So You Build And Install A Car Audio

system into a vehicle and you turn it on for the first time and you’re just not impressed The subwoofer bass performance is lacking in the mid-bass from our speakers is just not as punchy as what we were hoping for if you’ve ever been in this position. It is not a good feeling but not to worry my friend because in this video we’re going to talk about four different mistakes that are often made that lead to poor bass performance and at the end of the video. I’m also gonna give you some bonus tips for how you can add more bass once you make sure that you didn’t make any of those four mistakes hey what’s going on guys welcome to car audio fabrication. My My name is Mark and I’d like to welcome you to this channel where we do car audio reviews and build dog videos and lessons like this video. Because I truly believe that when we design, build and install a car audio system the correct way we can really experience and feel the music rather than just listening to it so mistake number one wiring issues.

Its Really Important That When Were

finishing up our install and making the connections from the wires to the actual speakers, we want to double check and make sure that similar speakers have these same polarity. In other words, let’s say that we have our six and a half inch speakers up front that are gonna be providing our mid-bass. We want to make sure that both of those six and a half inch speakers on each side have the positive wire on. The positive terminal and negative on the negative terminal Now the same goes for our subwoofers. If we have multiple subwoofers, we want to make sure that they are also wired in correct polarity.

The Reason For This Is If You

have one speaker that is going out while the other one is coming in the speakers are going to be working against each other. They’re not going to be compressing air and building upon it to create acoustical energy. Now maybe you have poor bass performance and you know for a fact that you’ve connected the correct wires to each terminal on the speakers. Something else that you want to verify is you want to make sure that wherever you’re getting that signal from that it is wired with the correct polarity. As well as an example, say that you installed a line output converter and that you tapped.

In To The Rear Speakers Of The

vehicle, you would want to make sure that would that line output converter that you connected the positive leads to the positive wires and didn’t have them opposite from the left to right side otherwise you could have polarity issues. Let’s say that you check the speaker terminals you know they’re correct and you’ve checked your wiring on something like an integration piece like a line output converter and you know it’s correct there’s still one more thing that could be wrong. The speaker may be wired incorrectly from the factory. This seems crazy but I’ve actually seen it happen quite often where the terminals the positive and negative terminals on the speaker will just be labeled incorrectly. So ultimately the best way to really check polarity is you can use a polarity test tool.

This Tool That Im Showing On Screen Allows.

you to simply hold the device close to the speakers and it fires off a series of pulses so what you can do is. You can use this little device to check all your different speakers and make sure that they are all wired correctly in the same polarity a link to that device is down in the video description. So let’s say that you check all that you know that everything is good to go polarity wise mistake number two that can be made is phase issues. A common example setup that we can use for a car audio system is something where we had a subwoofer playing frequencies from let’s say 20 Hertz all the way up to 80 Hertz and then let’s say from 80 Hertz.

We Hand It Off To A

six-and a half inch component. Issues with phase can arise in that handoff transition. from the subwoofer to the speaker. This is because the subwoofer and the speaker will be located in different locations within your vehicle. Let’s say that both the subwoofer and the speaker are playing 80 Hertz.

Our Goal Is To Be At A Listening

position that those waves work together, not that they work against each other and cancel each other out. So there’s a couple quick solutions to see if you’re having Faye’s issues. One of the first and easiest solutions is to actually flip the polarity on the subwoofer or on your speakers. Generally it’s going to be easier to just flip it on the subwoofer because a lot of subwoofer amplifiers have what they call a phase switch where you can flip it 180 degrees out of phase now Yes. At the beginning of the video, I talked about having every wired in the correct polarity, but it’s only important for like speakers.

In Other Words, The Subwoofer And The Speakers

don’t necessarily have to be wired in the same polarity. It’s okay to have them in different polarity because it might help correct your phase issues Because when you switch the subwoofer 180 degrees out of phase, it might correct the issues that you’re experiencing with lack of the base. Another solution is you can move the subwoofer around within the vehicle before you permanently install it in order to test and make sure that you don’t have any phase cancellation issues Ultimately, though, one of the best solutions is to have a digital signal processor, where you can actually delay the front speakers, so that the sound that is furthest from you at the subwoofer when that finally. arrives to you you can delay the front speakers to then deliver that sound from them At the same time. This functionality of a digital signal processor is called time alignment and ultimately it’s going to be the best solution for you.

But A Uk Can Be Expensive,

so it might be easier to try flipping the polarity on the subwoofer or moving the subwoofer box around first. If you’d like to check out one of my other videos that I did it more in detail on what a UK is you can check out this video here on screen now mistake number three subwoofer enclosure type and construction along with installation of speakers. Let’s say as an example that you have a sealed subwoofer box installed in your vehicle and you find that you’re not quite getting enough bass you might want to consider another subwoofer box type you’ll. find that a ported subwoofer box will generally have more output, but it’s important to consider that every subwoofer has a different range of variables that affect how it actually responds and plays music. As an example, let’s say that we take a ported subwoofer enclosure.

Lets Just Say Its One Cubic Feet

tuned to 32 Hertz and let’s say that we put two different 10-inch subwoofers in it we know that we’re gonna get different sound from each of these two different subwoofers. This is why prior to building and installing our subwoofer box. We should consider what the frequency response will look like for the subwoofer that will be using now. It’s also very important for our base performance to consider the volume that is required for a subwoofer. If you install a large subwoofer into a space that is far too small for it.

The Subwoofer.

Isn’t going to perform to its optimal capability and one of my previous videos I talked about how you can estimate what your box volume will actually be after all displacements for something like a ported subwoofer box. You can check that out here on screen now let’s say that you’re confident within your subwoofer box type something else that you’re gonna want to consider is the construction of the subwoofer box. One of the biggest issues that I always see is when a subwoofer box isn’t sealed well and this goes for ported subwoofer enclosures. Also the only way the air should be able to come in and out of a subwoofer box is through a pore and obviously if it’s a sealed box it shouldn’t be able to come in and out at all.

Its Really Important To Make Sure During

the construction phase that all of your. cuts are extremely straight and accurate and if they’re not it’s important that when you’re actually building the box that you use plenty of caulk in order to seal up all of the corners next. It’s important to make sure that your box is properly braced if you have a very powerful subwoofer, but then a box where all of the walls of the box can easily compress and flex. Then you’re going to lose out on a lot of acoustical energy and that means that you’re losing out on output to alleviate this problem you should have bracing another important thing to verify is more on the installation side of subwoofer Boxes you want to make sure that they are fully secured within the vehicle. Properly securing the box to the vehicle makes the box much more stout and it makes it so that you’re not losing any of.

That Acoustic Energy Which Means Again

more output now I’m the speaker side of things and getting good mid bass. It’s also equally important that we consider our installation something else that’s really nice to add is these foam rings. These rings help to bridge the gap so that it directs all of the sound through the hole within your door panel. The reason that’s important is if you have the sound bouncing around inside the door panel. It can actually cancel out a lot of your mid-bass performance for a full video about that and making custom speaker adapters in order to make sure that you get the best mid-bass performance again video on screen Now Finally, mistake number four poor system design it’s really important that when we select all the different gear for our car audio build that we properly match the different items.

Your Amplifiers Output Power And Watts

UK should closely match the capability of the subwoofer that you’re purchasing as an example. Let’s say that you’re using a subwoofer that is super beefy it’s super strong. I can handle a ton of power and you’re using just a moderately powered amplifier. You’re not going to be powering that subwoofer to its full potential and actually the amplifier is gonna have a hard time moving this big beefy subwoofer, so you’re gonna. have reduced performance compared to if you just had a matching subwoofer now let’s say you have an amplifier that’s much more powerful than what the subwoofer can handle.

• performance lacking mid bass speakers

Although Youre Gonna Be Able To Power The

subwoofer to its full potential. You’re leaving opportunity within your amplifier. You could have had more output something else that often gets ignored is you have to remember that it takes power to make power. You can’t buy a 10,000 watt UK amplifier and install it into a little car something like a Honda Civic without upgrading the electrical system.

Its Important To Have A Big

enough power plant within your system, and in this case that’s the alternator we want to look into something like an upgraded aftermarket alternator if we’re going to be using a huge amplifier. We also want to make sure that our power delivery system The wires is. also upgraded.
