I was coming home from work beatin' //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif , all of a sudden the bass goes out!!!

I'm like FUUUUUUUUU!!!!!!! So I shut the HU off. Then after a minute, I turn it back on. I turn the volume up and the bass is considerably low in volume (as if the gain was all the way down), turn it up more and it goes out again!!!

I park in the drive way and open the trunk. The amp is pretty COLD. Not hot at all. No hot wires, nothing like that. WTF is going on???? Is this protect mode? Why is it in protect mode? What happened?

The amp is a PPI black ice bk1800.

Amplifier Protection Mode Troubleshooting Hope that helps? I just googled this for you quickly and found that. Any questions you have, I definitely won't be able to answer good luck.

Check all your connections. Measure voltage back there too. Something might have rattled loose, and it's possible its getting real low voltage. Or maybe you're getting a short somewhere.

Well what happened definitely isn't good.. Either you blew something in the amp or you fried your voice coil on your sub. Get a DMM check your voltage and check the ohm load on your subwoofer. If you reading in the megaohms you blew the sub. If the sub load is normal something in the amp went bad. I suggest not running anything until you check these things. It's a great possibility you can save the amp if it is having issue by sending it out to ampmedics. Don't try to run it without doing the simple checks first because you can cause more damage than the amp is worth.

Is it possible that something can be damaged in the amp yet still work, though not like it's supposed to? Could that explain the sound being so low after turning it on again?

**** I hope it's the subs that are fucked........I got them for free, lol.

I guess your name shouldnt be beatin' anymore. //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

But like others said, it might be your subs. Check the coils with a digital multimeter. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Yes when a couple transistors burned up the same thing happened to me. Check subs first.

If the subs blew, is it normal that they can still play? Because when I turned the HU back on when I was driving, the subs could still be heard, although at low volume due to the way the amp was acting. I didn't hear any distortion either.

Also, can I check the coils using the box terminals? Or do I have to take out the subs?

edit: The instruction manual says the amp has "overload" protection. Does that mean the amp will shut down if the impedence is too high?

My subs are two radio shack 15's. They are 8ohms each for a final load of 4ohms. They are rated 150wrms each, but I'm routinely doing 300wrms in each. Can the impedence rise caused by very hot voice coils cause an amp to shut down?

Testing is really the way to get a good answer.

Yes you can test the outside terminals and yes they will still play very low volumes if they are burnt up.

I got into the car and checked all the wiring. Looked good. I even took out the HU to see the rem wire, maybe it got loose? I noticed the electrical tape was coming off so I took that off and put on a new strip.

Then I turned the HU on and played a song a low volume. I noticed the right sub is playing but not the left sub.

I shut everything off and went to the trunk to try something. I pushed in the right sub, no problem. I pushed in the left sub.....*SCRAAATCH*. I took out both subs and did a DMM impendence check. The good sub read 8.6ohms, which is normal because they are 8ohm each. The messed up sub wouldn't even give the DMM a reading.

Did I find the problem or is there possibly more? I'm thinking this is what the "overload" protection on this amp is. If one sub blows and all of a sudden the amp is only seeing an 8+ ohm load at high volume, the amp will shut itself down..........right?

The sub is blown, hence why it isn't reading an impedance on the DMM. The amp isn't seeing the correct ohm load. Get new subs
