Depends... Like how much bass you want
in your music. How much power you want
to push..
I have the four banger and its enough for what
I need. I listen to alot of Hiphop/Rap music
and it is sufficent for what I want.
It is not on the level of a large woofer though.
I'm sure a single 12 or 15" would be even
better. But you would need either a custom box
or a ready made box that just sits in the back....
Mine is great for what I want. The midgate is functional
when I want to use it I just take it out from behind the seats.
Its functional and pratical.
Check out the "Fourbanger numbers finally" thread in the
A/V section. That will give you a good idea of the amount
of bass that they put out.
Also you may want to ask to hear someone's system at
a GTG or something. That will really be good because then
you can look at the quality while listening to the bass...
Hope this helps
