Answer 1

If the 4 channel amp has high level in(speaker wires) then wire the speaker wires from the radio straight into the amp, then use the RCA's (sub out) and hook it up to the sub amp so you can control your bass.If you only have RCA inputs , then use y splitters at the input of the amp then use the RCA outs to hook to the sub amp.
