Frequently Asked Questions - Car Audio

What do I need to upgrade my car’s audio system?

Upgrading your car audio system can be as simple or advanced as you like. Most basic upgrades start with replacing the head unit or speakers. For better sound quality and more volume, consider adding an amplifier and a subwoofer. You may also need wiring kits, mounting brackets, and fascia panels for installation, depending on your vehicle make and model.

What does the ‘Big 3’ car audio upgrade refer to?

The ‘Big 3’ refers to three key components that significantly improve your car audio system’s performance:

Head Unit: This is the brain of your car’s audio system, responsible for audio control, media playback, and connectivity (Bluetooth, Apple CarPlay, Android Auto).
Amplifier: An amp powers your speakers and subwoofers, providing clear, loud sound without distortion, and allows you to maximise the potential of your audio system.
Subwoofer: This component handles the low frequencies, adding deep bass and enhancing your audio system’s overall sound experience.

Together, these three elements make up the core of most high-performance car audio setups.

Will any head unit fit my car?

No, not all head units fit every vehicle. You'll need to check if your car supports single DIN or double DIN units, and you may require a compatible fascia kit or wiring harness for a seamless installation. At Supercheap Auto, we offer vehicle-specific products and accessories to help you find the right fit. Not sure which head unit is suitable for your vehicle make and model? Simply enter your car rego into our ‘My Garage’ feature to see which products are compatible.

Can I install car audio components myself?

Yes, many car audio upgrades can be installed at home with basic tools and some DIY knowledge. Head units, speakers, and subwoofers can typically be installed using wiring kits and online guides. A simple upgrade like replacing a head unit is easy for most DIY’ers. However, for more complex installs like adding amplifiers or subwoofers, or custom setups, professional installation might be a better option. Supercheap Auto has all the parts you need, plus friendly in-store help if you need guidance.
