What to Consider when Purchasing Best 6.5 Car Speakers

  • Power Handling – When scouring through your options, you’ll want to inspect the speaker’s power handling ratings. Yes, two figures are frequently utilized to describe the speaker’s power capabilities. One is the peak figure and the second number will be the RMS rating. The former will tell you precisely how much power the speaker can handle at any point in time.The RMS describes the amount of continuous power the speaker is capable of handling. Generally, the RMS rating is considered to be a little more important than its counterpart.
  • Frequency Range – This figure is important, but not as much as the aforementioned factor. As the name suggests, the frequency range equates to the specific frequency range that the speaker is compatible with. A wider range will help to make the speaker much more versatile.
  • Sensitivity – Truly, sensitivity and power handle go hand-in-hand. A great amount of sensitivity will allow the speaker to utilize less power to deliver the quality of sound that is desired.
  • Size – Vehicles are limited in terms of size. Suffice to say, you’ll be able to fit a much bigger and more comprehensive stereo system in your home than your vehicle. With this in mind, you’ll need to be much more strategic, when selecting your speakers. The size will be crucial. Making a wrong choice could very well result in you having the inability to fit the speakers into your trunk, backseat or wherever else you wish them to go.

Finally, it is pertinent to remember that you’ll have two basic options. You can opt for component speakers or full-range speakers. Although they’ll serve the same purpose, they’re immensely different. Below, you’ll learn the basics of both.

  • Component Speakers – If you opt for component speakers, you’ll achieve a better sound quality. However, you’ll need to work a little more diligently, in order to pick and choose the right equipment. With component speakers, you’ll need a different speaker for each frequency range. Tweeters are designed for the highest frequencies, while woofers are suitable for the lowest. And, mid-range speakers are compatible with everything in the middle.
  • Full Range Speakers – Full-range speakers are often referred to as coaxial speakers. The speakers are designed to be able to handle a wide range of frequencies and help to eliminate the need for multiple speakers. Although they’re more convenient and will give you the ability to assemble your vehicle speaker system more rapidly, full-range speakers aren’t capable of matching the audio quality of the aforementioned alternatives.
