How to add another amp to my systems?

Question

I currently have a 600watt amp running my door speaker in an F150, I am getting custom subs boxes made and was told I need to add another amp for these, the subs are Infiniti 1052W's with 250 RMS and 800 watts peak handling, How do I go about doing this? or is there a way to run the subs and door speakers off one amp? The current amp is a Pioneer 4-channel bridgeable amp

Answer 1

get a distribution block and a cap wire from battry to cap to distro block to the two amps, and for the Pre amp outs if you amp don't have a output use a Y splitter and hook to both amps and just splice the remote wire and tap a wire to the other amp
