Question about PPI PC1400 Car Audio Amplifier
Since it's an intermittant problem and a relatively expensive amplifier, you should have it checked by a qualified tech. If you keep trying to power it up, it will eventually blow out the power supply transistors which will add as much as $100 to the repair bill.

If the fuse only blows after the remote voltage is applied, the output transistors are likely shorted. To eliminate the speakers as a possible fault, disconnect the speaker wires from the amp. Also disconnect the signal cables.
If the fuse blows without remote voltage applied, either the power supply transistors are blown or the B+ and ground are reversed (or they may have previously been reversed).
