6×8 Speakers – The Car Audio Guide

When it comes to choosing a set of 6×8 speakers, there are quite a few different options you need to consider. There are also many different brands to pick from, so how do you decide what will work best for you?

In this article we will be talking about some of the features you should look out for in a set of speakers, and then we will have a look at some of the best selling models currently available on the market.
Let’s kick things off by talking about what kind of speaker you should decide on.

Full range or Component Speakers?

The first major choice you will need to decide on is which kind of speaker you want to invest in. Full range speakers are the most common type of 6×8 car speakers you will find, and these come standard on most new cars. These types of speakers essentially hold all the parts in the speakers, such as the woofer and a tweeter. These typically come in two and three range varieties. The main difference between two way and three way speakers is that the three way types often have an additional component to process mid-range sound. This third component is often otherwise know as a supertweeter. Essentially this feature gives you better sound, so three way speakers are often the preferred choice if you are looking at getting some full range speakers.

If you are looking for excellent sound quality, then component speakers might be the best choice. These speakers work together with a separate woofer, tweeters and external crossovers to give you the best sound quality. Since these speakers are somewhat independent of the rest of the sound system, they are typically of higher build quality than most full range speakers. It also gives you the option of choosing your preferred woofers and tweeters to give you the ultimate custom sound system build.

There are advantages and disadvantages to each of the above 6×8 car speakers. Full range speakers are very easy to install, and are the quickest and easiest way to replace your standard sound system. Most decent full range sets will provide a good upgrade over the stock sound system.

Component speakers will give you the best sound quality, but installation can be quite difficult if you don’t know what you are doing as they come with many different connectors for example. There is also the added cost of the additional bits and pieces to consider, so this all adds up. It’s up to you to decide how much you are willing to spend, and if you are willing to do the installation yourself. Alternatively you can always pay a third party to do the install, but this can end up being a costly upgrade path.

What kind of power output do you need?

Next up you will need to consider the power output of the speakers. This is linked to your head unit or external amp, so you will need to find out what they can output. As an example, most head units can output 50watts (maximum output) per speaker. If that was the case with your car, then you should look for speakers that can handle 50watts. You must be careful to pay attention to the power handling RMS rating, and not the peak power handing rating. The RMS rating means the power which the speakers can continuously hold, so this is the important part to remember. The peak refers to the highest output the speakers can hold for a short period of time.

What sensitivity should you choose

The last thing to consider is the sensitivity of your speakers. Generally speaking, the sensitivity of a speaker will determine how much volume it puts out by using how much power. High sensitivity speakers need less power to operate, thus they are ideal for standard car sound systems. If you are simply using a head unit with full range speakers, then you will need to look for speakers with a high sensitivity range to get the best results.

If you are using an external amp, then low sensitivity speakers are a little better. The external amp will provide most of the power to operate them, thus the high sensitivity ratings aren’t needed that much.
Now let’s have a look at some of the top rated speakers currently on the market. If you aren’t looking at investing too much cash, then a good two way speaker set may be ideal.
