Autotek MM4000.1 going into protect... wtf

disconnect all the wires from the amp and wait 5+min to give the amp reset its self it has worked for me

I thought he'd already tried this?

If not, then yeah give it a power cycle. Just unplug all power / ground / everything for a few minutes, then hook it all back up as if you were installing it new again and hope this resets the amp's internals and no protect light comes on. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

i think he only disconnected the subs

dam man, are you sending it somewhere to get it fixed? i might contact dbr on mine.

OK HOLDON!!!

DONT SELL IT ALL YET!

If its staying in protect, it could be a blown channel, which is not terribly expensive to have fixed!!!

Amp Repair Center is where I sent mine off to, should have em back within a week..

Ive gone through everything from, bad grounds, to maybe a power wire gettn cut n grounding out..

I cant figure it out-- Were both running batcaps, maybe their beatn the shit outta our amps!

I tried, i'll give it another shot tho. I pulled it completely out and then only connected the power and remote turn on after 10 minutes of it not being connected. idk //content.invisioncic.com/y282845/emoticons/verymad.gif.3f39c5c2fd57527b671fad3efdfac756.gif

more than likely you blew something up in the amp. have you taken the cover off to see if there are any burn marks or damage to the board?

yes i did, cannot physically see anything, everything looks in tact/ non burnt

all the legs are ok on the fets, nothing burnt. I emailed amprepaircenter.com, gonna see what they can do. DB-R is telling me it might be the "PCB". not sure what that is

gotta go to work now //content.invisioncic.com/y282845/emoticons/verymad.gif.3f39c5c2fd57527b671fad3efdfac756.gif

Does anyone know what the PCB is? or if it can be repaired?

 

[x2o 10+ year member]

I'm not sure what it refers to in the world of amplifiers, but when I think of PCB I think of printed circuit boards. Which would need to be replaced if it is the circuit board that's bad //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

I had a resistor fall off internally on mine before, did the same thing. was a cheap fix.

See if you hear anything fall internally if you flip it over.

Hey bro, check that ohm load on each sub for a blown coil??

Scott from amprepaircenter.com emailed back saying it is usually a blown channel, i'll see if something is loose/if i can fix it. if not, its probably going to be shipped there i guess, or sold AS IS //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
