Nothing's changed really. Had my MOT a couple of days ago, and failed miserably. The list included a new tyre, welding to the sills and seat belt mount, washer jets, broken light reflector, broken indicator (was working that morning), broken light fittings, bad light balancing, new windscreen (crack), and they managed to half kill my amp/sub by checking under my false boot floor. Have now got really bad buzzing from somewhere and I can't work it out - It wasn't there before. The RCA connections on the amp seem really loose though and do make a difference to the buzzing.
