What Size Speakers Fit in My Car?

You are finally going to break down and upgrade that car stereo system you have. You might even still have the factory installed one. If so, then there are some key points you need to know before you head off to the store. One of the most important questions will be: What size speakers fit in my car? Let's see if we can figure out how to tell this.

For starters, you can check the manuals. The speaker size is sometimes listed in there, along with a part number for replacement. We do not need the replacement numbers, just the size of the actual speaker you are going to replace. If it is not there, then you head to the next step.

You can always just measure them. They are going to be in the doors, or in the flat section behind the back seat, just below the back windshield. You need to access these back ones from the trunk. Most of the time, these are going to be 6x9's, but they could still be a different size. You should need a screwdriver and tape measure for this.

Remove the cover for the speaker and measure the diameter. This will give you a certain number. For example, you might have a 5" speaker in each door, and 2 6x9's in the back. If you are having a hard time doing this, or are not real sure, then just ask the guy at the car stereo place. He will be more than happy to help you out with the speaker sizes.

Now, just because you have a standard size in the car, does not mean you need to stick with it. These professional car installers can make the holes bigger to accommodate bigger speakers. There will still be a certain amount of air space required behind the speaker to get the full sound quality. They can help with this as well.

One last thing is if you want sub-woofers. This is where the bass part of the songs will come from. Most people install these in their trunk in a speaker box. As I stated earlier, certain speaker sizes require a certain amount of cubic in of space to sound their best. There are 2 things to consider here: how much room you actually have in your trunk for this, and what size speakers you want.

If you base this decision on the trunk space, then this will give you a maximum box size, which will then place you in a certain speaker size. Once again, professional car stereo installers have a ton of knowledge in this, and will tell you how big the box needs to be, and what size speaker will go into it. Plus, they will just build it for you, and install it. What could be easier?

If you are trying to find out what size speaker fits in your car, those are the basic options you have to do this yourself. Please, do not be ashamed to ask for help on this. The last thing you want is to spend the money on a good set of speakers, and put them in the wrong location. This will end up not sounding good, plus you will have wasted your money. Get the right speakers for the right job and you will be definitely happy.
