Up for sale is my alpine cda-7998 head unit, alpine mrv-f340 four channel amplifier, and alpine xm radio reciever. This is the top of the line alpine radio, retails for 899. There is no deck out there that has the sound control options that the 7998 has, becuase it doesnt have a built in amplifier, i am also selling the 4 channel. I would love to keep it but i need the money. I also have a set of the polk momo 6.5 component speakers for sale. Email me if you are interested at Eu4ia182@aol.com
