Signal-To-Noise Radio: This can measure how well the radio lessens noise from the background. Higher ratings mean less noise.

RMS Power Output: RMS Power Output is the place where the amplifier produces continuous power. Power is measured in watts. If the RMS is higher, the music coming out from the speaker will be louder. However, we can not say that the higher the RMS is, the clearer the sound is. Use the RMS number in comparison with various amplifiers and receivers.

RMS Power Bandwidth: It is the frequency response which is used to determine the RMS power rating of the built-in amplifier. The best range is 20-20,000 Hz.

Peak Output: Peak power is measured during a brief musical burst.

FM Sensitivity: It can tell you how well the receiver picks up a FM signal.

Preamp Outputs: Number of RCA jacks on the back of the receiver.

Preamp Voltage: Plan to mount an external power amplifier? Then you are advised to opt for the unit with higher preamplifier voltage, as it allows the amplifier to produce its maximum output.

Sources mean where the music or sound come from as we mentioned above, such as iPod support, MP3 playback, DVD playback, internal hard drive storage, GPS navigation and so on.

AM/FM Radio: No matter where you are, a digital radio tuner is able to pick up free local radio stations for you.

Satellite Radio: Choose stereo which is labeled "satellite radio-ready", if you want to listen to satellite radio. Some stereos have compatibility with radios from XM or SIRIUS, while some only function with one or the other.

You have two choices of the HD radio, one is a built - in unit and the other is external, which can mean an added feature to an outside part.

Audio CDs: Whenever people listen to the music from the CD player, no one wants to bear any noises if possible. In this situation, you have to take the CD signal-to-noise ratio into consideration. The higher the rating is, the cleaner CD playback will sound.

DVD playback: with the DVD playback of the stereo, you have access to the DVD playback. Make sure that you have a monitor or pop-out screen attached to the unit if you would like to have video playback.

iPod Music: when the stereo is compatible with the iPod adapter, you can not only listen to the music of high quality stored in the iPod, but also charge the battery of iPod via the stereo.
MP3/WMA disc playback: A CD player which accepts MP3 or WMA discs enable you to listen to 10 hours of music on a single disc.

Sound Control

If you aim to have better sound of the music, then the stereo with treble, bass, and midrange control would be your best choice. However, if you have the desire to experiment with the sound, a model coming with features like DSP or digital time correction would suit you.
