Suzuki Samurai Extension

Hello all of you, my father (me) bought a 13 year old samurai, I definitely want to do something about sound technology, but how!? In the car you have almost no space! The trunk is limited to about 15 cm deep, so NIX fits in! The series FS is a 13er in the footroom, probably widebands, since no HTs are installed! The biggest problem is that the 13er are located somewhere in the depths of the footroom, so you could use a lot of handicraft work. The doorboards are also not possible, because the door is so close to the seats, that you almost hit it there, and without DB which goes net, there is no depth! So the question, has someone ever done something about the car, or knows someone who can tell me where he has accommodated the FS meaningfully? Photos of the problem areas I can still post, but is at the moment nn bitl dark! Preislich habe i no idea yet, because it’s all about the general feasibility of the whole thing! Where to with the TMTs, the HTs and (probably impossible) nem Sub and the Amp! But you’ve already done so many things that seem impossible! 😉 So all the possibilities (how stupid they may sound) go here! Thanks Dennis
