you should replace it just to be on the safe side

they're pretty cheap i think $20-$30

Check your clutch fan, my car did the exact same thing

yea my car used to overheat..but then u kick it up to about 100 on the highway and it would cool back down. My problem was the headgasket though. I had about 800 watts kicken at 1 ohm with the same guage wire. Didnt u have to get a second battery to power it???my car died every time with the stock battery. But i dont think a system would overheat your car atleast i have never heard that.

No all i had to do was get a better ground because my car would shut off too when i turned it up i dident know if a system could draw too much current from the battery to give some of the other electronics power to operate
