Subwoofer cutting off and restarting at high volumes

[kylej 10+ year member]

So I have a Rockford Fosgate Prime R1000d and a 12" Alpine Type X subwoofer. When I put the subs to a high volume it will cut off but then after a few seconds come back on. Is this mean the amp is above peak output? Or what is the deal.

Sounds like you are clipping the amp and it's going into protect mode. Should turn your gains down.

Could be a few things,

Could be a loose connection from the amp to the subs,

Could be a loose connection on the amps +/-/R

Could be that the impedance goes to low at certain freqs and sets the amp into protect.

Check all of your connections.

From my experience, it sounds like your amp is going into protect mode. Likely from lack of electrical support, and poorly set gains.

I noticed that also when the amp cut off the sub that the overhead light also cuts off. And then comes back on when the amp does. Could I be drawing too much power from my stock battery or something? The battery doesn't drain quick if the car isn't on or anything just cuts off a few electrical components.

most likely this, it was happening with my set up about 2 weeks back and when i went to look things over the nut that holds down the line fuse on one of the power lines to the amp had shaken loose. tightened it up and has never happened since.
