Are you tired of asking other people which equipment is best for you?Maybe it's time to sit down and learn the ins and outs of matching an amplifier to yoursubwoofer setup.
There are three key things to consider when pairing an amp and sub.
The total RMS Power of the sub or subwoofers.
The final impedance, known as resistance or ohms, of the subs wired together.
The type of amplifier you wish to run, be it a monoblock, 2-channel, etc.
First, find the total RMS wattage of all the subwoofers within the system.
This is the power rating you want the amplifier to output at the given impedance of the woofers.
Look for amplifiers that have CEA certified power ratings if you want a safe and accuratewattage comparison.
You don’t need to perfectly match up power ratings, it’s ok to run a bit more or lesspower.
Remember, Peak and Max Power ratings should be ignored, these numbers represent quickbursts of power, not sustained musical power.
Next, notice how an amplifier will often function at 1, 2 or 4 ohms and will produce differentwattage output at each impedance.
Depending on how you wire your subs you will need to match the final ohm rating of thesubs to the ohm rating of the amp.
To make things easy, check out our subwoofer wiring guide to help you find the final impedanceof your subwoofer setup.
com/tools/subwoofer-wiring/ Finally, a monoblock amplifier is often thebest type of amplifier to use when powering one or more subwoofers because they are designedto output tons of power at low frequencies.
It’s not uncommon to use a 2-channel amplifier when running low powered woofers, howeverthe wiring is different.
Avoid using a 4-channel amplifier to run subwoofers, they are designed to produce a wide rangeof frequencies and low power which is best suited for car speakers.
For your convenience we have developed a tool to make matching subwoofers and amplifierseasy.
Go to our AmpliFinder amp and sub matching tool, enter the quantity and size of yoursubwoofers and our tool will help you find the right amplifier for your setup.
With these three considerations in mind; Total RMS power, final impedance, and amplifiertype, you will be able to find the right amplifier for your setup at Sonic Electronix.
