So, I picked up a 2002 EV to use as a shop van. Great shape for that intended use, has an upgraded head unit (good enough for me), and new speakers on the way from Crutchfield. However, I would like to install a small subwoofer, but not like to take up too much space.
I put one of those low profile ones in my E250 that Vanagon guys put under the front seats, but I don't think they will fit under the EV seat bases. I could build one inside the seat base as an enclosure, but I'm looking for quick and easy here. Think 'better' sound, not 'awesome' sound.
My other passing thought was to bolt it to the back of the front passenger seat base, but not sure about that. With swivels, it might get in the way.
