Car Audio Build Shopping List
71 distinct parts across 6 builds. Updated .
How to use this
Find the build closest to what you are doing and work down its list. Every line is a link and every group carries its own subtotal, so you can see what each part of the system costs before committing to the whole thing. Nothing here is padding: if you buy a build's list, you can finish the install.
The one item on every list that people are tempted to skip is the main fuse and its holder. Do not. It goes within 18 inches of the battery positive terminal, it protects the wire rather than the equipment, and the cable between the battery and the fuse is the only unprotected part of the whole system.
A First Bass System, Done Properly
Read the full build, which explains what to skip and what to upgrade first. A complete first subwoofer system for a car with a factory head unit: one sealed 12, a monoblock, a line output converter and every wiring part needed to finish the job.

True spec 0 AWG with a 17 foot run and two fuse values. A truck run from battery to cab is longer than it looks.

Two monoblocks rather than one, so each driver gets its own amplifier and its own load.

Directional shielding, which is the correct construction for a cable sharing a car with a 400 amp alternator.
-
B2 AudioB2 Audio 4v 10 channel

The electrical system, which is the actual build

Tools, and these are not optional here
$199.72- Brileine
Brileine 10 ton hydraulic crimper
Hydraulic crimping. A hammer crimp on one of thirty connections at 300 amps is a resistance heater waiting to happen.

A sound level meter, so you know what you are exposing yourself to.

Researched guidance, not professional advice. Prices come from the Amazon catalog at the time this page was built and change often. Check the fitment list on any vehicle specific part against your own year, engine and body before ordering, because we cannot tell you whether a part fits your vehicle. A car battery delivers hundreds of amps into a short: fuse within 18 inches of the positive terminal, disconnect the battery before running power wire, and use a grommet through every panel.
