Ohms are a measure of resistance and have nothing to do with how loud a sub is.

Never understood the appeal of those boom box, resonance cars.

more or less ohms doesnt mean how loud the sub is, take a $5 8 ohm sub and a $500 8 ohm sub and im willing to bet the $500 one is louder. You base what ohm configuration to pick based on your amplifier. Is your amp 1 ohm stable? 1/2 ohm stable? Once you figure that out then you can pick the config on your subs.

Two dual voice coil 2 ohm subs can be wired down to 1/2 ohm,
Two dual voice coil 4 ohm subs can be wired down to 1 ohm,
Two duel voice coil 8 ohm subs can be wired down to 2 ohm, and so on.

Use this to figure out what you need to do:

As far as loud, its all relative in a car, you could have window shattering loud or you could have nice, clean loud that you can actually still hear the music. If you are looking to just make a statement with how loud your car bass is, I reccommend a for sale sign for your car and ride a bicycle. Save the loud for your house when it is just you and your family around. No need to piss other people off.
