    im having the same problem, its the Legacy LA-1030 1000 Watt 4ch Amp and it has the option to bridge each 2 channels (so you end up with a 2 channel amp) and i have 1 4Ohm sub bridged across channels 1 and 2 and channels 3 and 4 are empty when it starts pushing the subs its not clipping or anything, but it goes on protect. whjat do I do to fix this because to get a new amp is about $350 which i dont have for car audio right now but i would really like to keep my system.



    please help.

    If it goes into protect with no speaker wires connected to the speaker terminals and no RCAs plugged in, it likely has shorted output transistors. Read through the following page if you want to try to repair it yourself. Let me know if you have any other questions.

Do the speakers push out or pull in when power is applied?

If not, how did you determine that is has DC on the speaker outputs?

9 times out of 10 if your amplifire is in protect mode and evrything externaly, like speakers, fuse, voltage, etc. checks out fine then
either you have shorted out output transistors or power mosfet transistors. Basicly that just about what happens with car amps.
It's easy enough to fix IF, IF you know what your doing. First you
need to check the output transistors with a digital volt meter on diode check, If they check out then check your power supply mosfet transistors. I can almost guarantee this is your problem. Very common. I buy non working amps all the time and repair them. Listen to pbabin also he has helped me out. Good luck

SOURCE: LA-1030 Protect Mode

you have an unloaded channel,so the voltage is exceeding what the protect circuit is supposed to see.you have to connect an 8 ohm resistor across the output of the unused channel.
do not drive a signal into it or you will smoke the resistor.
a 10 watt will do ok with zero signal input

Protect light is on ,no sound?


Make sure you have a good ground connection. The ground wire should be solidly connected to the vehicle chassis in a paint-free location. If the ground is connected badly, the protect light will come on.

My amp keeps going off on protection mode as soon as the bass starts bumping


check powers and earth, unplug sub and crank it up see if it still goes into protect if it doesnt the sub is too much load for that amp and could have damaged the amp, if it still does it then its a fault in the amp or power problem make sure you have good thickness 4gauge and good earth

Protect Mode


Your probably not pusing enough wattage to the amp. Look into buying a capacitor for your set up. and you may need to run a thicker guage wire to your amp.

Power light turns from green to red protect mode and then there is no sound coming from my speakers


there are 2 reasons for it to be going into protect mode 1 is heat 2 is the load on it. if it is going into protect mode soon after it starts there is a problem with the speaker. if it is after it has been on for a while it is that the amp itself is overheating. hope this answers your question
