USX2150 keeps going into protection

[leomon 10+ year member]

Any ideas why my USX2150 goes into protections when gains are set to anything above 2/3 or so? As soon as I push the gains that far the red protection light goes on and I lose my bass.

what ohm load are you running it at

 

[leomon 10+ year member]

DVC 8 ohm Shiva wired in parallel so 4 ohms.

above 2/3 ? Why are you setting your gains so high? What's your input voltage?

If ya mean preouts, it's 4v for the sub. The sub just doesn't put out very much bass with gains set low. Other people have seem to have had to raise their gains fairly high also w/ Alpine HUs.

It may be a voltage problem, most amps will go into protection when they are seeing a voltage that is too low. Take a multimeter and see what kind of voltage reading you get with the system off, then turn it on and see what it reads at.

If you have a significant voltage dip due to the amplifier, I suggest getting your alternator rewound, or getting a higher output alternator.

or it might be something as basic as a loose ground
