aftermarket HU with stock amp? ok, i am sure this problem is common but i installed a pioneer head unit with the factory amp still in the car. the radio will cut out at a certain volumn level which is vary low. also the voltage booster also causes it to cut out but that i am not worried about. i have been told that the factory amp needs to be bypassed, that the amp draws to much current cause the breaker to blow. if this is the case and i need to remove the amp to correct my condition, is there an easy plug in harness or do i have to wire in one from scratch, eaither way, it is no problem, i just need to know exactly what to do which no one has the answer for. 
by the way, it is a 94 Formula, i believe with a monsoon system, 6 main speakers with the amp in the passenger rear side panel.

What "voltage booster"?
Did you check the FAQ:

i know the amp needs to be removed, just need to know if there is an easy way

A Monsoon amp should not need to be removed - it is quite capable of running off an aftermarket head unit.
There's a couple of things though... the 94 f-bodies never came with a Monsoon system - they had either an "extended range" system or the premium Bose system. If you have a Bose system then you will need an adapter to make the head unit work properly. The Bose system had a special head unit that produced high-impedance, line-level output into speakers that have individual amps attached. Plugging a standard radio into that kind of system will cause exactly the symptoms you describe. You can find Bose adapters on the internet - otherwise you'd have to replace all the speakers because the amps are built in to each one and can't be bypassed.
Now, if you have the "extended range" system then I would suspect that the 16 - 16.5 volts is too much for the head unit. They are designed for 14.5 volts and you're talking about 15% overvoltage. That could be exceeding the tolerances of the unit.
