if you just want loud obnoxiuas bass....go with a kicker solo X.....if you want to get loud as can be and still sound good go with the W7 or RE MT. i feel your just triing to one up someone and say i have the loudest car in town. either that or i drank to much beer again....kinda known to do that.....but if you think the solo x will get as loud as the W7 and still sound good i will let you learn from that mistake!
Lol... Feeling the bass outside you're car will depend on more than what sub you're using. What kind of car its in, what box, will also have a huge part in it. Now, if you just want an all out spl sub, the RE MT, DD 9917, Eclipse TI pro Rockford TRF2212 will all do the job as well.
