Agree^^^^ That's where I put mine also. I think it's because th trunk is so big that you lose your sound before it hits the back of the trunk and bounces back forward. Even if you mount it on the right side at the rear of the trunk, speaker facing back, I think you'll still have ample amount of trunk area to fit your needs. Put, it where you are talking about and see how it sounds, then move it to the rear. Mount in the location that sounds better to you. JMO.
