osamio Posted January 29, 2011 Report Share Posted January 29, 2011 Ok, I had another post about this, but it wasn't specifically about this, so here's the deal. I was tuning my gain with a DMM, with the probes screwed into the terminals, so NO, the outputs did not short! Anyway, I was metering it, and about half way through the tone, the DMM read 0 volts, i look at the amp, and it's protecting. NOW the amp protects with nothing but power, ground, remote. EVEN with just power and ground it protects. I sent the amp to soundstream to get it repaired, hopefully under warranty. Anyway, If i get it fixed or replaced, i don't want it to happen again. I don't know what happened. No one was able to tell me what was wrong with the amp either. One strange thing is that if i place the DMM between the +12v and Remote, it reads 14 volts, as if the remote turn on is shorted to ground. Boon said that the power supply section is probably fried, but WHY did this happen? I can rule out output shorts... Only thing i can say is i'm on a stock batt and stock alt, could the power supply blow from Low voltage? The amp DOES HAVE low voltage, high voltage, output short, and overheat protection.... I will post a pic of my wiring to see if anyone sees something wrong. I'm drawing the conclusion that the Amp was defective, but i'm not hooking up the new one until i'm absolutely positive. Any help would be much appreciated. Anything i didn't cover, just ask.

AMI CUSTOMS Posted January 29, 2011 Report Share Posted January 29, 2011 (edited) You can't rule out voltage drop unless you know what the voltage was at the amp when it happened, big reason why I install a voltage meter when I install an amp in any of my vehicles. But are you sure there wasn't a wire, one strand connecting the 12v+ and remote to make you read 14 volt? If not then who knows why it blew would have to see the inside of it to confirm. Did you get any reading on the DMM or just a zero the whole time, basically were you ever not in protect mode?

Did you get any reading on the DMM or just a zero the whole time, basically were you ever not in protect mode? It was FINE, reading full output as i was tuning it for the first 20 seconds of the tone, then all of the sudden the DMM showed zero, so i lifted the trunk lid and it was in protect. It went into protect in the middle of the tone. and I was just pointing out, after the fact, and after the amp was blown, boon had me check random stuff with the DMM, and one of the things that turned out effed up was the fact that the remote input is shorted to ground, inside the amp. I didn't open the amp cause it's still under warranty, IF they'll warranty whatever happened. I'll know monday or tuesday...

AMI CUSTOMS Posted January 29, 2011 Report Share Posted January 29, 2011 What was your max reading on the DMM? And what amp?

osamio Posted January 29, 2011 Author Report Share Posted January 29, 2011 (edited) What was your max reading on the DMM? And what amp? Soundstream DTR 1700 watt RMS.. and to be honest i don't remember what it read... I know the gain was 4/5 the way up give or take. I was tuning it so that at 3/4 HU volume, where i keep it, the amp would be at 1,100 watts. I don't remember what it was reading when it blew though. 30-50 volts region.

osamio Posted January 29, 2011 Author Report Share Posted January 29, 2011 (edited) If the gain was to high what would happen? It'll clip right? could that blow the amp? cause it's possible it put out more than 1700 watts for too long? would that fry it? **EDIT Sorry if that's a stupid question. i just never thought about it.. i didn't think it WOULD put out more than 1700...but i just did the math, if the DMM ever read 40+ which i think it did, then it could blow right?? cause that's more than 1700 watts..

AMI CUSTOMS Posted January 29, 2011 Report Share Posted January 29, 2011 Probably blew the power supply, and what ohm load would you have been running? If the gain is too high, it will just clip.

AMI CUSTOMS Posted January 29, 2011 Report Share Posted January 29, 2011 (edited) If you got to 40 then that would be 1600 watts, but that has nothing to do with the amp blowing. You should have been looking for around 33.5 volts for 1 ohm, if you where looking for 1100 watts. But I have heard of amps blowing during testing with no load connected to set gains, usually means that something is just defective, weak parts. Clipping wouldn't hurt the amp unless there was load connected.

And yea i know the voltage was too high, i was in the process of adjusting that, i know i should've started at the bottom and worked up... and is it safe to meter the next one the same way? Or should i do something different?
