4" Speakers Information

4 Inch Car Speakers
Upgrading your car speakers is the best and most affordable way to improve your sound system. An after-market set of speakers is better able to handle a wider range of frequencies, giving the lower notes greater depth and making the higher notes sound more defined. After-market car speakers are built with materials that are durable and temperature resistant.

4" speakers are found in many types of vehicles. They typically are used on the dashboard, in the doors, or the rear deck below the rear window. It is common for 4" speakers to be used in outdoor applications such as marine or power sport vehicles. These speakers can also be found as a 4 inch speaker component system. Make sure to check out the popular brands we carry such as Pioneer, Kenwood, Alpine, JVC and more!
