Hello , has any one attempted to quad amp a pair of 4350's? i have 2- 4 way crossovers i can use in mono and was thinking of using each crossover for 1 speaker and not use the internal one. it sounds great the way it is but was thinking of attempting this. i know it would be a challange to set up but it might be fun or is this just diminishing returns. i have tri-amped a pair of soverigns in the past with mac tube amps and it was great. Would appreciate the good, bad and the ugly comments on this idea. Also any comment on adding a second 077 to each cabinet?, thanks
