Has anyone else besides me noticed that the '02 xterra front speakers are permanently integrated into the door spacer? I had an '02 Frontier that I traded in on the '02 xterra. When I went to put my aftermarket speakers from the Frontier into the Xterra, I discovered that the Spacer can't be removed from the speaker! I guess that this is an attempt to speed up assembly line process. I'm going to have to purchase an '01 door spacer to install my old speakers. On the bright side, the speakers that are installed appear to be of pretty good quality. They appear to be polypropylene with butyl rubber surrounds. The woofers are rated at 2 ohms, i suppose to get the most power from the head unit. That means when i replace them with my aftermarket 4 ohm JL Audio's, that I'm going to lose about 3db in output. I hope that will be enough to get me by until I drag up the energy to install my amp.
