How to Buy Used Car Stereo Head Units

Some cars are so old that they only have a cassette tape player, while other cars only need a slight upgrade to have a more luxurious stereo head unit. Whether the stereo is being changed to offer a CD player, an auxiliary plug, or satellite radio, replacing the car stereo head unit is simple. Finding a nice car stereo, on the other hand, can be challenging, especially when working with a tight budget. While brick and mortar electronics and automotive stores offer plenty of nice, new stereo head units, they do not offer any used ones, at least not in most cases. Fortunately, plenty of retail websites like eBay sell car stereos in both new and used condition.

These days, consumers do not have to give up quality and features for affordability. They do, however, need to know a little about car stereo head units and their many available features in order to decide what they want and determine a proper budget based on their wants and needs.

What to Look for in a Car Stereo

Before shopping for a car stereo head unit, it is first important to decide what type of a head unit is needed. There are several things that should be considered when looking around, such as the set budget, the sound quality, the unit's display, and its ability to support technology like a cellular device or mp3 player.

Budget

Regardless of the features that are desired, one's personal budget for a stereo head unit ultimately determines what can be purchased. Used car stereo head units are vastly more affordable than brand new units, and this gives the buyer more freedom to choose what he or she likes, rather than worrying about the price. Regardless, a budget should be set before browsing the selection.

Compatibility

Besides budget, the other consideration that cannot be controlled is whether the stereo head unit is compatible with one's car. Cars have predetermined stereo space, and a new car stereo head unit needs to fit in that space. The size of the stereo head unit is determined by the DIN, which refers to the standard car stereo measurement. A single DIN unit measures about 2 inches by 7 inches, while double DIN units measure 4 inches by 7 inches.

Sound Quality

The whole purpose of a car stereo is to play sound, whether it is music, talk radio, or a hands-free phone call. When comparing stereo head units, there are several ways to determine sound quality, especially when it is not possible to test the sound in a store. First, the power capabilities of a head unit determine how loud the sound can be played. The power is measured in watts, indicated by a 'W' on packaging. The larger the number before the 'W', the more power a stereo has and, thus, better quality of sound.

Finding a stereo with high and low pass crossovers between 60 Hz and 100 Hz allows for better quality in sound, as well. A stereo head unit with a high number of parametric bands allows the user to alter the sound of a stereo to fit the music playing. For the more expensive head units, a feature called alignment can be found that produces sound quality that is as rich as its price.

Sound quality can also be improved by the speaker system. These systems are called two-way, three-way, and four-way speaker systems. The higher the number of speakers, the crisper and better the quality of the sound.

Technology Support

Because technology is constantly advancing, a large majority of purchases, including car stereo head units, become obsolete quickly. Investing in a unit with a USB port or auxiliary cable connection allows for both current and future technology, whether it is the newest smartphone or a future mp3 player, to be connected, and this ensures that the money put into the car's stereo head unit remains a smart purchase for years to come.

Having a USB port also gives the stereo head unit the ability to charge cellular devices and mp3 players without the user needing to spend more money on a cigarette lighter charger. Most cellular devices and mp3 players come with USB charging cables by default.

Other features support technology like GPS and satellite radio and allow external screens for watching movies in the back seat for children. The level of technology support that is needed depends on the buyer. Regardless of the level of user knowledge, buying a stereo head unit that provides flexibility in technology features is highly recommended.

Display

One of the most essential factors to consider is the display of the head unit. A user's preference for a few buttons, a round dial for volume, or being able to see the display when the sun hits the stereo is an important aspect when it comes to purchasing a car stereo head unit. Reading reviews about a stereo's performance is a possibility buyers may want to consider. Browsing through information about various used car stereo head units gives shoppers an advantage in their search.
