Hello jcox7704,
Your head unit is 50 watts X 4 channel maximum power and 21 watts RMS so it's possible that all you need is more power to the speakers. But even 21 watts RMS should be enough for normal speakers. Before investing in an amp, I'd check the speakers and their wiring. Measure the impedance (resistance) at the head unit side to see if they match up.
Hope this helps.

This is the mesage it will display when a short in a speaker wire or
speaker with low impedence is hooked to the internal amp and sends it
into protect mode, shutting down the amplifier section while the rest of
the unit continues to work.
check all of your speakers are not touching metal

Hey Adricat, did you get a solution to this problem? I have had this happen twice now, and each time it was replaced by the shop i bought it from.
