3.5" speakers are often used up in the corners of the dash of your vehicle. We offer 3.5" speakers from Rockford Fosgate, Kicker, JL Audio, JBL and Infinity. These speakers are mostly designed to give you high and upper mid response due to the size of the speaker. It is important to match the RMS rating of your speakers to your stereo or amplifier. Also, make sure to note the tweeter protrusion on the 3.5" speakers you are looking at as it can cause an issue with mounting in some cars.
