Opened the box to test and take some pictures for you and show Certificate of Authenticity & CEA Power Test Result.

Also tested Gain Knobs using built-in kicker lightening and multimeter, but AMP was sold to me as New initially, just never used..

Probably can NOT find this particular AMP model anywhere new in any country, mostly only used versions are listed on rare occasions, I had to actually look long and hard to come across it beginning of this year 2025 overseas and paid top dollar for it including overseas shipping.I believe they quit retail selling them in 2020 timeframe or thereabouts, but it features the nice RED Light Bar and is 2 Ohm Stable x 4 Channels.
