I used to cram my 4x10, 1x15, bass in hard case, guitar stand, 4 space rack mount and accessory case about the size of a 6 space rack mount case (before I broke into the wonderful world of pedal boards....) all in the back of my 91' civic. Back seat folded down of course. I could still see out the rear window and had room to spare for drummers extra stuff he couldn't fit, or guitards stuff when he was out of a car. Front seat always open for a groupie or the guitard...
