Lawrence, if you run the 6x's in series, you won't be driving them off the amp after the first pair. You'll be driving them off the preceding pair which is not an ideal output impedence and is constantly fluctuating. Not a good idea. Is this for home or car use?
heh, well it was like i was in a sweetshop when i had the idea of building me own speakers. ive come to the conclusion its too much hard work doing it from scratch when ye know nothing about it so i gonna get meself a pre-configured kit that the shop has put together so i cant fail.
