    I have a 2019 crewmax SR5 non JBL, when I bought the truck I replaced the factory speakers and factory amp under passenger seat. I replaced it with the TT TXD8005 3/5 channel amp. I wanted to avoid replacing the factory head unit. I rode it out for a few years, but the sound was not much if at all better. So i recently replaced the factory head unit with a Kenwood DMX10057 from Crutchfield. I also added sound deadening to front doors and plan to to the rear doors and rear wall this weekend. I have a Rocksford Fosgate prime R300x4 amp as well as a mono amp. I have 10" sub for behind the rear seat.

    My question is how would I wire up the new amp/mono amp when I remove the TT junk. The TT setup was plug and play for the speakers and remote power. I have new power wire and ground wire to run, no issues there. I'm not sure how to hook up the speakers to the new amp, because the Kenwood HU has rca's that the factory HU lacked. Do I need to use RCA or can I splice into the TT harness? I will be removing the HU to install a Rago dash mount so the rear of HU will be accessible. Sorry for text wall. Just want to give as much info as possible. Thank u in advance

    I would run new RCA cables from the HU to amp, athough it isn't easy.
    Unless your amp have speaker level inputs, then you can use the inputs at the OEM amp.
    You can use this harness to access OEM amp wiring without needing to splice it.
    It has speaker input left/right front/rear and door speaker output left/right front/rear.
    It also has the remote on for your amp.

    You can find wiring diagrams here..

    And remember with your OEM wiring, the dash speakers and rear tweeters run off the HU, the door speakers run off the amp.

    Thank you. Ill order that harness. Do you recommend the RCAs from rear of head unit because of better/cleaner sound? Or does it have to do with the inputs of the amp? I have no issues running wires or cables if that is considered best practice, I will most likely have the center console out for deadening and adding rear chargers to it. The Rockford amp has "speaker level inputs" with a 4 prong Molex female. I guess I'm asking because I don't know which is better, RCAs or the speaker lvl inputs, honestly in not sure what those are. I have more research to do, thanks again for your help. I've read a ton of posts in this forum and on this site, there is a core group of people who always answer folks questions or point them in the bet direction, and you sir are one of those people.

    I ran rca cables from my headunit to my amps and dsp

    I also ran all new speaker wire through the front door boot and dash locations ,, was not hard to do.
