I am looking for a 10" or 12" sub...sounds easy enough, but it needs to be freeair or a Small box <1.0 cu. It will be going in an IS300.
I do not have an aftermarket deck, so I will get my signal from the rear speakers...leaving me little to no adjustment from the drivers seat.
The amp will most likely be a Phoenix Gold. (Or another amp that will run a remote gain control to the drivers seat)
I had the Shiva in the SVT, but the current box leaves me with about 6" of trunk space.
Give your suggestions.
