deh80prs

Is mine faulty or do USB cords not plug in all the way? I know it can screw up the signal sometimes if they somehow get tugged on a little. Also, the other day i was doing some sine wave tones and had muted everything but the midwoofers, which were crossed at 4000hz/63hz for the time being, but...

So im on my 2nd unit from ABT (both manf. date of 5/2014) and they both have the same under the plastic looks like scratch near the 3.5mm jack anyone else have this ? 2 units in a row with the same marking 1st unit 2nd unit
