Yes check the wiring, very low OHM'* can kill many amps, especially 4 ways, but it'* a JBL, and they are usually under rated. Just make sure you're doing what you can do, and you have the wires the correct way (series/parallel).
Also check for shorts crossing between wires. The first time I installed a sub/box/amp in my last car, the box'* own Input box (where you hook it up) had a slight cross going thru it,and whenever i would run serious power thru it it would send my amp (JBL) into protection. The light flashed, it clicked when it went into protection mode too. I had to throw in a new one into the box.
