I just put in 6.5s last weekend. The only spot of the pannelthat hits is the 10 o'clock position on the drivers door and the 2 o'clock on the passenger door. I installed hertz 6.5s and was able to fit the included grill on and snapped the pannel back on. When I removed it the only spots that had a small indent were the spots I listed. I removed the stock 5.25 mounting plastic held the speaker down and as far foward as it would go. I did drill holes but that was no biggie. Worked great. I do believe if you pop out the stock speaker grill in the door you wl see where you need to cut down. Just use like 4 or 5 of the pannel screws so its not so hard to take it on and off while modifying. But if your speakers came with grills you can do the same as I did with out modding only drilling a few holes. Good luck
