Today is the day I place my order and I'm trying to choose, I'm getting either 2 18 in Mayhem s,or soundqubed hdc4,I have an 03 Grand Marquis,with an X's power D 6500,220 amp alternator,and a synergy 35.1wfo amp.Which of these 2 subs will perform better? I want to feel the bass.My plans are to design my own box using the whole trunk.Thanks for any suggestions or comments.

I agree 100%. That's what I ended up going with and I love it. Unfortunately I've only got one 18" Mayhem, but it pounds! It's a beast! I see abother one in my near future!
