In the automotive aftermarket, one of the most upgraded items in any car is the stereo. Car owners of all ages often choose to upgrade their stereo first. The first step in upgrading the stereo is changing out the head unit or deck. The head unit is the control center for the entire stereo system and is the piece of the equipment the driver uses to control the system. There are many options and add-on accessories you can add to any head unit and it is good to consider which of these you may be interested in prior to purchasing the head unit.

A RCA pre-out is a jack on the back of a head unit that allows you to connect signal cables or RCA cables to, to transfer the sound from the head unit to the amplifier. The number of RCA pre-outs your new radio will have is an important feature to look for. Many high end radios will have 3 pre-outs: one for a front stage amplifier, one for rear stage amplifier and one specified for a subwoofer amplifier. If you plan on building an extensive stereo and using a 4 channel amplifier for your mid-range and high sound, 3 pre-outs is the only
way to go. It will allow you to be more adjustable and make tuning the amplifiers a breeze.

Having the ability to adjust the level of the subwoofer amplifier through the radio is a feature many desire. This allows you to slightly change the gain of the amp through the radio, preventing you from having to get in the trunk or where your amplifier is located to adjust it. If you desire this feature, select a radio that has a subwoofer level control, which can be signified by a seperate RCA pre-out labeled subwoofer.

In today’s music world, everything revolves around one thing: the Ipod or MP3 player. Many consumers in the market for a new radio are simply looking for one that will allow you to play an Ipod or MP3 player through

Another option for listening to your MP3′s or portable music on your car stereo is a USB connection. Some radios will have a plug on the back while some will have a jack on the front of the radio. You can load a lot of music on a small zip drive and then just plug it in and go.

An HD tuner allows your radio to pick up high definition versions of local radio channels. The programming is generally the same, you just get a higher quality signal.

Many drivers today use satellite radio as their primary source of listening pleasure. These subscription services feature commercial free music channels and censor free talk radio. Not to mention if you have an HD radio your subscription is also free. Which is always good!
