Do I have to remove the door panel to replace the radio speakers in my 99 Ext Cab Silverado? Or is there a way to remove the large grill and not remove the panel? Tks in advance..

You need to remove the door panel.

and disassemble speaker out of its mount. they did very good job making it as aftermarket speakers unfriendly as possible. speaker is attached (bonded) to a large plastic ring that clips into the speaker mount. brace yourslef up - i am very strong and i had hardest time ever unclipping and ripping that speaker out.

if it makes khrr noises, try what i did - i packed fiberglass insulation between diffusor and the metal frame. took care of it on both sides.

Thanks. I bit the bullett and took the door panel off. It was not difficult as I learned from another site how to.. I replaced the original (very low cost paper ones) speakers with a couple of better speakers I bought at Wally World. I couldn't use the original rubber mount so I drilled new holes and screwed the new 6.5 inch speakers into place in the original hole. it worked just fine. Both speakers were blown.. Thanks for the two responses..
