Well i got a box with these crappy subs i think and i need to know how to hook it up. i want to amp the box and bypass the factory amp and use the headunit to power all my door speakers

we need more information.
what kind of subs are they? are they dual voice coil or single voice coil? how may ohms is each coil (1, 2,4, 6, etc..)? and if you have the factory headunit, you cant bypass the amp, you will get no sound. if you have an aftermarket headunit, get a bypass harness from crutchfield or circuit city.
