I bought a pair of Pioneer TS-A6870R 6x8 3-way speakers for the front of my 2003 P5 and they fit perfectly. It doesnt list the protege as a a fit on the box, but they are a bolt on replacement for our stock speakers. The rain guards will fit perfectly as well, no cutting required. They are rated at 50w RMS each. Freq range 30-28k hz, 91db sensitivity. I got mine at walmart for 60 bux after tax. Huge SQ improvement over the siht stock speakers.
