The subs are 450 watts rms total. I don’t know how much bass you’re looking for, but if you’re asking about shaking cars, they’re definitely not going to add that much. Don’t get me wrong, they add enough bass that you can feel when the subs hit, even at lower volumes. When I put the volume up, it does vibrate some stuff in the cab, and when I look in the rearview mirror, it looks like I’m doing some off-roading. But they are not ridiculously loud to the point that it shakes anything outside, or sets alarms off (that’s what my exhaust cutout is for).
