hey mate, its a pretty basic job to get it done, the speaker, power, antenna etc colour code thing should be on the back of the stock tape player... just use that as i guide with the colour code for the new ones manual n go from there... cut the old one out, solder the new wires in plug it all in... put it back together n dun
rear speakers r peice of piss... only thing is in the 34 u will have 2 take the whole parcel shelf out, which means taking the whole back seat out lol... its pretty straight forward tho just a few bolts n awkwardness lol
btw where did u get ur car from??? as i recently traded mine off n i put the dodgy stock system back in lol
