Default Sundown-2500 keeps shutting off

I have a Sundown saz-2500d it keeps shutting off at higher volume. I have 4 skar vvx 10 dual 2ohm.The speakers are ran at 1 ohm to the amp. I can listen at medium volume. When I go louder it goes into protect mode.

Also the Power wire is getting a little warm <not burning hot just warm to the touch> at the fuse terminal.

If anyone knows what could be going on please help me out.
Thanks

Sounds like a loose connection. Double, triple, and quadruple check the power and ground at every connection. If using a crimp connector and looseness in it will cause heat and a loss of power that could turn off an amp.

Ground for the battery is to the frame. Ground for the amp is to the frame with nice bolts paint has been scraped off.I have a Sundown 100.4 basically on the same ground location It never shuts off.

The amp is used has been fixed by http://www.db-r.com/

What's voltage at the amp? If the wire is warm near a fuse point you need to pull all of that apart and check the connections. Either a poor crimp/solder, loose bolt, or fuse issue.

Definitely want to monitor voltage at amp's input, see what it's doing.

Recheck with multi- meter to make sure you're at 1 ohm

The warm power wire is a little concerning; 1/0 wire should not be warm at all with that amplifier.
