A set of 5 1/4" car speakers refers to a set of speakers that are of the particular size that is indicated. Whether you've had problems with blown car speaker systems in the past, or if you're looking to replace your current fuzzy car speakers with a set that has better sound, it's important to know what to avoid when you're searching for new speakers.
Things to Avoid
Avoid shoddily produced speaker systems. While this should go without saying, there are an unfortunate plethora of speakers not made to high enough standards. The best way to check on a speaker set that you're potentially interested in is to test them out at a car audio supply store. Most of these stores have systems set up for your preview.
Other Considerations
You'll also want to avoid speaker sets that try to condense all of the various ranges of sound into one or two speakers. The best audio systems will make use of distinctive speakers that are designed to play treble, bass and midrange settings. By putting all of these different frequencies into the same speaker or the same couple of speakers, you'll only distort the overall sound. Thereby lowering the total quality of the speaker set and the audio system.
Purchase a speaker set that has a warranty agreement, if possible. This will help to protect your investment should something happen to the speakers.
For more information, check in with a local car audio store or a specialist as well.
