Whether you have a 1998 Pontiac Grand Prix SE, GT, or GTP, door speakers are all the same size. You can get a 6 x 9" which run for about $49.95, or a 5.25" which run alot cheaper 29.95. I got my speakers for a 1997 Grand Prix GT at Audio Express. You can order online at audioexpress.com. Hope this helps
For a 2000 Grand Prix GTP 4 dr, it's 22"
