can someone repost the wiring diagram for the stereo

also when i install the amp, do i connect the speaker wires directly to the amp, and run the rca cables to the radio

or

do i coonect the speaker wires to the radio and from there cut and splice the spweaker wire to run it to the speaker connections on the amp

thanks
