I've heard good things about that hyper ground system. XS Engineering has them, and so far they have added 2-5HP/TQ on every car they've tried it on. The phase2 crew was talking about it when I was getting my wiring done, and they seemed to like it a lot, so Wayne said he was going to start carrying it because of what people have said about it.
I don't know if it has any impact on your speakers though.
