suggestion also, buy na lang muna a powered sub. it will not take up much space, but dont expect the bass to be as good as big subs. parang tune-up sub lang. then change the front to DLS B6 for a better sounding front stage. this will cost you less than 15k. If not DLS may Intersys din na seps, and they also have a powered sub, will cost you around 10k for both. Try mo winterpine.
