Could amp your components, or add a low frequency cut off capacitor to them, as the head unit would cope better then.
Amp the components, a cheap amp will make the components sound so much better than most head units, and run decent cables, especially the RCA cables, not pooty 2 sets from the car boot sale as i've seen done so many times.
How does a box give 20% more bass (base? lol) It may do by running the box smaller than the sub requires but this will eventually knacker the coil -- bad thing Also youd be best ditching the 2 ways in favour of a set of components 6.5" -- this allows you to split the mid and treble for better soundstage --- run direct of the headunit for now or you could amp up at a later date
