I have a budget minded setup that i recently installed. Amp is a Power Acoustik 2ohm stable 2 channel amp that I have bridged. Subs are also Power Acoustik DVC 2ohm subs, 2 subs total. I have the subs wired in series/parallel as shown in the pic below. Everytime I turn the sound louder and/or increase base via the remote bass control, after about 30 seconds the red protection led on the side of the amp turns on, and the amp shuts down. If i turn the car off and turn it back on the amp works again.

I don't think the amp is overheating since this happens even after the car has cooled off at night and started in the morning. I'm leaning towards incorrectly wired speakers/wrong impedance. Currently the subs are wired first in series to have 4ohm per sub, and then in parallel to have 2ohm mono bridged at the amp. Would it make a difference to wire the subs first in parallel, so that each sub is 1ohm, and then in series to have 2ohms. I'm going to try running the amp using both channels at 4ohms instead of bridging at 2ohms, next to see if this continues. Any other ideas?
