Speakers are constantly changing as technology improves, and speaker sizes are not static over time. This means that when you need to replace a speaker setup, you might find that you can’t get the same size speakers that were originally installed in your system. You might not even want to have the same size speakers since the performance of speakers can change so much over time.
6.5 speakers can fit in 6.75 spaces. It has become so common to change your speakers for other sizes that there are lots of great aftermarket workarounds to make this work out really easily. You should be able to get aftermarket brackets and face plates to make the speakers work in 6.75. You can easily make some modifications to your setup with creative support behind the speaker to make sure that things work as they should.
Will You Need to Modify 6.5 to Fit?
Because of the size difference between 6.5 speakers and 6.75 space, you should not need to make any modifications. You should be able to just bolt in the speakers, and then use an adapter plate to mount it. Some people find that there needs to be a filler solution behind the speaker to help with vibrations and other kinds of problems.
Always test out the speakers before you consider that your speaker solution has worked out. It can be common for vibrations to make your sound quality less than ideal unless you do the right added support for your installation. Many people don’t realize that it’s a good idea to test out your sound quality and end up unhappy with what their speaker solution offers them. Being sure that you have checked out what your speakers are working like before you wrap up the installation is a good idea.
There will always be some forms of modification that are needed to make 6.5 work in a 6.75 slot, but it is not usually difficult to make this kind of fit work out.

You can find a lot of aftermarket options that will make it simple to ensure that your speakers work the way they should.
