I've got the standard speakers, but I also have an aftermarket head unit (10yo Pioneer) and amp. I get pretty good bass out of the standard speakers. It's the system that is less than optimal (at least with the standard system).

If you want upgrades, the man to talk to is Rod Birch from Car Audio Innovations. https://www.caraudioinnovations.com/ He's been doing stereos (and specializing in Porsches) for at least 25 years. He used to be very action on Rennlist back when it was via email and run by the guy, John Dunkle, I think.

The usual issue that comes up with speakers is that the foam disintegrates and they start to rattle. I've had that happen to both large door speakers, and now the pass' mid-range speaker is rattling.

I get decent sound out of the stock speakers, but I believe that's because I've got the aftermarket head unit and amp.
