Can This Amp Power A 50 Foot Speaker Cable Run?
I ’m with zavato, the cable should be ok, most important thing to consider is the amp has enough power for such a big theater room without clipping and destroy the speakers! http://myhometheater.homestead.com/splcalculator.html

Tim, my guess is a combination of difference of ESR and those old electrolytic caps dried out and out of specs, so a tester that can check the value of the caps and ESR will give us the answer.One thing that surprised me was the cables made such...

Btw, all cap in the crossover should be bipolar/non-polarized, therefore the two 2200uf connected back to back.

If caps are parallel, measure it in circuit.
