What's the 2001 Ford f150 supercrew speaker size?

The 2001 Ford F-150 supercrew haS6 x 8" speakers that are found in the front and rear doors. There are aftermarket speakers that will fit directly into this spot, but the majority of speakers will need an adapter plate to work in Your truck. Upgrading the speakers in Your truck is the best way to improve the Audio quality. New speakers have better sound quality and tighter response than the ones that come from the factory. If You want even greater fidelity I recommend adding an amplifier to power them with a cleaner signal. Many people also change out their radio head unit to give even more control over the Audio.
