i heard that when you get a new video system you can't use ur factory sub and amp. is that true? and which in dash dvd video system do you prefer? than

its not just video, its audio also. aftermarket HU's dont have sub out (wired) provisions for that. if you want the oem sub to work, you will need to do a little custom wiring, or add a aftermarket (small) amp to the oem sub

how do u do the custom wiring to make the factory sub n amp work
