Subwoofer weights

[nicknick]

The 370z has 2 subwoofers, at least it does here is Australia. As far as I know these things can get pretty heavy. I wonder how much they weigh and does the Zed really need two subwoofers? how much weight can be removed if it only had one, which for me would be ok. I mean the Zed is a sports car comparable to the Cayman which has similar features but weighs significantly less, if Nissan could strip the Zed of "unnecassary" weight, his car would be a killer. Don't get me wrong i'd rather have a Zed over a cayman anyday for many reasons, but just imagine if the Zed weighed 100kilos less. It couldn't be that hard to do right?
