I would go with disturbedfuel15's suggestion, try using an inline 40 amp fuse. It is possible that with the 80 amp fuse on the power wire, the amp is seeing a current that is less than 80 amps but, greater than 40 amps.

The fuse for the power wire should never be greater than the total fuse rating of the amp. The amp is not supposed to receive more than a 40 amp current, however, your inline fuse will allow 80 amps to flow to the amp. The inline fuse is meant to protect your power wire and also your amp.

The input voltage measured with the DMM set to ACV 200 is 28.8 volts. The input voltage measured with the DMM set to DCV 200 is 13.3 volts. The voltage measured at the speaker output does not increase very much until the gain is more than half way to the maximum.

Is there any kind of break-in period for new amplifiers?

I would try taking the subs out of the box and checking the terminal cup connection that goes to the voice coils. I had a similar experience where my sub would hit hard and the air inside the box would cause it to loose connectivity.

Regardless of where I measure speaker output voltage, the readings are all the same. I measured the output for one set of positives and negatives and the output for the other set of positives and negatives. The results were the same exact voltage. I have also measured the voltage for one...

The settings of the amp are: subsonic filter: on LPF: 90Hz The test tone is 0dB @ 50Hz. I got all of my test tones from http://www.realmofexcursion.com.

One other thing that I am unsure about is the way my speaker wire is going from the box to the amp. I am currently using a pre-fab box that has 2 terminal cups. The voice coils are wired to 1 ohm. The amp has (2) positives and (2) negatives; they parallel internally. I have each sub positive...

I just tested the voltage with the following: bass: 0 BBE: off subwoofer: +15 sub sys 1 The max voltage was 23.9 volts with the gain set to max and bass boost on. The amp has (3) 40 amp fuses.

I do not know for sure that the fuse in the DMM is working. Having the DMM set on ACV 200, the readings of a 9V battery are 20.0. Having the DMM set on DCV 20, the readings are 9.47.

I have checked the fuse and the battery in the DMM and both are properly working. I tried to turn up the volume past what I would normally set the maximum volume to and I didn't get much of a change. I have checked the RCA connection to the back of the HU and everything is plugged in. I have...

I am having a great deal of difficulty when trying to set my gain using a DMM. I have a Directed D2400 powering (2) 4 ohm DVC Kicker CVR. I am planning on wiring the subs to a 1 ohm load. Each sub RMS is 400 watts; a total of 800 watts needed to power both. When using the formula to...
