One is that the lights on the Amp dont light up. The little stereo one or the red power light. How do I get to the bulbs to change them? Also on the Beovox 3000 speakers, on one speaker the tweeters do not work at all. If I plug another speaker into the connection for the BV2500 then you do get sound out so I presume that the crossover is ok. I know that if you plug BV2500 in to them it cuts out the speakers tweeters, is it possible for them to be stuck like that as I know that the original owner did have cubes with the system originally.</p> <p>&nbsp;</p><div style="clear:both;"></div>
