When you’re putting together a system, the three most important components are going to be your signal source, speakers (including subwoofers), and power source. These three elements work together to determine what your system ultimately sounds like.
The Signal Source
An in-dash player is the heart (or brain) of your sound system-it plays your music and sends signals out to the speakers.
What to look for
Music formats: Most units sold these days play regular CDs, and many will play MP3s that you’ve burned yourself. Others are satellite radio-ready or have CD changer controls. Think about how you listen to music and get the one that’s right for you.
Dedicated amplifier preamp outputs: These plugs on the back of the player send your music directly to an amplifier. If you plan on adding a subwoofer you’ll need at least one set of preamp outs, more if you plan on adding multiple amps. Look for 4V or higher outputs-they’ll send a cleaner, more powerful signal to your amp.
Subwoofer fader: This dedicated fader lets you control the volume of your subwoofer(s) directly from the in-dash player in case you need to take it down (or turn it up) a notch.
Movies and navigation: Some in-dash players let you watch your favorite DVDs, perfect for family vacations. You can even get a unit with built-in GPS navigation, so you never have to stop for directions again. Continue Reading
