You can start by writing like a normal human being and cut the ebonics! You do know that your on the clubcivic forum right? I don't understand why you would take the time to join this forum if all your going to do is trash the car that you and others alike drive. (You do know Honda's are japanese right?) As for your advice being taken... you've proven to nobody here so far of what you supposedly know. If I told you to put antifreeze in your gas tank because it makes the car go faster would you do it? What if I told you I was a mechanical engineer, would you do it then? Are you just supposed to take my word just like that because I told you to? The human race has evolved to the point of where individuals can draw there own conclusions without the help of 18 year olds claiming to be gurus with nothing to back it up. Unlike you, I can back up the following:
Sealed enclosures will provide a more linear response throughout the bass frequencies, they are also quicker in attack due to the trapped air in the box acting as a acoustical suspension system. This is also why they are preferred by people with sound quality setups.
Ported enclosures need to be built exceptionally well and not messed with by the average DIY. Even the slightest miscalculation in port length and diameter can induce huffing/port noise. Ported boxes will play exceptionally well at the frequency they were designed for but at the risk of sounding sloppy or slow. They will also not play that well into the sub-sonics.
Bandpass enclosures are tricky to build asides from being huge. Bandpass enclosures will do exactly what the word implies: "A band-pass filter is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range" They will work very well at producing bass at given frequencies and can play very low but are without a doubt the slowest in terms of response.

Oh yeah, I also noticed you live in ontario. Please stop by quebec so I can knock your punkass out. Enjoy your short lived stay on Clubcivic and have a good day!
that's a VERY big plus, since my amps and caps are in the trunk, too. 
i think i'd just read reviews, speak to people i know, etc.
