i have a 2005 jeep grand cherokee with the boston acustic system and i recently installed a kenwood flip out tv when i went to wire the headunit in noticed that there is no 12 volt on off wire just two constant feeds so no i had to wire it so the radio stays on a nd i have to manuly turn off the radio when i turn off the car. I was wondering if anybody has the wireing diagram or a way i can fix the problem

Go straight to the ignition harness for the switched ignition wire. It's PINK/LIGHT GREEN at the harness.

if the vehicle has the 8 speaker system then it has a factory amplifier in it. These new systems don't have a traditional "amp turn on wire" and are turned on via the factory radios databus output. Currently I believe that soundgate is the only manufacturer that is making or developing an interface for this. there are two feed input signals coming from the radio, and from there the amp does the rest. Two options, find the amp and re-run new wires to each speaker...
relocate the stock radio, so that it turns on the stock amp via the data wire, and feed your audio signal back into the stock amp...
neither of which are easy bang bang.. Good luck.. -------------

lol... Thanks.. You said the same thing I was thinking.. I found out that the 2005 Grand cherokee's have a Boston Acoustics 8 speaker amplified sound system with sirus sat. that are more complicated than we can imagine.i spend a few hours trouble shooting this car..I dont't reccomend anyone changing the head unit on this vehicle.. If anyone is planing on upgrading the sound system on this vehicle than be prepared to spend some bucks on new amp, wires, head unit and maybe speakers( i did not test the ohm's impediance for these Boston acoustics). Thank you and good luck to all the new 2005 Grand cherokee owner's.

I'm running into that same issue with my 05 Jeep, however I think my Boston system is only 6 speaker, 2 in the dash, 2 front door, and 2 back door. the 276 watt amp. I am wanting to add a sub, I can use high level inputs on the amp, but thought about upgrading the HU, found out it will be more expesne than I originally wanted.
New HU, steering wheel control adapter, run new speaker wire, and either run speakers off the HU, or buy a 4 channel amp on top of it, then upgrade at very least, the front door 6x9's.. Ugh... might just stick with the add on sub/amp for now.
