifier with no signal source, amp-channel overloads and unrated fuses.
Free to use. No credit card. Build your parts list, catch every mistake, and share a read-only link with your installer.
