We need to know what model of Silverado you have. The standard 1500 series from 2003 calls for a group 78 series battery which is a side post. If that's the case then you should have enough hood clearance to use the PWR-S5-3400 series battery with either a terminal block or the brass SAE post. This battery has more than enough power to start the vehicle and can support up to a 5K wattage stero system.
