Well for the final touches I had to install 2 crossovers. And joined them to the 2 speakon connectors (subwoofer) on the side of the case. Well now it's really full in there, but it still has enough place for airflow (in through the former pc powersupply outlet and out throgh the top where the old speaker used to sit). The other 2 connectors are for being able to run it of an external battery pack (12 Volt 18Ah) which you get from car jumpstarter. I also put 2 chinch connectors to the front to be able to attach a mp3 player. The player and the cable tucks away nicely in the in the pocket when closing the lid.
Well and that�´s it. Took me about 4 Month to finish it all together. Hope to give you some inspiration for your projects. Some more stuff on my side, that still needs documentation:
