Upgrade for Sprinter van w906

Hey! I’ve a 2017 Sprinter van and looking to upgrade the sound system from the rubbish I have as standard. It’s a basic van with the oem A9069005103 (I think) head unit and standard speakers.

Head unit- I use Apple CarPlay and want a double din head unit , standard ish 6.5-7inch screen fine…have a old Sony xav-ax1000 in my other van and happy with that so nothing to much bells and whistles req or really expensive

Door speakers- I think there 5 inch? Ideally want a direct replacement size, no cutting of steel to fit but will do if say a 6 inch speaker kit that is really good required minimal mods for example.

Subwoofer- I want a 10/12 inch, I like strong bass/edm. Needs to be a slim enclosure to fit behind my driver seat up to the bulkhead. 175-200mm max depth, width upto 500mm, height fine up to 400mm Happy to go active, or separate amp and sub box…

BUDGET I’ve got about £1000 for this..less, brilliant 😊..Or, slightly more..if it’s worth it for certain components

I’m after..

Head unit Door speakers Sub/amp Cables

What do you guys recommend 👍🏼 Cheers
