I picked up one of those 1500 watt Power Inverters from Costco today for $85. The dimensions of the unit are roughly 14"x6"x3" Now the question is where to put it. The drivers side rear corner has the subwoofer, the passenger side rear has the AC unit. I thought about putting it under the front seats but I would have to remove the blower for AC on the drivers side. The passenger side has a box, possibly the ECU, that I'd rather not relocate because of wiring issues. The only other place I could put it is in that long storage panel in the passenger side rear. Or may go back and exchange it for the smaller unit.
