Subs cutting in and out.

I don't know where ya'll are getting 4 amps from but he said he has 4 subs, and then says one pair is fine and the other is acting up. So if he's got four subs and saying there wired to one ohm per pair, then it looks to me like he's got 4 D4 subs on two amps.

Because he wrote:

I'm running 4 subs each on separate amps

Makes me think he had 4 amps.

but then he talked about setting the gains on both amps. So maybe op just needs to give us a list of what he's working with to verify all of this.

So what joe said still works, find out what is common between the 2 failing amps that is different than the other two amps.

That's what I tried at first. But I cannot find any difference. Both Amps are putting out 42.3 volts,and every connection is secure. I'm going to swap the Subs and amp and see if the problem continues on the same side; if it does continue then it's my subs. If it stops and transfers to the opposite side then it's my amp. Im not exactly sure what It would be on the amp causing this proble tho.

Who knows what it is but is not a good idea to mount amps directly on the box.

I'm going to try and stack some more rubber under the amp mounts on each one. Its possible that vibration killed it

If you haven't yet.check the connections on the subs. My brother was having that issue and thought he needed bet yer grounds.. Checked the connections and one was lose causing amp to not send signal or going to protect

Grounding was also what I thought at first,but ground is good and so aren't my connections. Thanks for the suggestion
