Frequently Asked Questions

Is it OK to put AMP on sub box?

It is generally not recommended because all the shaking and vibrations could cause the dislocation of the inner components of the amp. It’s better to find a different spot somewhere around the back seats to mount the amp.

What is the best amp for 2 12 subs?

The RIOT 1100 Watts, Mosfet is generally considered one of the best amps from 2 12-inch subs. Designed to specifically feed your subs, it’s equipped with bass boost control and is easy to install. Moreover, it’s from the BOSS team which makes some of the best-selling audio products.

How big of a box do I need for a 12 sub?

For a 12-inch sub box you need the dimensions 23.62” x 13.78” x 16.86”. These are the ideal measurements. You will also have to keep in mind that there is sufficient room along the clearances of the sub.

How many amps does a subwoofer use?

If we use ohm’s law and take 120V as the standard electricity board rated single phase voltage for domestic switchboards, the amp rating of a typical 1000W power subwoofer would be 11 Amps RMS or peak 15 Amps.

What hits harder 2ohm or 4ohm?

Low resistance subwoofers produce louder sounds than high resistance subwoofers. So, 2-ohm subwoofers are louder than 4-ohm subwoofers. However, the 2-ohm subwoofer most likely will have poorer sound quality owing to the power consumption.

Does a bigger box make subs louder?

A bigger enclosure box will make a sub sound higher than the tuning frequency but the other notes will not be much louder. Also, enclosing a sub in a larger box puts pressure on it that might exceed its mechanical capability and therefore, there can be damage. It’s not recommended.


It is important that you select a subwoofer and amp package that suits your taste of sound and bass. Electronics such as subs have a tendency to go faulty, always look for warranty. Pay attention to the physical size of the subs and the quality of the amp wiring, they’re crucial in extracting the best performance. Make sure you’re investing the right amount of money as per your needs.
