I don't want to remove door panels to look as I hear the clips break so I would rather have new speakers on hand and remove it only once.
I replaced all the mid range speakers with Eton Co-axial tweeter versions as a temporary measure pending a full DSP/amp install…I was very pleased with the incremental improvements….this was on a 677..but a 676 had similar impact.

Audio is such a personal thing so I thought effort spent / money spent performance gained equation was positive…

With a few trim tools it’s pretty straightforward to pop the door skins off..remember to take all the screws out first which as in different locations on both doors..

For the doors best to get a set with the separate tweeters as they impact the spatial image and ‘tone’ or ‘colour’ of the sound quite a lot..

FWIW updating the woofers in the footwells has a big impact but that’s a bit harder work..
