Should amp RMS match sub RMS?
The sub’s RMS watts rating must match the amp’s power range for optimal sound. Find the amp’s power in RMS watts at 4 ohms, 2 ohms, and 1 ohm. Choose the RMS power rating you’d like to achieve. Your sub’s total impedance will be the load impedance (ohms) of that rating.
Can amp RMS be higher than sub?
Should the wattage on my amplifier match the RMS on my subwoofer or should the amplifier be slightly higher than the RMS on the subwoofer? Both are acceptable. I prefer having a higher rms on the amp for more headroom.
How many watts can a 20 amp fuse handle?
A 20-amp breaker can support up to 2,400 watts on a single circuit. The safe maximum for a 20-amp circuit is 1,920 watts, but circuits should not be loaded to more than 80 percent of their maximum capacity.
Will a bigger amp make my subs better?
more power usually will give you more volume, but that really depends on the box type you are using and if its built and tuned correctly for the subs.
How many volts can a 10 amp fuse handle?
2400 Watts / 10 Amps = 240 Volts.
How many volts can a 20 amp circuit handle?
20-amp 120-volt circuit: 20 amps x 120-volts = 2,400 watts.
Are amps or volts stronger?
In plain English: volts (V) equals current (I) times resistance (R). Higher voltage means higher amperage, and thus higher voltage has more potential to kill. …
How many Watts Does a 500 watts RMS AMP have?
The amp is capable of 350 watts RMS x 1 at 4 ohms and 500 watts RMS x 1 at 2 ohms. Let’s say you choose to maximize the amp’s potential and want the system to put out 500 watts RMS. This means your subs have to be wired to form a total impedance of 2 ohms. Two subs on a 500 watts RMS amp will want about 250 watts RMS each.
What kind of amplifier do I need for subwoofers?
Look for an amplifier that can put out power up to the RMS wattage you’ve figured in Step 1, at an impedance load the subs can be wired to form, from Step 2. You have two Alpine Type R SWR-8D4 8″ subwoofers and you want the right amp for them. They are DVC 4-ohm subs rated at 350 watts RMS each.
How many Watts Does a 1 ohm subwoofer need?
Two 350 watts RMS subs together need a total of 700 watts RMS. Using the chart in Step 2, 2 DVC 4-ohm subs can be wired together to form a 1-ohm, a 4-ohm, or a 16-ohm load. The last is too high a load to be practical, so you’ll look for an amp that can put out up to 700 watts RMS into either a 4-ohm load, or a 1-ohm impedance load:
What do you need to know about subwoofer power matching?
Your goal is to get those two variables to match for both the amplifier and the subwoofer. Below, we cover the important basics of power-matching, impedance, and planning for the number of subs you want, and we approach the situation from both sides of the system:
