i have 4 dual 2ohm speakers and the amp goes into protection. the voltage is correct and i have a relay for the amp turn on. the subs are the pioneer 3000watt / 1000w rms

How are the speakers wired? What's the total load on the amp? What's the make/model of the amp? What's the voltage at the amp when it shuts down? How did you set your gain? ------------- Support the12volt.com

A quick search shows that his other post was about a differant amp going into protection. similar questions asked, no response from the op... Please answer the questions man. We want to help! ------------- all bad things come in moderation. do not shop at fry's. Get your own log in Omar.

the speakers are wired in series, the total load is 1.6, voltage is between 11 and 12volts. the gain is halfway. the is the powerbass competion 4000w rms

Well they are not in series if you think you have 1.6 ohms. Indeed, 4 DCV 2-ohm speakers cannot be wired for 1.6 ohms, so not sure what you're doing. In any case, turn your gain all the way down then read and follow the "How to set your gain" sticky post. I do not know anything about "Powerbass" amplifiers. Is it rated for a 1-ohm load? And I assume you measured your system voltage with a meter at the amplifier while the system was on? ------------- Support the12volt.com

the amp is a XA4000d which is 1ohm stable. the gain is turned about halfway up

tell us about your power cable.

And tell us more about the 1.6 ohm configuration.

disconnect the speakers and the rcas and turn on the amp. If it goes into protection you have a problem with the amp. If it doesn't go into protection, then connect the rca's. If it goes into protection then there's an issue with the RCA's, shorted out, bad connection at the deck or amp. If it doesn't go into protection then finally connect your subwoofers. Make sure your gain is set to minimum. If at this point the amp goes into protection, then the load is too low and the amp is protecting itself. I could be a defective amplifier if the final impedance is 1 ohm and it's claiming to be 1ohm stable. For kicks a giggles connect one subwoofer with the coils wired in series to give you a 4ohm load. Then connect the 4ohm load to tha amp. If it goes into protection then you definitely have a bad amp. If it doesnt then it probably can't handle the low impedance.

I'm having a similar problem and I don't want start a new thread so here it is.
I had a hifonics brutus 2000w stable at 1ohm pounding away on my 2-15inL7dvc4, and I put it in my friends truck with 4-10incvr dvc2ohm wired up to a 1ohm load but at high volume the amp goes into protection but the amp is cool, I turn the amp off then on again and it starts playing again with no problem.
Well the truck has the original stock battery and even at medium volume the lights dim A LOT ,is it possible the amp is going into protection because of low voltage? Before it had a ssl1500w and 1-12incvr dvc2ohm in a ported box and I know the ssl1500w was not drawing as much power as the brutus is, so and replys will help me out thanks

WELL?

Have you used a meter to verify that the amp is seeing a 1 ohm load? That amp wired into a (.)25 ohm load will do exactly what you are saying it is doing.

Will do tomorrow will post my findings, but the amp stays cool and I have them wired just like the diagram in the subwoofer wiring guide in this site, but I will whip out the meter because befor I put in the brutus I had an auto tek sm1 1000w and it did the same thing and I just thought the amp couldn't handle the 4 -10's.

After checking with my dmm I was getting good current to the amp, but I screwed up and had them wired at .5 ohms., its all good now

If you had it connected to 4 DVC 2Ohm drivers, it was at (.)25 Ohms. It was reading (.)5 because of the resistance of your meter leads. You dodged a bullet.
