PPI Art Series (Black) Ax400

Description

PPI Art Series (Black) Ax400, I bought it a while ago and never installed it.
I did test it and all channels and filtering work. The test was not performed under heavy load just some 8 ohms speakers for 1 hour and all 4 channels were tested. Selling as working because everything works and sounds clean with no fuzz or background noise.
Looking at the last picture it is seen the amplifier was opened at some point based on the broken factory seal. I do not know the repairs (if any performed) i am just making the point to say the amp has been opened at some point in it's life.
Yes, the amplifier comes with all three plugs to interface to it.
