This is a Sony XM-2351 car stero amplifier. I purchased it new many years ago and no longer have a need for it. I powered it up and it's fully functional. Rated power output is 35Watts per channel, 2 channels, at 0.04%THD, 4ohm load. The manual is still available on Sony's website if you need futher information. For payment I can accept Paypal or money order. I can give you a shipping quote anytime if you send me your zip code. If you have any other questions feel free to ask. Thanks for looking!
