[QUOTE="BCotrell, post: 8529039, member: 666314"] Honestly u could have googled this first and then created a thread with clarification questions. This answer is probably super drawn out diagrammed on crutchfield. If your headunit is aftermarket you run rca cables from the preouts in the back of the headunit (labeled front/rear). Your existing sub amp would likely be plugged into the sub pre out. If your headunit is factory and you have an line out converter check to see if it is a multichannel(needs to be 5 or 6). Also, if your 4 channel amp is newer, check to see if your amp takes low level (speaker) factory inputs and converts to high level outputs. If so u can use it as is and leave everything else alone. If none of those options work and your hu is factory you can replace whatever is connecting your sub amp to the factory headunit with a module like this: [URL="https://www.amazon.com/gp/aw/d/B00ATHBO86/ref=mp_s_a_1_1?ie=UTF8&qid=1477807950&sr=8-1&pi=SX200_QL40&keywords=lc7&dpPl=1&dpID=51y0DmpKP7L&ref=plSrch"]https://www.amazon.com/gp/aw/d/B00ATHBO86/ref=mp_s_a_1_1?ie=UTF8&qid=1477807950&sr=8-1&pi=SX200_QL40&keywords=lc7&dpPl=1&dpID=51y0DmpKP7L&ref=plSrch[/URL] Good luck [/QUOTE]
