JL HD 600 shutting off

[Nerdles1]

Got a JL HD 600 running Focal KX2 components front and Focal flax rear doors. When I crank it up sometimes it shuts off. I can still hear my subs on a separate amp. Had the same amp with morel components and rears lower wattage speakers and it never shut off on me. Wondering why now. I have gains set at half way up. Thinking I’m getting deaf and maybe doesn’t sound as loud as it actually is. Is there any benefit on turning gains up or down does it increase power output or just levels? Could the Focals be soaking up all the wattage?

most likely power related.

Gonna check connections. I do have straight runs right to the battery. Remote wire is connected to pac unit but it is shared by both my amps may try to switch one of the amps to signal sense turn on to try something if I don’t find any thing wiggling wires.

what gauge power wire? and what quality?

Rockford fosgate 1/0 both power and ground to distribution block on amp board then 4gauge to each amp very short runs. Exactly same setup I had before only difference is the focals. Don’t get me wrong it is loud as hell seems like when I really crank up (Van Halen) it shuts off and when I lower the volume a bit it turns back on still very loud. Seems like songs with a lot of mid an high (rock and roll) seems to trigger it.

The amps might be going into over heat protection.

Was thinking that at first but when I turn the volume down just a little bit it comes back on in a few seconds doesn’t seem like it needs to cool down. My guess is these speakers are taking all the wattage the amp is dishing out and amp may be clipping out. Gonna look for a light on amp when I get a chance to see if it goes into Protect/clip this particular amp says it should not do that according to the specs. Neighbors may have to deal with some rock and roll abuse while I look for a problem. Just weird I never had this problem with the lower wattage morels.

Maybe it doesn’t like Van Halen

That would suck

Touch the amps and see if they are hot or not.
