If you're starting from scratch, pairing an amplifier with our speakers and exploring the wider gadgets and electronics range gives you most of what you need in one place. These cheap amplifiers ship fast across Australia, backed by a 12-month warranty and support available seven days a week from 8am to 8pm.

Audio Amplifiers for Home Cinema and Stereo Listening

Audio amplifiers sit at the heart of any serious home entertainment setup. Whether you're driving a pair of bookshelf speakers for casual listening or building out a multi-room system, the amplifier's job is to take a low-level audio signal and boost it to a level where your speakers can work at their full potential. The category includes integrated amps with a built-in preamp and power amplifiers that work alongside a separate preamplifier, giving you options depending on how elaborate you want the system to be. For a home cinema build, pairing an audio amplifier with our projectors gives you the screen and sound combination that makes a dedicated viewing room worth the effort. If you're also mounting a screen on the wall as part of the same project, our TV wall mounts handle the hardware to keep everything in a clean, permanent position.

Guitar Amplifiers for Practice and Performance

Guitar amplifiers serve a purpose that audio amps cannot cover the same way. A guitar amp is designed to amplify an electric guitar's pickup signal, and many models go well beyond simple volume boosting: they shape tone, add warmth through valve or transistor circuitry, and often include built-in effects like reverb or tremolo. For home use, a compact practice amp keeps volume manageable while still delivering the feel that makes regular playing worthwhile. For live or session use, the choice shifts toward more output and projection. If you're fitting out a room for playing or recording, our home improvement range has the tools and hardware for the setup side of the project. For anyone also running a media setup in the same space, our DVD players sit alongside an amplifier as a signal source, which works well when the room doubles as both a practice area and an entertainment space.

Clean Power and What It Does for Audio Performance

Power supply quality affects audio performance more than most people realise. Amplifiers draw significant current, particularly at higher volumes, and if the supply is unstable or underpowered, you'll notice it in the output through hum, noise, or compression at peak levels. For most home setups a standard wall outlet is sufficient, but for outdoor use, remote installations, or setups away from fixed mains power, a portable battery power supply can keep your audio running without the noise and fluctuation risks that come with long extension leads. For permanently installed or multi-zone audio setups where signal distributes across rooms, low voltage transformers can play a role in managing how an amp drives multiple speaker zones. Checking the power requirements of your amplifier against what your setup can realistically supply is a useful step before committing to any configuration.

Taking Audio Outdoors and Into Entertainment Areas

Moving audio outdoors changes what you need from an amplifier setup. Outdoor entertainment areas, whether a patio, deck, or backyard space, typically benefit from more output than an equivalent indoor room because ambient noise, open air, and variable listening distances all work against the sound. The most practical approach is positioning a weatherproofed or sheltered indoor unit close to an outdoor speaker run, rather than placing the amplifier itself outside. If you're building an outdoor entertainment area from the ground up, planning the outdoor lighting at the same time helps the space function as well after dark as it does during the day. Adding solar-powered lights around the perimeter keeps cable runs minimal and the setup flexible without sacrificing atmosphere once the sun goes down.

How do I choose the right amplifier for my setup?

Start with what you are connecting. Check whether you need it for a home audio setup, a turntable, or a TV source, then confirm the amplifier has the right input types. Think about how many speakers you want to run and the room size. Use the product listing to match the amp’s output and connections to your gear.

Will it work safely with my speakers, and will it have enough power?

Check your speakers’ recommended amplifier range and make sure the amplifier supports your speaker type. For power, match the amp to your room size and how loudly you listen. If you cannot confirm the match, compare the specifications on both the speaker and amplifier product listings before buying.

Which specs should I compare: wattage, inputs, and size?

Compare all three, but start with inputs so you can actually connect your devices. Then check wattage per channel to suit your speakers and space, and consider the amp’s physical size for your cabinet or shelf. If you want simpler setup, prioritise clear front controls and easy connection types listed in the specs.

What cables or installation steps are needed before first use?

Before first use, check the listing for what is included and what you need to supply, like a power lead and basic audio and speaker cables. Set it up on a stable surface with plenty of airflow around it, then connect your speakers and audio source before turning it on. For your first test, start with the volume low and adjust gradually.
