My Jeep came stock with the sales code 'RAS' A/M-F/M stereo with cassette player, though only the radio functioned when I bought ... Show moremy Jeep. I installed a Sony CDX-GT360MP A/M-F/M stereo w/ single-disc CD/MP3 player, 3.5-millimeter auxiliary input jack, Radio Data System (RDS), removable front faceplate, and 52 watts per channel, 4 channel integrated amplifier. It also has SIRIUS-XM satellite radio capability, though I don't plan on adding the service. It looks great, as you can see, installed into my Jeep's factory dashboard, and wasn't that difficult to install and set up. Soon after I installed my new radio, I noticed that the four 6X 3/4" stock, non-premium door speakers in my Jeep were blown. I decided to replace them with two pairs (four total speakers) of Pioneer TS-G1644R 6X 1/2" 250 watts maximum power speakers. They look great and weren't that hard to install, plus, they are hidden behind my Jeep's door panels, and you can only hear them, but not see them, which is a plus, as I want awesome sound that doesn't stand out visually. They sound great and don't rattle or crackle, unlike my old factory speakers did. I don't plan on adding an external amplifier or amplifiers, or subwoofers, since my Jeep has good sound already with the Sony stereo and Pioneer door speakers. (: Show Less
