Great amps, and I would ask if it has been tested,if not,id ask if theyd take $30 for a non tested/no gauranteed working amp, and maybe you will get it for that??Just take some speaker wire w you, and check amp at the car battery is what I do,just to see if she powers up,ground to ground,and remote and power to power she if she lights up,even.Good amp though,and worth the money
