Speaker crossover caps are not high failure and usually not dangerous to other parts when they do fail unless you run at very high volume. Speaker crossover caps are usually non-polarized and should not be replaced a single with polarized lytic. (You can make a non-polarized lytic with 2 polarized lytics of 2x capacitance connected anti-series meaning series with the 2 positives or 2 negatives connected together).
Almost every RCA is prone to the speaker terminal rivet breaking off... just one of that brands quirks.
