How do I get my MTX Terminator TNA251 out of protection please. It's driving me crazy. Is the amp no good.

Wire the two kickers in Parallel, this will half the resistance of 8 ohms to 4 ohms and match the 15" speaker on the other channel.

sometimes the problem isn't noticeable. it could be a problem in the circuitry itself. how old/new is the amp? is the ground solid? what gauge is the wire? try hooking it up to the battery directly and instead of hooking up the remote wire from the head unit to the amp use a "jumper" (short wire) to connect it from the amp power wire terminal to the amp remote terminal. if its still in protect after that then the amp is bad and needs repair...

The most common reason an amplifier goes into or remains in protect mode is shorted output transistors. To eliminate other possible reasons for it to go into protect, read the following page.

Something is not wired correctly ,Check crutch field advisors website for detailed wiring instructions.

Your amplifier is 4 channel... and only 2 ohm stereo capable.

You will get the most power putting 1 subwoofer wired in parallel on each BRIDGED channel.

This will give you a 2 ohm stereo load.
