6.5 Car Speakers Buying Guide
Every car will have some sort of speaker installed, which comes in various forms that include 6.5 speakers to subwoofers. Of course, they are not all the same as some OEM car speakers are far better than other cheaper manufacturers.
However, anything can be upgraded to your specification and knowing the right information can help with your buying decision. Within all of our car speaker recommendations above, we have included the following:
- Impedance (measured in ohms)
- Peak Power
- Frequency Range
- … and other feautres
To further improve your knowledge of car audio, we have have compiled all the details you need that will ensure you pick the right car speakers for sound quality and bass.
The range of the frequency determines the sound quality and how it is directed inside of your car. By adjusting the frequency of the speakers, you will be able to increase the effect of the sound. Tweeters function as a means of creating high directional and high-frequency sounds and if they are aimed at the correct angle, you will not have a good all round audio experience.
Using crossovers allows for an even distribution of the frequencies between the woofer and the tweeter. This results in power that isn’t wasted between the speakers because frequencies aren’t reproduced by units in the system that aren’t meant to handle those sounds.
These crossovers also include bi-amping which allows the system to have separate sound amplification for both the woofer and tweeter. This type of design is used for high-performance systems when they are installed.
Power Handling – RMS & Peak Power
When we discuss variables such as power handling, it refers to the amount of power that a speaker can handle. In terms of the difference, RMS (Root Mean Square) is the amount of continuous power the speaker can handle. Whereas Peak Power is the maximum power that the speaker can handle in short intervals.
In terms of peak power, this rating is usually achieved via a heavy hitting bass note and many manufacturers try to impress potential buyers with this rating. However, we strongly recommend that you base your buying decision upon the RMS rating, as this will provide a better indication of the quality of the speaker.
You may also want to invest into a quality car amp to ensure the RMS can be achieved for optimum sound quality. For further information, you can check out Sonic Electronix’s detailed comparison on RMS and peak power.
Impedance is the amount of resistance that the speaker has when when current and voltage is sent to it. Less resistance means more electrical signal will get through to the speaker. It is best to check the impedance range of a speaker when connecting it to an amplifier. Not all amplifiers are set to work with the same impedance when it comes to speakers.
Impedance is measured in “Ohm” but you may also see the symbol Ω when mentioned in the specification of a car speaker.
The measurement of speaker sensitivity concentrates on the amount of sound a speaker can yield when power is applied to the unit. Low power systems are ranked at a level that is 15 watts RMS per channel or lower.
These types of speakers do well with high sensitivity rankings that range in 90 dB. If your system is high powered, such as 16 watts RMS or higher, then you are going to need speakers with a low sensitivity rating.
The material that the speaker also plays an important part in the quality of the sound. Woofer materials are stiff yet lightweight in nature and are made from a synthetic material like polypropylene. Speakers with woven fabrics or metal coated synthetics are also used and can do well with a wide variation in temperature and moisture.
Tweeter materials are soft like poly, silk, or textile blends which makes the sound more refined sending out a mellow sound. Surround materials on woofers allows for free movement of the cone giving a much deeper bass sound. The material that is used is rubber based and provides excellent longevity, quality, and performance. Less expensive Surround Materials found on cheap car speakers include foam and cloth.
Connection and Cabling
Having the best car speakers, woofers, tweeters, and any other component won’t matter if the devices aren’t wired correctly. The flow of electricity throughout the unit must be even and balanced in order to avoid problems with the audio system.
Amplifiers function as a means to provide electrical pressure to a circuit. OHMS are used when measuring resistance against the electrical pressure of the audio system. Watts are used to check the range of how much power will be released. Voice coils are used to create the electrical resistance and perform the duties of the system.
Problems can happen when the amplifier provides more power to the system than needed because of incorrect impedance adjustments. This causes the amplifier to shut down because of overheating before burning out. Consider the range and output of the amplifier when attaching it to the system.
Consider the outcome of amplifier wiring options that will change the level of impedance because of the cross connection of multiple sub systems and voice coils. Use dual voice coils to increase wiring options when setting up an audio system. Use RMS ratings to determine the power output needed for the amplifier to attain adequate sound quality for the system.
How Do You Install Car Speakers?
Installing car speakers is not as easy as “plug-in and play”. For starters, you must be sure your current audio setup is able to work with the speakers as some have limited channels from the stereo or the amplifier is not able to cope.
To install car speakers, use the below steps:
- Check the dimensions of the speaker
- Disconnect the battery
- Remove the grill or door card
- Disconnect the old speaker from the harness
- Install the new harness and connect the speaker
- Test the speakers
- Put everything back together
This installation is a very basic setup and will follow closely to a straight OEM speaker replacement. However, many car audio enthusiasts may choose a custom setup for more bass and extra sound quality as per the image below. Follow this guide if you need a complete guide to installing the speakers.
What Size Car Audio Speakers Fits?
When you are deciding to install new speakers into your car, you need to make sure that they can fit. All the work will be for nothing if the speakers are not the correct size and you will have to cut into your door card in order to make them work.
The majority of car speakers are a standard size unless you go for something very custom. Below are some of the standard sizes for most car speakers:
- 6×9 car speakers – 6 x 9 inches
- 6.5 car speakers – Most common speaker at 6.5 inches
- Subwoofers – Between 8 and 15 inches
- Tweeters – Between 1 and 2 inches
Size and style play a large part when it comes to quality and sound in a car. The most popular upgrade is replacing the 6.5 speakers to a more powerful alternative for additional bass and sound quality.
Speakers come in a range of sizes and if you are willing to perform a little bit of DIY, the sound inside your car can be as crazy as you want. In terms of the DIY, it will involve a custom mounting bracket for the speaker and cutting into the door card.
Hopefully the detailed buying guide and car speaker recommendations will aid your buying decision in the correct way. Before you go straight into purchasing your new car speakers, you may want to be sure your double din head unit or single din head unit is able to support the speakers. Outputs at the back of many stereo systems are different and won’t allow for certain car speaker setups.
On top of this, your battery in your car may have an extra electrical draw from these speakers and you will want to ensure it is at its best.
