let us ken wot the dvd player like a was looking at that one in halfords the other week but decided to leave it the now

as for the amp if your wanting to power both the sub and 6x9s you would be better off with a 4 channel amp as you couldnt run the sub using "normal tones" above a think its 60htz as this will damge the voice coil.
if you have the crossover on the amp set to low and around 40htz this will give you the bass for the sub but the 6x9s will also run in this range . plus the wiring required is not always possible with the amp i know my alpine amp can do it but it requires resistors and sunthing else, i had a quick glance through the instructions for the 1500w amp and couldnt see it in there it only showed left and right speaker) wot you would be better to do is connect just the sub to the amp and run the 6x9s off the head units amp. as you say there already in the car a take it there wired into the rear speakers . if not thats were i started

disconnect the rear speakers and connect the 6x9s to them and have the sub run off the amp until you look at buying another amp when/ if you do go for a mono amp also called class d to run the amp and us your current amp to run the 6x9s ( or 2 sets )

also as your getting a 1000w sub and 1500w amp it would be a VERY good idea to get a power cap to save your battery and all eletrical systems in the car (min 0.5 farad per 500w) so would idvise you to go for a 2 farad one, 1 farad min. hav a look on ebay as i got mine off there for £35 my local "car shop" had the exact same 1 for £80
