Amplifier keeps going into protect?

[imhungnurnot 9]

I have a Autotek MM1400.1D and Autotek MM75.4 in my truck. I leave my truck parked for a few days at a time at school. The 1400 goes into protect mode when I turn my truck on after its been sitting for a few days (I leave the radio on all the time), but when I turn my radio off then on again everything is okay. I can turn the truck off and on after the amplifier is off of protect, and it turns on like normal. What could be the cause of this?

maybe the remote line is too weak to power up both amps.

Get you a relay perhaps?

hmm could be.. but i have the remote wire from my HU going to my bass amp then to my highs amp. So i would assume that it wouldn't turn on the second amp on the line first (the highs amp)

i also notice u say u leave the radio on all the time....

Low voltage problem?

noo.. like all i meant was that i don't turn my radio off before i turn my truck off.. but the radio does turn off with the key off.. only reason i said this is because it is weird that i turn my truck on and the sub amp goes into protect, but if i turn my radio off then back on once the truck is running everything works fine

What is the battery voltage after you have left the car set a few days? You can be experiencing a accumulation of a parasitic drain.

Well I never thought to check the voltage because the starter spun the motor over quickly on start up. No lag whatsoever.

But I did just install some bucket seats, and I wired the power to the back of my bass amp.. I disconnect the power seat so now im waiting a few days to go check it out.. This may be the problem.

I would let the car run a little before turning everything on. Also let it sit for 5+ hours and check the voltage on the battery. See if you need a new battery.

So I used my truck today but when I turned started it I looked at the amps. Well they both started off in protect mode like all amps do, then the bass amp went to green then back to protect very quickly. I have more investigating to do with the volt meter, but do you think something is possibly wrong with my amp?

If you've verified that the ground is solid and you are in fact getting a solid 12v minimum to the amplifiers, try disconnecting the speaker wires and the RCA's and see if that effects whether or not the amp starts up normally.

Ah! Thanks, that is a good way to isolate the problem!
