i picked up a thunder 5400x, but the sub output is blown. i want another 5-channel amp to run my whole system, and found a blue thunder pro400x5 for pretty cheap. is this amp worth it? is it pretty much the same as the 5400x? the specs are almost identical, with respect to the crossover frequencies. but one thing i noticed was that the 5400x specs were --watts x 4, while the listed specs on the pro were --watts x 2, but it says it's a 5 channel amp. just trying to figure out the best option. input please.
