Solution for audio system in model A?

[DRG-ler]

Yes, now the topic is heading in the right direction.

@ Pete, yes, I already found these pictures here in the forum. Picture 1 shows the solution that I also prefer. However, at this point I am only planning a woofer / midrange that is covered by fabric. The tweeter should be mounted in the corners above the windscreen. I hope for a better illustration of stage.
This installation will be carried out by a car hifi specialist.

I don't like the rear speakers. Too obvious, I will completely do without them.

@ 5lugnuts

The space under the driver's seat is obvious at first glance. But if I think further now ... Are not the brake distributor shafts at this point under the floor? These can disturb?!?! I just don't know how much space there is for a speaker cabinet. It is also a question if the membrane is under the seat, whether dirt could collect there. All things that need to be considered.
It may not have to be an 8" or 10" either. Maybe a 6.5" is enough. I just have to see that I get a good chassis with a good efficiency, the frequency of which is as low as possible.

I was also considering maybe using the space under the back seat.

Kind regards
Andy
