I have just replaced the entire Bose sound system in my 98 Eldo ETC. I ran all new speaker wire to the door and back deck ran new Battery cable from hood to trunk, made new pods for door speakers, got every thing working correclty even the memory for the deck and XM brain box. but I am still having some issues with the security not disarming after the car sits over night, nor the remote locks. I know I am going to have to pick up a convertor box to replace the radio memoru functions that deal with the "rap" functions. but there are about 4 on the market from good companies I would advice on what people have found with the different brands. just keep the comments nice, I am not brand loyal on this type of device. Any help would be great. the system I replaced OEm with is as follows: head unit=Pioneer DEH-p4300dvd, W/ Pioneer XM add on, front speakers-Boston Acustics SR80 plates, rear speakers=Boston Acoustics SR95.2 Amps=main Rockford Fosgate Punch 4080, 40x4, Sub amp=Rockford Fosgate Punch 100 bridged 2ohm. Subs,=2x10 Rockford Fosgate Punch in 4th order bandpass tuned to 42hz.
