its nice to have the reserves when you need it. even though it did not say it and you only have the one sub, the bridged min impedance is 4 ohms, its usually double the min stereo impedance.
i dont know if this is enough power to give you problems with your alt, probably not, but if it is, you may need to add a capacitor to the charging system to provide the extra power when the lows really kick in if you alt's amp rating is not enough. like i said, im not a car stereo guy, so i dont know at what point this will be an issue. i gave a cap to a guy at work because his lights would dim with the bass. i dont remember the value, but it was BIG, came out of the power supply for the radar system. physically bigger than a coke can, probably put a strain on his system just charging that baby up.
