Hi, I have bought a B3 1.8S and am quite satisfied only I have no possibility to install reasonable boxes. I have at the moment ned really a lot of money and wanted to screw my existing boxes (202mm height 89mm) somewhere to use them in conjunction with the two 10s front. is the approach at all useful? if yes where should the old 20s pure, in the door? hut rack? I have no idea and would be in front of a advice or even an instruction thank you r. achja how difficult is it to retrofit a ignite plus yourself if you don’t really know what it is?
