Hi together ! I would like to install a subwoofer with my Peugeot 206. The car radio (JVC-KD-X220E) plus front boxes were already installed during the car purchase. Because Subwoofer in the trunk has unfortunately been removed by the dealer. Therefore remain in the trunk Cinch cable (red+black+radio cable?) As well as the 2 cables from the car battery. I already own a new subwoofer, a JVC CS-BS-120 1300W/150W RMS. Must only be installed. Now to my questions it plays a R What am I going to buy for an amplifier? And what should a suitable one cost for it? Do I have to install more cables or something like that? I hope that I have mentioned all the important information. Thank you in advance!
