Car Audio Install: Golf 4 Variant Double Subwoofer

Hello everyone.
Here's a suggestion/guide on how to install a car audio system and a double battery tray in a Golf4 Variant.
The basic concept is certainly transferable to other vehicles as well.
Unten schon mal ein paar Beispielbilder für den 1. Impression.
Best regards,

Wouldn't there have been space for the capacitor and the amplifier in the lower left corner, underneath the fixed part?
Or is that just because of the "show and shine" aspect?

Hello Turbinchen.
Yes, a little bit of "show and shine" definitely needs to be included in the family car .

Do you mean underneath the small section of the cargo floor?
The space is not sufficient (at least not for both).
Furthermore, the component must be removable so that, if necessary, the carpet underneath can be removed and the metal cover over the spare tire can be opened.
Best regards, Kevin.
