i am thinking about changing the stock ML sub in the 04 SC430 that I have. I would like to know if any of the aftermarket subs will fit in the space where the stock one is. Essentially what I would like to you is swap the subs. The question is... is it worth it? will it give me more bass or am I just wasting time/money?

Any input would be appreciated.

I know someone else installed something in their useless back seats, however I am trying to avoid that option. Additionally, the installers at Sound Advice told me that they'll be able to install something in the trunk, but that chances are it won't be any lounder than the stock system (I don't know if I believe them). Regardless, any input as to what I might do, or pictures of what you guys have done would be greatly appreciated.
