This is a Sony XM-752X car stero amplifier. I purchased it used several years ago and no longer have a need for it. I powered it up and it's fully functional. I can't seem to find a manual or the specs for this amp, but as I recall it's rated power output is 75Watts per channel, 2 channels, at 0.04%THD, 4ohm load. It also has level adjust, adjustable high/low pass filters, and adjustable low boost for each channel. It is bridgeable. 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!
