What is with all of these subs having dual 2 ohm voice coils (i.e. stryke AV's, Adire Brahma's)...do they just expect everyone who gets them to get two? It seems very impractical and expensive too get 1200 watts in a 4 ohm load and almost all good amps now run safe at a 2 ohm load...it's just rather annoying for those of us not looking to buy two subwoofers.
