Factory or stock speakers are usually made of poor materials like cheap plastic and produce low-quality sound. In contrast, aftermarket speakers use high-quality components like polypropylene, Kevlar, and rubber surrounds, and produce a clearer, richer, and louder sound.
Your factory car audio system may require an upgrade when it begins distorting at higher volumes, sounding flat or lacking bass. You also need an upgrade if it is an old model and lacks modern features such as Apple CarPlay and Android Auto.
The best sound quality can be experienced by upgrading the factory speakers first. Replacing them with top-tier aftermarket speakers not only improves clarity and bass response, but also improves the overall sound quality immediately.
The time required for a car audio upgrade depends on the part you are installing. While a simple head-unit replacement can take 1 to 2 hours, a full upgrade with speakers, an amplifier, and a subwoofer typically takes 4 to 6 hours depending on your vehicle type and wiring layout.

An amplifier enriches your audio experience by providing clean and powerful sound and preventing distortion at higher volumes. It allows speakers and subwoofers to perform at their best, especially in premium or custom audio setups.
While a mono amp powers the subwoofer, multi-channel amps (2, 4, or 5 channels) power your audio system, including the speakers or a combination of speakers and a subwoofer.
Yes. At Maximum Sound & Security, we sell the top-quality, reliable amplifiers in NZ from premium brands like Kicker, Morel, ZeroFlex and more, which boost your music listening experience even at higher volumes.
While it is not always required, the amplifier will help the expensive aftermarket speakers perform at their best. It delivers clean power that factory head units cannot provide.
No. As long as the amplifier is correctly installed and matched to your vehicle’s electrical system your car battery will not be drained. Proper wiring ensures safe power consumption.
To choose the right amplifier you should:
- Match the amp’s RMS power output to your speakers or subwoofer,
- Consider the number of channels you need,
- Ensure it is compatible with your head unit.
Common telltale signs of poor-quality speakers include distortion at higher volumes, weak bass, audio cutting in and out and crackling sounds. If you experience any of these problems, start looking into aftermarket speakers from premium brands.
Coaxial speakers combine the woofer and tweeter in one unit, and the component speakers separate them for better clarity, imaging, and overall sound quality.
Yes. At Maximum Sound & Security, we sell the best speakers from major brands like Alpine, Kenwood, Morel, Kicker and more. Even with a factory head unit, our speakers will enhance your music listening experience by producing clearer highs, stronger mids, and tighter bass.
Yes. As speakers come in different sizes and mounting depths our technician will check your car’s door and dash measurements to ensure an accurate fit.
When you are purchasing aftermarket speakers, look for woofers made of polypropylene or Kevlar and tweeters made of silk or metal as they tend to offer better durability and sound performance.
After you replace your factory speakers with our high-quality ones, they will somewhat boost the bass. However, for deep, low-frequency power, adding a subwoofer is the best option.
Most installations take 1 to 2 hours depending on the number of speakers, model of the vehicle, and whether wiring or mounting modifications are needed.
Yes. A subwoofer adds depth and balance to the sound from your audio system by handling low frequencies that regular speakers cannot produce. It improves all music genres, including pop, jazz, and classical.
Yes. You will need to purchase a good quality amp along with your subwoofers because they require dedicated power. A mono or multi-channel amplifier will ensure the subwoofer performs correctly without straining your car’s electrical system.
Sealed subwoofer boxes provide tight, accurate bass, while ported subwoofer boxes deliver louder, deeper bass. Your choice will depend on your preferred music style and sound preference.
Not necessarily. At Maximum Sound & Security, we have subwoofers that come in compact enclosures, spare-wheel designs, and slim under-seat options, saving space while still boosting bass.
Yes. With the right line-out converter or integration device, our technicians can add a subwoofer to your existing factory head unit without replacing it.
