I have had a 12" for a while, and swapped it for a 10" that left some more room for everyday use. Driving it with 200W. Not nearly enough to have the mirror drop off. Plans are to go for 1 (vented) or 2 (sealed) in the below idea (the orange part being the baffle, the space below will be the enclosure (so I loose the cargospace there), carpetted so you won't even see it is there and the boot can be used as normal), but then of off 420Wrms (single Aliante LTD, 500Wrms) or 800Wrms (double Aliante 2x350Wrms). But that may not happen until way in 2018... Time is in short supply.
