erm...i always wonder how come they say can direct connect to sub..btw, maybe they mean active sub? i was wondering too and wanna get the answer...consider the hu provide 52x4 pmpo is about <20 rms each..if they able to bridge, then it become like say 60rms...but any sub that had such low rms? erm...8" chap ayam?

even it's 8" it will be very hard to drive it...unless the 8" is those really old school paper cone sub with no rubber / foam surround...

most probably mosfet / amp transistor..if mosfat, then can get new player if ur play cost <400...change mosfet priced RM200 for pioneer..othe i not sure..but if amp transistor, cost<50..lolz..if by me <30..hahaha
