I'm considering replacing the factory amp with something like the Clarion XC1410. I know the factory amp lives in the passenger kick panel and I would love to be able to use that space for the new amp. Can anyone tell me, or point me to instructions for removing that kick panel without breaking it? I picked at it a little bit today and got the front part to pull loose, but the rear is overlapped by the (I guess you would call it) the passenger door threshold trim. Does that piece need to come off first?
