Im pretty new to car audio but i did an install of subs a few years back but then sold my car so i pulled the subs out and decided to hook them in my new car. My new car does not have preamp outputs on them and i do not plan on replacing the head unit. Im running 2 rockford P3s both of which have there own monoblocks (r500x1d) The amps both have high level speaker inputs. I spliced into the rear speakers and hooked the connected into the high level slot. Now the sub with the input is playing loud and clear however i am running RCA thru the pass thru and into the input on my other amp but no audio is produced. Put amps have the same power and remote wires hooked up. Both lights are on on the amps just no audio from the other sub. Do i need to run a high level input into the other amp as well? (side note: the RCA cables are putting out 0.11Vs from the first amp. Wondering if there just isnt enough power?) thanks for any responses.
