[QUOTE="winkychevelle, post: 8869549, member: 611804"] Depends on the cooling design of the sub as well as the coil size 2.5inch coil is usually maxed at 1500w with good cooling 2.75inch can usually reach 2kw with good cooling 3inch we have seen 2.5kw 4inch we have seen some quite large numbers. This all bears in mind the the power is clean, the coil is long enough to have the surface e area to dissipate heat, and the sun has the mechanical capability to control the cone. Generally you only gain 3db everytime you double power. This varies due to vehicle acoustics, impedance shift and box rise but If you have 140db 1000w 143db 2000w 146db 4000w 149db 8000w You can see how power can destroy a sub long before the 10db you need to by ear double the volume. 3db is considered the minimum change in volume we can hear in the bass region.
