Amp going into safe mode acts like its not getting enof power, power and ground are both 4 gage and hooked up corectly

first check all connections, fuses and speaker wiring. Check to make sure that the amp is getting enough power to keep it running, meaning a piece of 4 to 8 gauge minimum wre from your battery to the amp. Make sure no wires are touching ground on the speaker outputs all the way to where they connect to the speakers. You can check this with a Ohm Meter to see if their is a direct short to ground. Or unhook all speakers and 1 by 1 touch them onto the amp to see if it cuts out. If the amp is going iinto protect mode without any speakers hooked up to iit (I have a bad keyboard sorry for the extra or missiing I's) and all other things I mentioned are OK then your amps bad and needs to be serviced. Hopefully It's just be a shorted speaker or wire.

at least a 8gage and that for your ground if not better then that make sure you have it grounded right and to bare metal or else you amp will have cooling problems and most likely go into protect mode

hope this helps

Your problem, as to my knowledge, seems to be more of a ground issue, or power supply issue. Check the grounds throughout your vehicle, including the ground for the fuel pump.

The Peavey XR8600 is NOT just an amp, but a powered mixer.

To SAFELY use this with your powered speakers, connect those speakers to the MAIN and MONITOR outputs on the front of the unit with 1/4 inch INSTRUMENT rated cables (NOT speaker cables).

To safely leave the power amps in the XR8600 with no output loads, plug GROUNDING plugs into the POWER AMP 1 and 2 input jacks on the front. This will prevent the power amps in the XR8600 from running with no load which COULD damage them.

Make the grounding plugs from 1/4 inch mono plugs by jumpering the centr aand sleeve terminals of the plug.

you might need to turn the amp down and get some better wires to carry the load. when at lot of juice is being tranfered you need good wires to hold it

check for earth

it isnt getting enough power and its tripping the internal switch on the amp and putting it in safe mode. either your wire isnt a high enough gauge. you might need a capacitor or you need bigger wire.

Check your ground wire and put your setting on your amp to low HP LP FULL also check the radio wires

what gage power wire are you running sounds like you need a smaller gage wire i have mine hooked up to a 4 gage wire and its working great

If the subs are rmoved from the amp (wiring), does the amp still go into protection without them hooked up? If no, shorted sub, if it still des, unplug RCA's, does it still go into protection? Also check voltage. Make SURE you have greater than 12 volts AT THE AMP using amps ground to check the power AND remote wires. Hit me back wth an update.Those amps rock.
