Guys if I can make a recommendation please get proper HU's.
Get at least a Kenwood, Pioneer, Sony or JVC unit.
The signal quality from the cheaper units are just not up to scratch.
I used to run a Sony HU that retailed for R3500 and the SQ was brilliant. Lately fong-kong seems to be churning out a load of cheap DVD players and they all suck. Seem great for a start but down the line they all croak and you are left shelling out for a new unit. Remember that good sound comes from good head.
My latest sound project uses a JVC In-dash DVD player with motorised screen. Retail is around R6k and its well worth it. The quality is mind blowing.
Also don't skimp on the front stage. Get some quality splits like Hertz, JL, DLS, Rockford, etc. The cheap ones are just nasty.
Most important of all. That amp with 300000W output is most likely only rated at 65W RMS per channel.

For subs make sure you have a proper box built. I used to run 2 x 12" Pioneers in a box that was built to house one and its sounded good. I then dropped the one sub and switched to 1 x 12" in a proper box and it pounded my nuts. Proper box dimensions matched to the requirements of the sub is crucial to good SQ.
Feel free to add to the list.
