Sorry - did a search but I guess this topic has MANY variants and I could not find a good answer.

So... I'm having my interior re-done in leather by C9. I'm using a pair of 944ts rear speaker panels (prefer the look) and my original (non hi-fi) front door panels.

I'd like to have C9 install new speakers (even though I don't listen to music in my cars) because it's a good time to do so. My question is, what speakers / sizes are the best (front/rear) options currently?

I'm not interested in any substantial modifications to enable fitment..!

Thanks in advance for any input.
