thats a cheap cd player. i got money on it that is between 2v and 2.2v. not positive though, but most likely thats what it is. all cheap pioneers and kenwoods are 2 - 2.2, and sony is no different

the 4 volts will give you a better signal than the 2. and then you will have to adjust the gain on your amp, and the bass will be different at diff volume #s on the HU, compared to now.

the SQ will get better because the signal is stronger
