How do u determine if an amp is blown or not?
i have a Hifonics brutas 1000dx amp, 1000 watt RMS. a few months ago i was listening to my music pretty loud and then all of the sudden the sub stopped.
the amp has power, but doesnt play the sub. there is no protect light on.
is it blown or can it be fixed?

Did you check the sub's voice coil to see if it still has continuity? I would think the sub would blow before the amp would. If it is the amp you'd probably be better off buying a new one.

I blew my old school hifonics amp the same way..playing the bass loud and the voice coil on the sub blew and took out the amp at the same time. If not even a pop sound is coming out the sub, then it is probably the amp. Also push down on the sub and see if it fried it. I had some JL audio 10w0's in Camaro for 4 years, then one day no sound.. looked at the fuse and then pushed on the cone of the sub and it was froze up. I have blown about 5 amps so far. I run a old school mtx 2150x(been using since 1998 or 1999 in different setups and the thing is solid. When I first started using it, I tried running a single 12 inch solabaric and fried the sub and amp.. Tried a Boston 12 and same thing.. was tired of replacing them, so decided on 2 10's and has lasted since 2002 with zero issues until I blew the 10w0's(they were around 6 years old and pushed hard for long periods). Now I am running some Memphis Audio 10's and like them even better. I am off topic now..

I would think if your amp blows, you will smell it. I've blown two amps in my day and they the had that burnt electrical smell.

I don't see how a sub blowing up would take the amp with it. When subs blow, the voice coil breaks apart creating a very high impedance which is no harm to the amp at all...correct?

yea the problem is that i put in a new amp right after and the sub was fine. Loud as hell. the amp didnt smell like burnt electrical. the fuse was not blown either. the only problem is that it gets power, but doesnt give out power.

I blew the sub and amp at the same time..happened more than once.. even seen smoke coming out of the sub a few times.
Also, check the ground, I've had bad grounds that appeared to be a bad amp. If your sub is removable take it in the house and hook it up to the stereo and see if it plays.

Well if the fuses are all good and another amp works, then yeah something inside is blown.
