Sounds like something is shorting out and it is in protection mode. Check that the wiring is correct and there are no bad spots on the power wires. Unhook the power before starting your evaluation and leave disconnected until you think you've found the problem then rehook the power source. This will give the system time to reset if it needs to.

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. Hopefully you have warranty D .A thumbs up would be greatly appreciated if this answer is helpful to you. nitro-lv2kkrmxrai4iihdvw4m3np2-1-0_0.jpg

Directed audio 800a amp the protection light keeps blinking


1. Check your grounds. (including grounds for your stereo)

2. Check to make sure the power cable you connected to your car battery is properly connected, and not coming into contact with anything metal.

3. Make sure you are using proper fuses.

4. Check your connection from your stereo to your amp, and your amp to your subs.

Generally, the power light is green and the protect light is red. If the protect light is on there could be a short in the wiring or there could be an internal fault in the amp.

Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down (goes into protection), the amp likely has blown output transistors.

Mac-505 amp



Disconnect all speaker wires and signal cables from the amp. If it powers up normally (no protect light), the wiring needs to be checked. If it still goes into protect, the amp likely has blown output transistors.

Red light


It sounds like the output transistors have failed. Disconnect everything from the amp except for the B+, ground and remote and turn the amp on. If it goes into protect, the amp is in need of repair. If you want to repair it yourself, email power acoustic for the schematic.

Red LED "Protection Light is on" What is the problem


The red light means the amp is in protection mode. A few things can cause protection mode..... First disconnect the subs completely from the amp, and turn it on, if it powers up you have blown subs. Also try checking the main power wire at the battery...sometimes the current your meter is seeing is backfeeding from the remote wire, so your main power line could be blown at the fuse under the hood. hope this helps

switch off the amp then take off all the wires off including the speaker wire and then reconnect the wires on like before the problem is that the amp is on protection and if that dont work then get it repaired another thing is make sure ur amp fuses havent blown.
