i am a mecp installer. im not the best in the world, but im not a complete idiot. i work at best buy, and recently did a sub/amp install on a 96 cadillac sedan deville. it does have the bose system, so i simply used the line output converter, on the output side of the bose amp. they are correctly in phase, so i know that is not the issue. however, the amp will continue to shut off, almost like is overheating and going into a protect mode. the amp will come to the point where it literally turns off, and doesnt even display a protect light. it is a kenwood amp, and im not 100% sure it has an indicator for it. i have checked the ground and changed it to make sure that was not my problem. i know at times an amp can have strange problems from a bad ground. i also made sure the connection at the battery is nice and tight and used a long post adapter. i used an accurate fluke meter at the front on the battery and on the amp as well. when it shuts off, there is no voltage drop below about 12.7ish (which i still think is low, but not low enough for shut-off). i have checked the ohm load on the subs. it is 2 ohm mono, and both the coils read stable 4 ohms each. so no problems there. do you think this could possibly be a problem with my input? like i said, its the rear speaker signal, on the output side of the bose amp. and i do know they are in phase. if one of the stock speakers is blown, do you think that would cause any problem even though its tapped in before the speaker location? i am very stumped here. this is his second amp. his first one did actually have a bad channel, but this stil shuts off and gets very hot. i cannot explain it. the amp will not do the same thing in another employees car, we checked. any help is appreciated.

One way to know forsure is take a bench radio and run a set of 20' rca's the amp whilst it is still in the car and see if the same problem occur's.

It is very possible that the amp is going out. Those older cars are known for having troubles. Most of the time I just bypass/disconnect them and put the LOC between the speakers and the head unit. I did this in my old Infiniti and it sounds great and obviously the old amps arent causing problems

96 caderact? Most likely you are over loading the loc, try a differnt tap and use a test speaker to check the tap, if the test spk is going nuts, you could be simply overloading the rca input on the amp
