Last Christmas i bought a sound system for my Camaro. 2 JL Audio speakers (front), 2 Infinity speakers (rear), JVC Arsenal headunit, 2 12" Kicker CompVR subwoofers. It's run from the battery to a capacitor to the amp which is 1100watts. If i don't turn my head unit off before i turn the car off, when i come back to turn my car on, the car won't start. So i have to turn my head unit off before i turn the car off. Whats the reason why this is happening?
