The Car Audio Build & Tuning Planner
Plan the build and the budget by tier from this site's own build pages, wire the power and ground the way the NEC ampacity tables and this site's own calculators size them, size the box and port from the driver's own published Thiele/Small parameters, and set the gain by a number instead of by ear: a car and system at-a-glance card, a build plan and budget by tier, a power and wiring plan, a speaker and enclosure sizing sheet, an installation checklist, a gain setting and tuning guide, a reusable listening test and tuning log, a troubleshooting sheet, a maintenance log and a budget planner.
- 10 fill-in worksheets, 29 print pages
- 2 filled-in examples to copy the format from
- Companion Excel / Google Sheets tracker with the wire gauge and box volume formulas built in
- Online buyer guide with budget ranges and Amazon links, by build tier
Replaces the guessed wire gauge, the fuse sized to the amplifier instead of the wire, the gain set by ear, and the ground point picked without checking for bare metal.
30-day money-back guarantee. Use it all; if it doesn't help, every dollar back.

Also included
- 2 filled-in example worksheets. Power & Wiring Plan and Speaker & Enclosure Sizing Sheet, worked through with hypothetical numbers, so you can see a finished page before you start.
- 1 bonus printable. Quick Reference: Wire, Fuse & Gain: The published standards and conventions this kit is built from, cut down to glovebox size
- 1 companion spreadsheet. An editable workbook: an amplifier current draw, wire gauge and fuse calculator using this site's own formulas, a sealed and ported box volume and port length calculator using the same Thiele/Small and Helmholtz relations the site's calculators use, a one-time system budget with a running total, and a reusable maintenance log. Tabs: Power & wiring calculator, Box volume & port calculator, Budget, Maintenance log.
- 1 start-here page. The three sheets to fill in the first 20 minutes, and which sheet to reach for when.
Plus the online buyer guide
Three complete build tiers at three budgets, every item priced and linked, plus every product the kit names, kept current on this site. Your kit links straight to it, so the prices you plan with are today's, not the day the PDF was printed.
Who it's for
- Anyone planning a first bass system who wants the wire gauge and fuse sized to the amplifier's real current draw instead of guessed
- Anyone building a sealed or ported box who wants the Thiele/Small math worked through with a real, verified example
- Anyone who has never set gain with a multimeter and wants the exact voltage target and the step-by-step procedure
- Anyone chasing an alternator whine, a clipping amplifier, or a protect-mode shutdown who wants the one-test diagnosis instead of guessing at parts
- Anyone building the same car's system over several weekends who wants a reusable tuning log and maintenance log
Who made this
Built by the CarAudioCalc team from the same amplifier current draw, wire gauge, sealed and ported box volume, and gain setting formulas the free site's calculators run on, laid out as a workbook to fill in with your own car's real numbers rather than a page to read.
30-day money-back guarantee

Questions
Does this tell me if a specific part fits my specific vehicle?
No. Fitment is what the manufacturer listing is for, and this kit does not guess at it. It is the same arithmetic as the free site's calculators, run on YOUR own amplifier ratings, driver parameters and run lengths.
Does this replace the free site?
No. The free site has the calculators, build pages and reference charts; the kit is where your own car's numbers get written down, dated and reused, plus the budget tracker and reusable logs the free pages do not carry.
I have never set gain with a multimeter before. Is this still useful?
That is exactly who the Gain Setting & Tuning Guide is for: it walks through the voltage math in order, with the setup steps and a checkpoint list, and does the arithmetic for you once you have your own amplifier's RMS rating and load.
Does it cover local noise ordinances?
It includes a reminder to check them before running a system at volume, but it does not publish a city-by-city table, because rules genuinely vary and change; check your own local ordinances.
Printable or fillable on screen?
Both. Print it and write by hand, or open a worksheet PDF in a reader that supports typing and fill it on a tablet or phone.
What if it does not help?
Use the whole kit for 30 days. If it does not help, the refund form on the contact page gets every dollar back, no questions asked. Refund form.
