    Silicone Heater, not getting hot enoough

    I have a 300x300 silicone heater connected via SSR to my Rumba
    running on 12v 30A power supply

    when i turn on the heat it maxes out at around 52 degrees..
    the heater has two Red Power cables.. how do i know which is the Positive and negative?
    does it matter?

    running 12GA wire to power it.

    Polarity doesn't matter for a heater.

    Most likely you have a voltage drop, somewhere. If you got a cheap SSR, then that's most likely the problem. If your controller can handle it, increase the voltage output of the power supply.

    There is no option to change output voltage. just 12v output
    it is a cheap SSR
