Door Speaker Help!

Hi all I just replaced my stock door speakers with Kicker 46CSC54 speakers. The car is a 2004 and I'm 99% sure I have the option 490 Hi-Fi sound system as I have the door speakers and an amp. I'm pretty sure I don't have the Bose system but the sticker with my option codes is so faded its unreadable. I know for sure I don't have the base system The new Kicker speakers are 4ohm, 75W RMS, 225W max. When I pulled the stock speakers out, they said 4ohm on the back and there was a sticker on the housing that stays on the door that said 70W so once again I'm pretty sure they should work. Once I installed them (just pulled the old speakers out and put the new ones on using the same connectors) there was no sound at all at low volumes and at high volume (25ish) they would just crackle whenever there was bass in the song. I'm just confused at why they aren't working at all, If the install wasn't so simple id assume user error. Again, since the install was so easy, I didn't bother to test before putting the door cards back on so once I figure it out, I'm going to have to do it all over again. Also, my left side stock speaker didn't work at all before I replaced it and still doesn't, I didn't see any obvious signs of failure, but it was also dark and cold, so I didn't spend a ton of time looking. The entire sound system is completely stock, and I seem to be learning the head units tend to crap out after a while. I'll attach some photos along with the post.

I was going to replace the speakers in my 1998 986 boxster but i decided not to after doing some research.

Apparently the door speakers are not regular speakers but sub woofers only. And the dash speakers are soldered in place without traditional speaker connections.

After looking into it I realized that it was a can of worms that would probably only work with original porsche speaker replacements which was going to blow the budget.

Pianoporsche is pointing you in the right direction. I have a 2000 Boxster, and the audio system in your car has a slightly different configuration. However, I think one similarity is that the door speakers are not full range speakers. They are not subwoofers, but they do emphasize the lower frequency sound. The amp in your front trunk only feeds low-frequency sound to the speakers. That's why you are not achieving the results you expected when you changed the speakers.

This thread https://986forum.com/forums/boxster-general-discussions/79558-door-speaker-recommendations.html has some useful information about the door speakers.

I installed some low-range speakers in my doors and powered them with a small separate amp that receives a signal from the subwoofer output from my aftermarket head unit. I did have some issues with the installation because I wanted to use larger speakers. It took more time and effort than I expected, but I'm pleased with the improvement in the sound.

Good luck.

The dash speakers have some non-standard mounting but I have a '98 and was able to remove the speakers, unplug the wires and replace the surround foam.
