Hello dear Renault fans, I have bought a Renault Megane RS 250 CUP. Unfortunately, this one has only one standard system. I still have a power amplifier, a subwoofer and the necessary accessories from my old vehicle. I would have built this system already long ago, but I don’t know how best to get from the car battery into the interior without drilling etc. I’ve already searched the inet but found nothing suitable. I hope that one of you will find a good solution g has ready! Thanks in advance 😉
