Everything To Know About Car Subwoofers

Subwoofers. The bass. The loudness. The glory. The most obnoxious component in your system, and also, one of the most important.

If you have study my write-up about speakers, you happen to be up to speed. If you have not (and don’t know anything about speakers or subwoofers), study it right here.

Subwoofers reproduce the lowest frequencies of the audio spectrum, AKA bass. They are essential to both SQ and SPL systems, but for different factors. Let’s get a look now…

For SQ systems: Efficiently reproduce the lowest frequencies making the music sound total and effective. Instruments that play decrease frequencies this kind of as organs, drums and synthesizers will sound more reasonable and effective with a subwoofer set up.

For SPL systems: For the reason that subwoofers are loud, they are the preferred speaker to make a full lotta noise.

Also, mainly because our ears are much less sensitive to decrease frequencies we need to have the additional bass for the system to sound balanced.

So, what do I have to look for to obtain a terrific woofer? I’ll tell you!  For a full review, go to

Power Managing:

Just like with every single other component in a stereo system, power managing is significant for subwoofers as properly. Earlier, in my write-up about speakers, I talked about how you can send more power to them to boost their volume, but decrease the distortion. The identical is genuine of subwoofers, but be cautious! Due to the fact decrease frequency distortion is tougher to perceive, it can be easy to overdo it, and blow your subwoofers. Anyway, with that explained, it is sensible to acquire an amp that can put out precisely what your subwoofers are developed to get, but get it easy!


Subwoofers come in many sizes, but the most common are 8″, 10″, twelve”, and 15″. This is possibly also mentioned in metric for the european manufacturers. As you can picture, the greater woofers are the ones that will play louder and play decrease. Of program, the smaller ones are more musical, more precise, and sound “tighter”. What size you like normally has to do with your very own preferences, as properly as set up concerns. Recall! 18″ subwoofers don’t just fit anywhere!


SVC: Single voice coil

This signifies that the speaker has only one voice coil. In other words, only one input.

DVC: Dual voice coil

This signifies that the speaker has two voice coils, or two inputs.

Ummmmmmm, okay. Why does it matter?

I could go into specifics right here, but I know you don’t really care. Generally, it boils down to this: With a DVC subwoofer, there are more set up selections. Appear at it this way, a DVC “looks” like two subwoofers to your amplifier. With some nifty wiring tricks (called series and parallel), you can hook up many subwoofers to a single amp–even if the amp is a “mono” or a two channel amp. In addition, you can manipulate how many ohms the amp has to push. If you have an amp that is stable to a half ohm (like some outdated college Orion HCCA amps), you could potentially hook up 4-8 woofers to a single channel! Think about the noise you could make!

Some words about Speaker Boxes:

Speaker boxes are essential to most subwoofers. In other words, contemplate a subwoofer’s box just as significant as the subwoofer itself. Why? For the reason that most subwoofers need to have a box to operate effectively, sound fantastic, and not damage themselves. Subwoofers that don’t need to have a box are called “free of charge air” or “infinite baffle” subwoofers.

Like I explained, most subwoofers need to have a box. So, let us talk about boxes!

Very first, what kinds of speaker boxes are there?

Sealed: The easiest kind. Fundamentally, a sealed box is a box wherever the inside and outside are not linked. There are no holes, and care is taken to assure that the box is wholly sealed.

Sensitivity: This phrase signifies precisely what you believe it signifies. In brief, a subwoofer with higher sensitivty will be louder than a subwoofer with decrease sensitivty when they are hooked up to the identical amp. The spec is measured in db.

Frequency response: You obviously want a subwoofer than can deal with a broad array of frequencies. On the other hand, the subwoofer does the most work underneath 100hz. If the subwoofer plays all the way down to 20hz, you know you have acquired a terrific sub. The fantastic news is that even if it isn’t going to go that low, most music isn’t going to either. Sooooo, you are going to even now be fine. I would say the it can be more significant to have a low-enjoying sub in systems with DVD players and 5.1 sound. Also, frequency response varies depending on the box that the subwoofer is set up in. Ummmm, so with this in thoughts, just select a subwoofer that will deal with the power, and sound how you want it to.

Cone Material: When it comes to subwoofers, this is basically a very significant point to shell out attention to. For the reason that subwoofers are massive and effective, you need to have a cone material that can withstand lots and lots of abuse. I personally am a massive fan of metals this kind of as alluminum. This is mainly because aluminum is light and stiff, and likewise, produces really tight and musical sounding bass. I know that many subwoofer makers use exotic sounding products for their subwoofers, which tends to make it challenging to figure out which material is the best.

Surround material: Here’s my suggestions: Usually get a subwoofer with a rubber surround. Rubber holds up the best in the auto atmosphere.

Impedence: Measured in Ohms, this spec tells you how much resistance the speaker presents to your amp. Too much, and you get no volume, also little, and your subwoofer will fry your amp! This spec will help you make your mind up which amp to hook up to your subwoofer, irrespective of whether you want to bridge your amp, and irrespective of whether you want to wire multiple subs into parallel or series. Also, subwoofers in some cases have more than one voice coil (aka DVC). This signifies that the subwoofer will have two inputs, each with the identical impedance. Subwoofers with dual voice coils are more versatile to set up, especially in multiple woofer systems.

A primary subwoofer set up is pretty easy. If you acquire a pre-fab sub box, mount the subs and power them, you happen to be going to get fantastic bass. To set up professionally, and realize the best sound, much arranging and work should go into the full method. This is a circumstance wherever if you don’t really feel confident in your ability to build a box, tune it, and hook it up, you should go to a car audio store, and have them do it for you. This can be comparatively cheap, or very high-priced.

If you are arranging on performing the set up on your own, but lack the box setting up abilities, you can acquire a pre-fab box. I would also strongly advocate an EQ gadget to fine tune the bass. This will help you overcome road noise (which ruins bass), and also minimize back on “boominess” and “muddiness”. In the finish, this route is the best compromise in between a custom box and a pre-fab box. You are going to get terrific sound, and conserve income!
