I would suggest turning down the gain. Start by turning the gain all the way down Set the volume control to about 75% and slowly increase the gain til it starts cutting out, then reduce the gain til normal sound returns. It will now be set correctly.

Sounds like you are running your subs at to low of ohm. Amps are rated differently on the levels of ohms or resistance that they can get to. If you have a dual 4ohm sub and run it in pairrell it will drop to 2ohm and if you run the same sub in series it will be 8ohm. Your amp will go into protection if the ohm is to low.

Amp goes to protect when I turn up Volume


Recheck the cables to the amp might be too thin or the ones from the amp to the speakers when they're not thick enough or if they're not making full contact with the speakers inputt/ouput connection when you give it volume it demands more power so it causes like a short sending the amp to protection mode

Amplifier goes in protected mode when volume is turned up


Probably the load is too much for the amplifier. Check the wiring/impedance of the speakers.

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty.

The protection modes in these units ****. Most new units have them. What I do is turn down settings on deck and turn up amp as much as possible. Then the protection won't turn on because you won't have to turn it up as high.

My 605 turns off and red light blinks when volume goes past 58


Shorted speakers can cause the unit going on protection mode (the red light blinking) when a certain volume is reached.

Test with a set of replacement speakers.

If it is not the speakers, it is probably transistors in the amp final or something nearby. Test also input output board.

Amp goes into protect mode after volume is turned up


Not enough juice, check the power and ground connections, another possibility is to have dc in the input, try to use in line filter available from radio shack to cut the dc, also test the with one speaker at the time, you could have a bad speaker (shorted) too.

Kicker amo in my old vette


If the amp is in protect mode, it probably has shorted output transistors. To eliminate other possible problems, do the following.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is dropping too low when the amp goes into protect.

If the voltage is OK, you need to check the speaker wiring and the speaker(s). Try it with a known good speaker if possible to see if the amp works normally.

Peavey Bass amp 115


HI Subicbay,

ADjust your Gain setting to limit just enough so the amp does not go into Protect mode. Turn your Gain all the way down, then crank up the bass from your system. GRadually turn up the gain until you trip on protect. Turn the gain back a notch and your set for no more protect.
