If I'm understanding your question correctly, the answer is YES. The '02 SE 6 disc radio easly swaps out with the '02 XE radio. How do I know you ask. I did it myself in about five minutes. You will, however, need to hook up an amp with speaker level inputs to replace the RF amp that comes with the SE radio. If you hook up the radio w/o the amp, there is barely enough power (about half the volume as the stock XE radio). I suppose they didn't need to have a high output out of the SE radio since it was going to be used with the RF amp anyway, therefore the low volume.
Good luck an let me know if you need anymore info.
