i've just brought 1 of the new vibe evo series 12" subs and have wired it all up... running smoothly and sounds amazing! however, one of the features of the sub is that it has a UV light emmitting from the turbo port when in use but this remains on even after the head unit is turned off which was running my battery down until i disconected the power cable. think this might be someting to do with the rca wire but cant see any cuts or anything in the cable and the connections have been double checked.
