Old deck, new subs

[dougb2k1]

I have a Kenwood KDC-715s deck and am installing an amp and subs. There are two RCA's on the back of my deck, one being front and one being rear. Which one will go into my amp? Both seeing as how its a two channel amp? I know most newer decks have a sub preout, will mine not having one affect anything?

U can use any one you want, crappy thing is you'll have no control over the sub volume. well unless u have a remote with your amp.
