Match Your Car Speakers & Car Amplifier

Match Your Car Speakers & Car Amplifier

Car amplifiers boost the signal your stereo sends to your car speakers, driving your speakers with an independent power source. There are two power ratings you'll notice when shopping for a car amplifier: root mean square (RMS) power and peak power.

• RMS power: RMS power measures the amount of continuous power a car amplifier uses to drive your speakers. Prevent car speaker damage by ensuring that the RMS power on your amplifier matches the RMS power rating on your speakers and subwoofer.

• Peak power: Peak power refers to how much wattage a car amplifier has available for short and sudden increases in sound. The number will always be higher than RMS.

There are three types of car amplifiers: mono, two-channel, and four-channel.

• Mono car amplifiers: Mono amplifiers power a single speaker.

• Two-channel car amplifiers: Two-channel car amplifiers boost the signal to two speakers and a subwoofer.

• Four-channel car amplifiers: Four-channel car amplifiers boost the signal to four speakers and two subwoofers; two speakers and a single subwoofer; or any configuration in between.

Hunt down the best car amplifier for your music and your car on eBay Australia.

• Get good bass: If you love good bass, make sure your car amplifier has a low-pass filter that only sends low-frequency notes to your subwoofer. It will keep your subwoofer from trying to reproduce high notes.

• Improve high-frequency audio:Car amplifiers with built-in high-pass filters prevent your tweeters from trying to reproduce low-frequency sounds.

• Look for speaker-level inputs: Most car stereos installed at the factory have a basic built-in amplifier. Search for a car amplifier with speaker-level inputs that can process these already-amplified signals.

• Provide extra amplification:You are able to connect one car amplifier to another to drive different speakers. If you want a multi-amplifier system, make sure your primary amplifier comes with a preamp output so that you can send a signal to your secondary amp.

Shop for either new car amplifiers or used car amplifiers on eBay Australia. Buying a used amplifier can save you money, and you can find recent models; audiophiles regularly upgrade their equipment and sell their used amplifiers at a significant discount.

Accessorise Your Car Amplifier

Accessorise Your Car Amplifier

You only need a few accessories to make your car audio system stand out or to make installation easier.

• Remote controls: Use remote controls to control your car amplifier, even if you mount it in your car boot.

• Voltage monitors: See exactly what your car audio system is doing at all times with voltage monitors. There are some that even monitor temperature.

• Control centre: A control system monitors and regulates the flow of electricity to your components on high-end systems. It also contains fuses to help prevent catastrophic shorts, which can damage your car audio equipment.

• Custom covers and car amplifier bridges: Make your system look good with custom covers and car amplifier bridges. Some amplifier bridges also work as expanded heat sinks to keep your car amplifier cool.

• Car wiring kits: Car wiring kits come with all the wires and fuses you will require to safely install and operate your car amplifier. Ensure the rating of the fuse works for the power level of your amp.

• Line-output converters: If your car stereo doesn't have RCA jacks, use your amplifier's built-in converter or an external line-output converter to lower the stereo signal so that your amplifier can use it.

Install Your New Car Amplifier

Install Your New Car Amplifier

There are different installation instructions for every car amplifier. Allow your installation documentation to guide you and remember some basic rules in mind when you install your new amp.

• Choose amplifier location wisely: Install your amplifier more than 90cm from your radio under a front seat or in your car boot. The electricity flowing through the amplifier can interfere with reception if you install it too close to your radio.

• Ventilate your amp: Make sure your amplifier is placed somewhere with proper ventilation. The cooling fans built into most amplifiers circulate air to keep the component cool. Make sure the amplifier has at least 5cm of clearance under a seat. If you decide to install your amplifier in your car boot, make sure to mount it right side up.

• Use the stereo preamp output:You should connect your car amplifier to the RCA jacks found at the back of your stereo. The stereo preamp output sends an unprocessed music signal to your amp. If your car stereo doesn't have RCA jacks, use an external line-output converter to lower the stereo signal and produce a signal your amplifier can use.
