Yes, that is an amp in the trunk. The other amp was removed along with the subwoofer when the rear seat was put back in. They go with the car if wanted. This is a street car, not a race car and has good street manners. I am running Nitto drag radials and at 15 pounds of boost they are at their limit for traction. I can only guess from comparable builds I've read about that 450-500HP is easily within reach with this setup. Tranny is stock and works great. AC needs recharging. I never used it. This car has never been raced on a track and only one short street bout with a vette.
