So is FI going to be selling AA stuff on their website sometime in the future.

Nope

So what does it mean that FI and AA are partnering up

FI and AA subs will built in the same build house, thats it.

AA has moved to a new warehouse in Las Vegas. We will be making all of the subs on the same assembly line as Fi... but each company is a distinct entity with no major parts sharing except for 1 magnet size, the standard basket/gasket combo, and terminals (oh and glue if you are really picky )

There is a decent line distinction between the two companies, and the business models couldnt be much more different either... dont think there will be too many toes stepped on between the companies.

Thanks,

Scott
