800a is the base model Raptor, unofficially the R model...fewer made and will be worth more than those fancy 801a models
lol
What I did on my 800a, I upgraded the audio to the plug and play Ford Kicker System. All Kicker equipment, DSP amp, 4 door speakers, 10" sub enclosure with 200W amp and all factory plug and play wiring harnesses (all components have "Kicker" insignia and Ford Part Numbers labeled on them). Takes only half a day to put in yourself and sounds great (much better than the Sony system). And for less than $900 it's a great deal for what all you get.
