Can a subwoofer be used without an amplifier?
In nearly all cases, the answer is yes. Unless you have a system in your car or boat that is already powering a subwoofer, you'll need to find an amplifier that will power your sub. Your head unit will typically provide a low-power signal (RCA output) that can be used for an amplifier to power your subwoofer.
Do 8 inch subs sound good?
An 8" subwoofer is going to give you tight, clean bass. There are some 8-inch subwoofers that sound really nice and some might even compare them to a lower end 10" or 12", but generally speaking, an 8 subwoofer is going to give you nice, affordable, clean bass.
Why do subwoofers need an amp?
Why Do Subwoofers Need an Amp? Subwoofers are designed to reproduce low-frequency sounds. This takes a lot of power. In designs where the subwoofer came as a part of a larger sound system, it will be properly optimized to work with the rest of the setup without showing any distortions as a result of inadequate power.
Do subwoofers need power?
A subwoofer (sub) is speaker, that is dedicated to the reproduction of low-pitched audio frequencies most commonly referred to as bass. Passive Sub: Passive subs are called passive because they need to be powered by an external amplifier or Audio/Video (A/V) receiver . This is similar to traditional speakers.
How much space does an 8 subwoofer need?
According to the JL Audio website, the recommended volume space for a 12-inch subwoofer is 1.25 cubic feet. For a 10-inch woofer, the volume recommendation is 0.625 cubic feet, and the recommendation for an eight-inch speaker is 0.375 cubic feet.
What size subwoofer hits hardest?
Do 10 or 12 subs hit harder? Given enough power, two 10″ subs will sound a little clearer and punch harder due to their greater cone surface area. The single 12″ sub, on the other hand, may sound somewhat deeper. 12 inch subwoofers are ideal for people who want more bass than smaller 10 inch subs.
What power subwoofer do I need?
How many watts for subwoofer? As a general rule of thumb, it is best to go with at least 300 watts in order to get enough power for your subwoofer. You can always add more speakers if you want, but it is important that the amp matches the speaker system as well.
What size amp do I need?
Generally you should pick an amplifier that can deliver power equal to twice the speaker's program/continuous power rating. This means that a speaker with a “nominal impedance” of 8 ohms and a program rating of 350 watts will require an amplifier that can produce 700 watts into an 8 ohm load.
