fits in the itty bitty hole in a 93 civic if that answeres the question not sure if the hold down still fits might be a little taller than the stock battery but I know it fits in there so I would guess so I mean my civic is a step up from a lawn mower battery.
Personaly I am going to go with powermaster though jegs has them for 260 shipped and they make have a higher ca and faster discharge rate if I am not mistaken
I have seen 1400's in those cars, but I dont know if they changed brackets to make it fit or not. One of the best systems I seen and heard had 1 up front and a 600 by each amp.
