I picked up the above car last week and I'm flummoxed by the speaker system in this car. Dash Speaker Dash Tweeters L/R Front Door Speakers L/R Passenger Door Speakers Parcel Shelf Speakers - nothing zip nadda. Now I have read here that its a real pain changing over the standard head unit, so lets forget that for a minute. How come there are no rear rear speakers, they haven't been removed there is just nothing. How easy or hard is it to mount an amplifier to the head unit? Looking under the parcel shelf through the boot there doesn't see to be anywhere to mount rear speakers, so how hard easy to mount speakers there?
