hmmmmmmmm, could do with having a listen to how it is now.
Your in danger that if you buy a sub, it may completly drown out the front speakers, and so all you get is bass.
Alternatively if you buy 6x9's they'll give you more treble and midrange, but won't they give you the punch of the sub.
decisions, decisions....
