## Questions & Answers

**Q: What is the dimension of the speaker face from the mounting surface? 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.
