I done the lazy thing and brought an ASL logistics kit with aux booster (ford one), few problems though, sound is great, better than through the existing premium unit but has a slight turbo noise coming through speakers when turned right down, will be putting in a noise suppresor in to fix that hopefully. The other problem is that I brought a sony DVD head unit as I didnt want to use them cheap Boss Audio ones that ASL use, but it bit me in the butt as the sony can be turned to NTSC, but when a PAL DVD is put in, automatically changes output back to PAL, hence doesnt work, I have brought a pal/ntsc convertor from jaycar but all it done is give pal colour, still jumps around. So I have to change the player. From what I know, Boss audio work and seems like JVC work, anyone else use anything different and work? Dont want to fit a player that will last a month before it stops playing DVD's.
