I have a keenwood indash dvd player i want to hook my amp to it but it dont have rca jacks so how do i do it

If your indash radio does not have RCA outputs, you can do two things. You can purchase a line level converter and hook it to one of the rear speakers. This will allow you to tap into the speaker wire, then convert the signal to RCA. Then you plug your RCA cables in there. The other (my recommendation) is to purchase an "add an amp" wiring harness. This harness will install between your radio and vehicle harnesses. It will have RCA output and remote wire. Then you run those back to your amp and there you go. You can find these at the scosche or PAC websites. You can also try www.crutchfield.com
