I have a Memphis 16-ST1000D that I've had for a few years now pushing 2 Alpine Type-R 12s (4 Ohm DVC). Well for some reason every now and then it will cut out and the red light on the side (Port.) comes on. I cant find my owners manual so i have no clue what "Port" means. Anyone have any clues?

 

ST model... geez that's old. I can't think of anything of the top of my head except maybe a remote problem.

If you can't get an answer here (though I'm sure Don aka pearl96max will know) you can try here.

I think it's the PROT light [protection]. It's green if everything is okay, red if one or more of the protection circuits has been engaged. Does it go off if you lower the gain?

dh

 

didnt think about that, i will try, but why would it work at the same settings for 4 years but now all of a sudden have a problem?

 

nothing is immune to age and wear & tear. Maybe a heat sink finally vibrated loose.

 

i have the same amp make sure no speaker wire are touching eachothere that could be a problem cuz the same thing happend to me

 

Ground Problem....

 

so basically what we are saying is CHECK ALL ur connections
lol

 

and if it's none of those... look into the fact that something internal rattled loose. And since it's shutting down after awhile, I'd say a heat sink

 

the 4 guage came out of the ring and was held in place by electrical tape so every time i took a corner the right way it would come off the ring. I didnt realize that was it b/c it is grounded under a side panel beside my spare.

 

wow dude thats not smart if it comes out and hits your ground say bye bye to your amp.

 

uh, it was the ground that came out. some how it pulled out of the ring. everything on the amp was perfect. thats why i couldnt figure out what was wrong
