Ok, I have a 1991 Thunderbird, and want to put in a new deck, however someone told me that there is a factory amp that is located somewhere in the car, and that installing a new deck will not work and if it does, it will sounds like crap..... is this true?
If true, and if anyone would have experience with this, where would I find this amp to bypass it, where in the 91 Thunderbird would it be located?
