The speakers are available in a wide range of sizes and are constructed from high quality materials like polypropylene cones, durable rubber surrounds and 1/2" or larger PEI dome tweeters.

I only have about 3/8" where part of the speaker meets the dash.** A: My application for my Toyota Solara was quite different and difficult, having to drill new mounting holes, etc. plus I reused the stock grills that were already on the rear deck. Sorry **Q: would these fit an 83' Ford Ranger?** A: Does the pope help child molesters get away with their crimes? The answer is YES **Q: What is the mounting hole distances< (diagonal and across)?** A: chris u.; chris t. here. sorry about delay in answering question, had to find time to pull car panel off to measure. these speakers from across the edge, the holes are 3-1/8" center to center of hole. diagonally across the 'face' of the speaker the holes are spaced 4-1/2". the holes are not round, but slotted; with the slots diagonal in towards the center of the speaker. hope this helps. **Q: Will these fit in my 2001 jeep grand chetokee** A: The 4" will be too small for your jeep, do a google search to verify what size you need. From my search results, your year of jeep uses both rectangular (6x9) and circular (6-3/4") speakers in the doors. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Love them *by on Reviewed in the United States 7 January 2021* Not really an audiophile, just like tunes when driving.
