Amp is T1000-4
Amp has rail voltage but no regulated voltage.Across pin 4/8 of the op-amp i see 3 ohms.From the output of the positive regulator to output of negative regulator i see 24 ohms.Do i have a shorted op amp or the is some other components i could check?

Desolder pin 4 and 8 of each IC until the short goes away.Easier with TH but doable with SMD

It will be very difficult to do.This amp has more than one vertical crossover board with op-amps.
Any other way to spot a shorted op-amp

Temperature can be an indicator. Freeze all of the components with component cooler or an inverted can of canned air. Let the white condensate//frost form on the components and then switch on power. If one op-amp defrosts much quicker than the others, it could be defective.
Perry’s idea is a good one and I would try it first
However this may be an alternative, How hard would it be to desolder one vertical board at a time? This may be a way to narrow done the defective component to one board and once the board is isolated and removed from main board,apply the technique I recommended in previous post.
I'm not familiar with the layout of this amp and most Kicker amps have the x-over on a separate plug in board. Although, I've had to go through multiple op-amp chips to find a failed chip.Tedious and time consuming but with a little patient and care can be done.
