Message:
this sound right? for a club cab r/t.
keeping factory head unit=mitsubishi chrysler(infinity i guess).
3 band equalizer cd/cassette attached to factory amp.(which will be ditched).
new custom amp= 2 channel...
will connect front(components) and rear speaker(coaxels) to each channel.
i need to install a line out convertor between front and rear speaker on each channel. correct?
I need to install high low convertor to adapt the speakers on the old head unit to rca. correct?
I need to install a resistor between front and rear speaker on each channel to prevent rear from overpowering the front. (150w per channel rms..what size resistor is best?)
i can't see why i need a hi/low convertor except for needing rca's....i mean the factory head unit was amped externally so it should not need it's output signal changed to match the new amp...right?

No, a line output converter doesn't install "between" channels. most will take two speaker channels in (four wires) and have two RCA channels (two jacks) out. You need two convertors total, one for the front channels and one for the rears.
"I need to install high low convertor to adapt the speakers on the old head unit to rca. correct?"
No. The line-output converter does that.
"I need to install a resistor between front and rear speaker on each channel to prevent rear from overpowering the front. (150w per channel rms..what size resistor is best?)"
Why would you need a resistor for anything?
"i can't see why i need a hi/low convertor except for needing rca's...."
well, needing RCAs is a big reason. RCA inputs on an amplifier are designed for a low voltage, single-ended, high-impedance source. The speaker outputs from the head unit are high voltage, differential, low impedance sources.
"i mean the factory head unit was amped externally so it should not need it's output signal changed to match the new amp...right?"
No. The factory amp was designed with speaker-level inputs.
