A pair of Harrison Labs FMOD RCA Inline Low Pass Crossover should work.

If you need to feed the subwoofer amplifier from your radio speaker output, add a LOC.

Radio speaker output > LOC > Inline Low Pass Crossover > subwoofer amplifier

Most subs have built in low-pass filters.  If you can get a line level (lower than speaker) signal then you are all set.
