SCM, Not enough burn in for sure, but more going on here. Also, the 16 gauge with speaker less than 95db is not a good match...,especially with long runs. Need more info.... Was it an SS amp with speakers less than 95db effecient? If so, not an ideal match. Under 8 ohm speakers? Perhaps 4 ohm? If so, not the best match for 16 gauge single runs.
