Default Low power on windows and starter

Ever since I got the car, it feels like it has low power. The windows do go up and down but it seems weak. My mom's old bucket's windows go up flawlessly with way more electrical power.

Same thing when I start the car. It's like the starter doesn't have much power.

Is this normal for the 2004 WRX?

Have you done a test on the battery to see if it has enough amperage? Sometimes batteries can show over 12 volts and have virtually no amps. Or if it's a particularly cheap battery in the first place. Check body grounds too and consider adding more. I've used 4 gauge wire to add two or three extra grounds to every subaru I've ever owned. Seemed to always make the lights brighter and radio louder.

I had the same issue on my 2014 WRX! which you wouldn't think would happen only a year after owning but dealer replaced motor snd I changed the battery to an OPTIMA 8040-218 D35 and everything works much better. Could be anything though...alternator, battery, motor, too thick of window tint,.. factory window motors aren't known for lasting too long. I got the Optima battery as I will be installing multiple stereo amps later and will need all the juice possible. Anyway hope you figure it out and it doesn't happen again
