http://www.maximaclub.org/5th-howto.htm . Using the RCA converters approach can get a little tedious. You will have to cut the factory harnenss and wire the converters to the radio, run the RCA cables to the amp, and run the wires from the amp back to the cut wires to the rest of the car. I have done this a lot and know a thing or two. Hope this helps.
Sorry Coolhand, but that only works if the car is non-Bose. If you use the RCA adapter lost will turn a low level signal to an almost no existant signal. In order to use you method, you must hook in the adapters after the Bose amps, then run the RCAS to the amps. In effect you will change a digital signal to analog, reduce it to a semi digital signal, input it to the after market amps, boost the signal and turn it back to analog. It works but produces engine noise, clips at 75% volume and pops when you change tracks, or radio stations. There is no easy way around the whole thing. Replace the radio.
