Thread: A 400 watt sub..

  1. #1

    Question A 400 watt sub..

    How loud is a 400 watt RMS sub. Will it be like slightly having bass, loud, or will it shake the car completely.

    And please note thats RMS, anyone can say they have 10000 watt speakers, meanwhile they 100 watts RMS.

    400W RMS!

    400W is f@cking loud! It has the ability to make you deaf!

    It depends on the SPL of the Sub used, as well as the THD of the amplifier used,

    400W RMS could make you deaf if you had 100 SPL speakers,

    but 1000W RMS could sound no louder than a beat box, if you had 82 SPL Speakers...

    With a sub the box that you use also makes a big difference, it must be tuned to the frequency you want to boost. My box is tuned to 40 hertz but with 400w you could go a bit lower, maybe 35?
    And yes, the amp must be good, a 500w mosfet (cause you can bridge it) is what i would use. That combo will shake the car next you!

    I looked at the title of the thread, and thought "A 400W sub? Damn, if that's how loud the sub is, imagine the dom!"

    Maybe I just have a dirty mind...

    400w RMS is plenty.

    A good Type D amp (monoblock or bridged) and a proper install will def. rock your car.

    Nah I doubt it, it will just be more pure and also if its a 15" the bass will just be much smoother, it will make you wanna turn it up more and more!!!

    I got a 12" Rockford Fosgate Punch P2 which is 200W RMS, running off a Rockford monoblock and it pounds!

    400W RMS will be plenty to shake the car, provided it's powered by a decent amp. If you're gonna run a 75W RMS amp into the sub then you're probably wasting your time. But if you run upwards of 200W RMS then it'll crank.

    Also depends a lot on the enclosure, how deep it is, it's length, how large the port is etc.
    Procrastination is like masturbation. It may feel good at first, but when you look at the task at hand, you're actually screwing yourself.
