Are there any affordable and good loudspeakers to replace the front two?

How can I solve the loudspeaker problem with the T5EVO? When listening to music, either the front has sound, or if adjusted, only the rear seats have sound. How can I set it so all loudspeakers work? There are 6 loudspeakers, but it feels like only the front two are working. [Crying][Crying]

I would like to ask if there are pre-installed wires for adding loudspeakers in the rear two doors?

Are there any affordable 20-inch tires that fit the 718T? Specifically, front 235/35R20 and rear 265/35R20? I can't afford PS4 and PZ4 anymore.

I only replaced the front two tires, not the rear ones, and they're from two different brands. The tread patterns are quite different, and the load capacity and speed ratings aren't the same. Is this okay? Is there any risk? Do I need to replace the rear tires as well?

Why does my 2014 Touran only have either the front two loudspeakers or the rear two loudspeakers working at the same time? I can't find how to set all the loudspeakers to work together. Can anyone help with this?

Guys, should I replace the tire if it has cracks? Any good tire recommendations? Thanks.
