Ford Expedition Speaker FAQ
What speakers should I replace first in my Ford Expedition to get the biggest sound improvement?
Start with the front door panel speakers. The Ford Expedition uses 6.5 inch midbass drivers in the front doors on newer configurations, and these tend to have the most impact on overall sound quality since they handle the bulk of the midrange frequencies you actually hear in conversation and vocals. On older configurations, the front doors use 6x8 inch full-range speakers instead. Either way, the front stage is almost always the priority. Rear door speakers matter too, but upgrading the front first tends to reveal a clearer, more focused soundstage. After the front doors, the 8 inch woofer in the rear side panel is worth considering since factory woofers in the Ford Expedition often struggle below around 60 Hz and lack meaningful output. Tweeters in the door panels or pillars can wait unless you notice a specific harshness or dullness in the high frequencies.
What size speakers fit the front door panels of the Ford Expedition?
It depends on the configuration. Newer Ford Expedition models use 6.5 inch midbass or full-range speakers in the front door panels. Older configurations use 6x8 inch full-range speakers in that same location. The 6x8 inch format is sometimes called 5x7 inch depending on the manufacturer, and many 6x8 inch adapters allow you to mount a standard 6.5 inch round speaker instead. That can be a useful approach if you want more aftermarket options. Measure the mounting depth carefully before buying. Some Ford Expedition door cavities are shallow enough that extended-basket speakers or those with large magnets may not fit without a spacer ring.
Does the Ford Expedition have tweeters, and where are they located?
Yes, several Ford Expedition configurations include tweeters in multiple locations. The A-pillar position uses a 0.75 inch tweeter. The front door panel on some configurations includes a 1.5 inch tweeter, and the rear door panel uses a 1 inch tweeter. These are relatively small drivers and tend to handle frequencies above roughly 3,500 Hz to 5,000 Hz depending on the crossover point the head unit or amplifier uses. Replacing factory tweeters with aftermarket silk dome or aluminum dome tweeters can sometimes improve high-frequency detail, though the improvement may be subtle if the rest of the system has not been upgraded. The A-pillar 0.75 inch location is fairly restrictive in terms of what will physically fit there.
