amp in and out of power protect

[masonstephens55]

my ct sounds 1500w rms amp is going to power protect mode whenever it hits hard or low bass. I wired my sub ( avatar 15) to 2 ohms and it is reading 2.4 ohms on a dmm. im not sure if it is just going into power portect because it is trying to use too much power from the amp or if im doing something wrong. I dont think that the sub is blown because it is reading 2.4 ohms. help is needed feel free to ask questions thank you!

i think 9v or 10v but even when i connect it to a 12v battery it goes in and out.

If you're ready that low...your battery might be on its last legs

You need to be able to keep your voltage up to run it...if you're reading 9-10v at your amp now, a smart3 will go into protect that low...you need to find out why you're low before buying a bigger amp imo

okay im confused now, I left it connected for a while and it is now reading 13.8-14.5 volts. everything is working properly now. did something change or could it be a loose connection.

Check the resting voltage of each battery with the vehicle off...it should be around 12v...if one of the battery is under then I'd suggest getting it tested
