Audio Technology
Sound begins with a complete signal path
Audio moves from a source through processing and amplification before reaching the speakers. Understanding that path makes it easier to see why stereos, amplifiers and speakers need to work together.
Source
The stereo, phone or Bluetooth adapter provides the media signal.
Amplification
Amplifiers increase signal power before it reaches compatible
speakers or subwoofers.
Output
Speakers and subwoofers convert the electrical audio signal into
sound inside the cabin.
Navigation Technology
Displays bring digital information into view
GPS devices and connected displays provide maps, media controls, communication features and phone integration through a dashboard or portable screen.
GPS Guidance
Dedicated navigation devices can provide route information without
relying entirely on the vehicle stereo.
CarPlay & Android Auto
Connected displays place supported phone applications into a
driving-focused interface.
Bluetooth
Wireless pairing can carry calls, media and control information
between personal devices and the vehicle.
Awareness Technology
Extra visibility can come from several directions
Cameras and parking systems extend the information available to a driver by recording the road, displaying rear views or detecting nearby obstacles.
Dash Cameras
Record the forward road view and, depending on the system,
additional angles around the vehicle.
Backup Cameras
Add a rear-facing view through a compatible screen or monitor.
Parking Sensors
Use proximity information to provide alerts around selected areas
of the vehicle.
Diagnostic Technology
Vehicle data turns warning signs into information
OBD-II scanners and monitoring systems help expose vehicle information that is normally hidden behind dashboard indicators and onboard electronic systems.
OBD-II Scanners
Connect to supported vehicle diagnostic systems to retrieve codes
and available operating data.
TPMS Monitoring
Provides tire-pressure information through compatible sensors and
monitoring displays.
Live Data
Some diagnostic tools can display supported vehicle parameters
while the system is operating.
Power Technology
Power products solve different electrical needs
Charging a battery, starting a vehicle, converting DC power and charging a phone are different tasks even though they all depend on the vehicle electrical system.
Battery Support
Chargers help maintain or restore compatible vehicle batteries.
Emergency Starting
Portable jump starters provide temporary starting power when
appropriately matched to the vehicle.
Device Power
Inverters, USB chargers and wireless chargers support personal
electronics inside the cabin.
Audio technology is built as a chain
Source quality, amplification and speaker capability all influence the
final sound heard inside the cabin.
Audio & Media
From digital signal to cabin sound
Modern car audio combines media sources, digital connections, amplification and speakers. Upgrading one part of the system can change the requirements of the others.
Car Stereos
Act as the control center for media sources, audio settings and
connected-device functions.
Car Amplifiers
Increase electrical signal power so compatible speakers and
subwoofers can operate effectively.
Car Speakers
Convert amplified electrical signals into audible sound throughout
the cabin.
Car Subwoofers
Handle lower-frequency sound and often require dedicated amplification
and enclosure space.
Bluetooth Adapters
Add wireless media or communication capability to compatible existing
audio systems.
Cameras & Awareness
Technology can extend what the driver can see
Cameras and sensors turn information around the vehicle into images, recordings or alerts. Their usefulness depends heavily on placement, viewing angle and the way information reaches the driver.
Dash Cameras
Capture video of the road and may support additional recording,
storage or monitoring features.
Backup Cameras
Provide a rear-facing image through a compatible display.
Parking Sensors
Detect nearby objects within supported sensor zones and provide
distance-related alerts.
Display Position
Determines where visual information appears and how easily it can be
viewed without unnecessary distraction.
Power Connection
Supplies the camera or sensor system and can influence how and when
the device operates.
Placement shapes the information a camera captures
A camera's viewing position affects both road coverage and the usefulness
of the recorded image.
Diagnostics translate vehicle systems into readable data
Scan tools can make supported fault codes and operating information
easier to access and review.
Diagnostics & Monitoring
Vehicle data adds context to warning signals
Modern vehicles continuously exchange electronic information between onboard systems. Diagnostic and monitoring products provide a way to access selected parts of that information.
OBD-II Port
Provides a standardized diagnostic connection on compatible vehicles.
Fault Codes
Indicate diagnostic conditions detected and stored by supported
onboard systems.
Live Data
Some scanners can display available values reported by vehicle
sensors and control modules.
TPMS Systems
Monitor supported tire-pressure information through compatible sensor
configurations.
Wireless Scanners
May use Bluetooth or another wireless connection to display supported
information on a phone or tablet.
Power & Charging
Electrical technology supports the entire cabin
Vehicle power products range from battery support and emergency starting to converting electrical output for portable electronics. Choosing the right category starts with understanding the job it needs to perform.
Battery Chargers
Supply controlled charging to compatible vehicle batteries.
Jump Starters
Provide portable emergency starting assistance when matched correctly
to the vehicle.
Power Inverters
Convert vehicle DC electricity into a form suitable for compatible
AC-powered equipment.
USB Chargers
Deliver device charging through supported USB standards and output
levels.
Wireless Chargers
Transfer compatible charging power without a cable plugged directly
into the phone.
Power products serve different electrical jobs
Battery support, emergency starting and accessory charging require
different output and connection considerations.
How Systems Connect
One device can depend on several technologies
A modern automotive electronics setup often combines power, data, wireless communication, audio and display technology. Thinking in systems can make product selection and installation planning much clearer.
Phone → Display → Audio
A connected screen may receive information from a smartphone, display navigation and send media through the vehicle audio system.
Camera → Signal → Screen
Backup-camera technology depends on the camera position, a signal path and a compatible display that can present the rear image.
Source → Amplifier → Speakers
Audio performance depends on how the signal moves from the source through amplification to compatible speakers and subwoofers.
Vehicle → Scanner → Information
An OBD-II scanner reads supported vehicle information and converts it into codes, values or on-screen diagnostic data.
Vehicle Power → Device
Inverters and charging accessories convert or distribute available vehicle power for compatible personal electronics.
Sensor → Monitor → Alert
TPMS monitoring systems use compatible sensors to provide tire-pressure information through a display or connected interface.
