Contemplating buying an Ampeg SVT 810 and had a couple of questions... 1. Can an Ampeg V-4BH be used with it? I've seen old 70s V-4B's used with 2 8x10s (!), but I've heard things about underpowering cabs and wanted some confirmation. 2. Can the 8x10 fit into a 93 Chevy Cavalier? Haha, weird question, I know. Just wondering if it'll fit into the backseat, maybe. How about most 4 door cars? What if the car has a folding back seat allowing it to rest lengthwise through the backseat and trunk? Thanks in advance.
