low impediance light 300/4
 

OK i have a jl300/4, right now times are to tough to send it into jl to be repaired the "right" way.

this is what happens,
it powers up and plays the music fine at low sound levels, when i turn up the head unit it cuts out then once i turn it back down it comes back on.

once power is sent to the amp the power light comes on then approx 6 seconds pass and the low impedance light comes on.

i know it is the amp itself, i bench tested the amp (with a battery outside of the vehicle) and the lights came on.
