Kid across the street has an 03 eclipse. It was all we could do to get a 2.0 @32 htz enclosure in the rear hatch area with an XFL 12.Sub Rear Ported rear@ approx 9 inches. to keep the use of the back seats. Cant imagine trying to sardine in a pair of 15s back there,even with the seats down for proper enclosure needs t serve any justice. A pair of decent 1 k tens will surfice
