Covers schematic symbols, wire colour conventions, and connector pinout charts. Enables learners to locate factory audio circuits without damaging vehicle wiring.

Lesson 4 • Tool Selection and Workspace Setup

Identifies hand tools, power tools, and diagnostic instruments required for audio fitment. Proper workspace organisation reduces errors and fitment time.

Lesson 1 • Amplifiers and Signal Processing

Surveys amplifier classes, channel configurations, and onboard processors. Prepares learners to match amplifiers to speakers and head units.

Lesson 2 • Speakers and Transducer Types

Introduces full-range, component, coaxial, and subwoofer designs. Explains how transducer type determines placement and amplifier requirements.

Lesson 3 • Wiring and Connector Fundamentals

Introduces wire gauges, connector types, and basic circuit concepts. Provides the electrical vocabulary needed for all subsequent fitment chapters.

Lesson 4 • How Vehicle Audio Systems Work

Covers the complete signal chain from head unit to speaker. Establishes the conceptual framework used throughout the entire course.

Lesson 1 • Factory Head Unit Removal

Covers DIN-release tool use, antenna adapter removal, and factory harness disconnection. Proper removal prevents broken clips and damaged factory connectors.

Lesson 2 • Antenna and Navigation Integration

Covers AM/FM antenna adapters, GPS antenna placement, and signal amplification. Correct antenna integration ensures reliable reception and navigation accuracy.

Lesson 3 • Steering-Wheel Control Retention

Explains SWC interface modules and programming procedures for common vehicle platforms. Retaining steering-wheel controls is a key customer satisfaction requirement.

Lesson 4 • Head Unit Mounting and Trim Fitment

Demonstrates dash kit selection, head unit securing, and trim panel reinstallation. Professional fitment eliminates rattles and presents a factory-quality appearance.

Lesson 1 • Door Speaker Mounting Techniques

Covers adapter ring use, speaker baffle installation, and weatherproofing for door environments. Proper mounting maximises bass response and protects speakers from moisture.

Lesson 2 • Rear Fill and Deck Speaker Installation

Addresses rear deck speaker sizing, grille fabrication, and integration with front staging. Rear fill enhances soundstage depth without overpowering front speakers.

Lesson 3 • Speaker Selection and Compatibility

Matches speaker specifications to factory openings, power sources, and listening goals. Correct selection prevents underpowering, overpowering, and fitment failures.

Lesson 4 • Component Speaker System Wiring

Explains passive crossover placement, tweeter mounting options, and bi-amp configurations. Correct crossover wiring ensures proper frequency distribution to each driver.

Lesson 1 • Gain Setting and System Calibration

Demonstrates voltage-based gain setting using a multimeter and oscilloscope. Correct gain structure maximizes dynamic range and prevents clipping distortion.

Lesson 2 • Signal Cable Routing and Noise Prevention

Teaches RCA cable routing, separation from power cables, and ground loop elimination. Clean signal routing is the primary defense against alternator whine and interference.

Lesson 3 • Fusing and Circuit Protection

Explains fuse placement rules, fuse types, and distribution block wiring. Correct fusing protects wiring from fire in the event of a short circuit.

Lesson 4 • Amplifier Placement and Mounting

Evaluates boot, under-seat, and custom mounting locations for thermal and space efficiency. Correct placement prevents overheating and simplifies power wiring runs.

Lesson 1 • Listening Evaluation and Final Adjustments

Applies critical listening with reference tracks to validate measurement-based tuning. Combines objective data and subjective evaluation for a complete tuning workflow.

Lesson 2 • Equalizer Types and Applications

Compares graphic, parametric, and digital equalizers and their use cases. Equalizer selection directly affects tuning precision and system flexibility.

Lesson 3 • Measurement Tools and Techniques

Introduces real-time analyzers, measurement microphones, and sweep tones for objective tuning. Measurement data guides EQ decisions and confirms crossover accuracy.

Lesson 4 • Time Alignment and Imaging

Covers delay-based time alignment to create a centered soundstage from an off-axis listening position. Proper alignment is the most impactful tuning step for sound quality.

Lesson 1 • Amplifier Upgrades in OEM Systems

Demonstrates replacing or supplementing factory amplifiers while preserving OEM signal processing. Correct integration avoids double-EQ artifacts and maintains factory tuning intent.

Lesson 2 • Retaining Backup Cameras and Safety Systems

Addresses camera input adapters, trigger wire integration, and parking sensor retention. Safety system retention is a legal and liability requirement in most markets.

Lesson 3 • OEM Infotainment System Architecture

Maps factory amplifier, DSP, and infotainment network topologies in modern vehicles. Understanding OEM architecture is prerequisite to any integration or upgrade strategy.

Lesson 4 • CANBUS and Data Interface Modules

Covers CANBUS communication basics and interface module programming for vehicle-specific data. Modules enable speed-dependent volume, chime retention, and factory display integration.

Lesson 1 • Common Noise and Interference Faults

Identifies alternator whine, ignition tick, and HVAC interference by their acoustic signatures. Each noise type has a specific electrical cause and targeted remedy.

Lesson 2 • Head Unit and Integration Faults

Addresses no-power, no-audio, and feature-loss faults in head unit and integration installs. Systematic testing of harness adapters and interface modules resolves most integration faults.

Lesson 3 • Quality Control Inspection and Sign-Off

Establishes a pre-delivery inspection checklist covering wiring, fitment, and system performance. A documented sign-off process protects the installer and builds customer trust.

Lesson 4 • Amplifier and Speaker Fault Diagnosis

Covers protection mode triggers, thermal shutdown, and speaker voice coil failure diagnosis. Correct diagnosis prevents replacing functional components unnecessarily.
