so today my amp started going into protect after maybe 10-15 seconds of listening to loud bass. if i have low levels of bass then it doesn't go into protect. it never did this before which is why i am confused.

the amp now goes into protect as soon as i give it a signal to make it turn on. my subs make a light thud, lights dim and then it goes into protect.

i'm thinking the amp is messed up and i want to replace it, so what better time BUT, i'm worried it might be getting dirty power from my alternator, if that's possible?

- the amp is not warm or hot in any way, so i know it's not a thermal issue.
- volt meter says it's getting 14.4 volts.

it's a Sony XM-D9001GTR, not nearly the best i know but all i have.

thoughts? i'm likely going to be replacing the amp but as i said i want to make sure i'm not missing anything and it's the amp that's broken, nothing else.

on a side note, what do you guys thing of Visonik? thinking about buying that one in the for sale section.

 

Could be a damaged voice coil. Test the impedance of the sub and see if it reads correctly.

 

I second that , the visonik is a perty good mid level machine, and all that power for that price how can u go wrong.

 

i removed the subs and it still does that, forgot to mention it in the OP.

EDIT:

i just removed the amp from my car and hooked it up to a spare car battery i have (tested 12.2 volts) then hooked it up to the amp. with no inputs i put 12v to the remote sensor and again it goes right into protect.

 

any other thoughts? just wanting to make sure it was the amp's fault and nothing else in my car.

 

visonik v900hc go for it.........Beat the sh_t out of it.

 

you know my thoughts...lol

 

Blessing in disguise

 

if i had the cash i would gladly buy it, but strapped for it right now, but need my bass so picking it up tomorrow.

thanks guys.
