Hello everyone, I would like to make new boxes in my Lupo in the doors. Which ones are recommended? What does one need for a diameter and what maximum installation depth? What do I have to pay attention to when buying (ohm or power) so that it also sounds good? I have a radio with 4* 35 watts! I would prefer boxes with the maximum bass in this class! Thanks a lot Gruss Dave PS: doesn’t know about you with the gear oil? Have no answer for a week!
