happy, i strongly advise against getting an active sub. sayang lang pera mo. trust me, i have been tweaking my car stereo for the past ten years. even if you get the cheapest amp and sub combo, it will sound much better than an amplified sub.

the main market of the amplified sub is in first world countries where labor and installation is very expensive. so ito ang do it yourself solution. eh, dito sa pina, mura lang ang labor and install, go for the separte amp and sub na lang.
