Audio Systems: 1997 Honda Prelude Factory Amp, bose amplifiers, 1997 honda prelude

Question
I am installing a new stereo in my 1997 Honda Prelude.  It has all of the factory installed equipment, including an amp in the rear.  The store where I bought it did an install, but did not account for the amp, and I have no balance control on the rear speakers.  Is there an adapter or harness that I can use to integrate my factory installed amp with my new stereo?

Answer
if it is a bose amplifier it needs to be remove and new wires run from the amplifier in the trunk to the new radio

i will go  back and tell them to rewire if not get your money bck
what kind of shop didn't notice of this
that guy that work in your vehicle needs to go out and lean the streets  and not touch a car again untill he learns about factory car audio systems and bose amplifiers
alsonew radio needs to be able to power 2 ohms speakers
that is what you have in the prelude

good luck
