I did the individual speaker test already. The problem seemed to stop for a bit when I didn't have one of the speakers connected. The amp went into protection again about a week later though. I sent my old speakers away on warranty and got new ones and ran new wire to all 4 but the amp is still going into protection. I will test the rca's tomorrow though.

Thanks everybody for your replies!

Is there a chance that the polarity is incorrect? Usually if an amp goes into protection it signifies a feedback from the speaker that the amp doesn't like. Overdriving the speaks can cause this, reversed polarity can cause it, grounding issues can cause it as well. Where are your gains set to? Have you tried lowering all gains and ramping up the volume to see if it goes into protect? How solid are your connections into the amp?

Try upping the crossover frequency a bit for all the speakers.

^^^^
That too LOL

I am having the exact same problem as you! I checked all the wiring, made sure it was 4 gauge power and everything. Yet still, every time I play a song at a reasonable level (about half, depending on where the gain is), especially when there is some bass, it will short out once it hits hard. I cannot figure it out. emarciniak, did you ever get it squared away?

Turn the gain all the way down and try. You might be clipping the hell out of it causing it to go into protection.

This actually started happening with the gain all the way down.

I thought clipping occurs when you underpower speakers right?

nnnno.... clipping occurs when the amp is set too high. It will "clip" the wave flattening the "peaks" and "dips" causing the speaker to "freeze" usually resulting in baked coils. Some amps will go into protect when they are clipped too hard. If he has gains cranked, certain songs might cause it to clip at abnormally low levels. Also high levels of boost will cause an amp to clip.

The way your thinking is if you underpower a sub, therefore, set gains too high (trying to compensate for lack of power) which then causes the amp to clip the signal to the speaker.

Hmm, gotcha, well like I said, I had it with the gain all the way down on the amp and it still happened. Very odd.
