ok guys, I have a mk3 gti & I am totally unconfident about installing wiring, amps, subs, whatever and dont want to make a pigs ear of everything - so i got 2 questions;
I already have the HU - ripspeed dvd-730B (any reviews on that one?)
1 - for around £500 do you reckon I'll get everything i need bought and fitted for a decent system
or
2 - is it easier than I think and with no knowledge of this whatsoever do I dive in and see what happens

3 - Can I get decent sound by simply replacing the dash, front and rear door stock speakers
any help really greatly appreciated from you pro's
