hi all, I’m very new here. I’ve just bagged myself a Leon FR estate and instantly feel the need to fit a subwoofer. Would anyone be kind enough to share experiences with power cable routing and also hi-low converter wires ie where’s best to splice into the rear speaker wires and what colour wires to splice! Thanks in advance. Oh and if anyone knows one of them cool vagcom guys in Coventry hook me up with their details!
