I would need to see the back of the speaker, can you pop it out of the box and get a pic of it?

The 10's I have are Power Acoustik FUBR's (not FUBAR's) just metered them Saturday at Toby's, 130.1 in a sealed box in the back of a Cadillac. In your hatch they would meter higher (no Cadillac barrier wall, lol).
