Driver Safety: Driving & Parking Assist Systems

You Need Some Assistance

Disclaimer: This is not a crash course in drivers ed.  This is a wake-up call to all you distracted and accident-prone drivers out there!

In today’s modern world, there are countless distractions that can cause injury to yourself and others. I can attest to this personally seeing as I have carelessly totaled a car and watching your wheel fly off is not a good start to anyone’s day. With that being said, there are lots of ways to prevent you from being ignorant like me.  There are tons of aftermarket parking and driving assist systems that could save your car from utter destruction or even your life.

Power Acoustik DRIVE ALERT

In recent studies it has been found that the average driver has an accident about every 10 years.  However, if you live in a busy city this can be cut in half to about 5 years! A major cause of accidents is negligence of checking your blind spots.  A way of drastically reducing this danger is by purchasing a system such as the GOSHERS BSDS3016.  This is a blind spot detection system that will give you audible and visual warnings if you try to change lanes when there is someone present in your blind spot.  It is a universal system so it can be put on any vehicle such as commercial trucks, RVs, fleet vehicles, or a standard automobile. Another noteworthy prevention system is the 3-in-1 Power Acoustik DRIVE ALERT.  This is a unique system that offers front collision warning, lane departure warning and a black-box recorder which records audio and video prior to a collision to aid in insurance or police investigation.

We also offer an abundance of rear and front parking sensors that you can integrate into your front and rear bumpers for reduced difficulty when parking.  Steelmate has a number of multi-sensor systems that can seamlessly be added.  They feature paintable covers for decreased visibility of the sensors. Just remember that there are two types of drivers out there: those who have been in an accident and those who have not been in an accident YET.

Car Audio Equipment Ideal for Hip-Hop/Rap Music

Ever wonder as to whether or not it makes a difference as to what type of sound system you have in your vehicle that truly fits with the type of music you listen to? Well the truth is that yes, there is quite a significance in sound quality dependent upon pairing up the right equipment to fit into what style of music you prefer to listen to.

Kicker C104 10" Subwoofer

Kicker C104 10" Subwoofer

The best car speakers for Hip Hop music should be designated to make your songs sound great. Hip Hop sounds best on a system that has the ability to create good bass notes and strong midrange sound. The bass notes are vital to make sure the beat is clear through the song. The midrange notes will make the lyrics and backup crisp and powerful.

Earthquake Sound TNT-12S 12" Subwoofer

Earthquake Sound TNT-12S 12" Subwoofer

The best speakers for bass are clearly subwoofers or “subs.” 10 inch or 12 inch subs will hit the bass notes that are too low for standard speakers. When you turn up the bass in a car without subs the music becomes distorted and doesn’t sound right. Add the extra bass of a subwoofer, and it sounds accurate to its production. That’s the extra power of the larger speakers coming in to give the bass an extra hit.

JL Audio TR600-CXi 6" Speakers

For midrange, a good set of 6 inch speakers will fill out the system very nicely. This will combine with the subs giving your favorite songs the quality sound you deserve. 6 by 9 speakers are a little more expensive, but they are even niftier than 6 inch speakers and have a little better range. If you can fit it in your budget, they are a great choice.

Pioneer TS-A6994R 6" x 9" Speakers

Pioneer TS-A6994R 6" x 9" Speakers

With these 2 basic components, you’ll be sure to have a great sounding car stereo. If it’s in your budget you might even consider adding a basic set of tweeters, but they aren’t as important because high notes aren’t as common in Hip Hop as they are in other types of music.

Make sure you check out all of our car audio equipment here at Sonic Electronix, and make sure you find the right system that will truly bring out the definition of your choice in music while you are on the road.

California Legalizes Hands-Free Texting While Driving

In a world where technology gives us the freedom to do whatever we want, whenever we want, it’s not always easy following the rules. One of the more recent laws that we have all had to deal with is the ban on texting and driving. Now I will admit its much more efficient to shoot off a text while out on the open road, rather than pulling all the way over to poke a button or two, but it is in fact 100% illegal to text and drive in the state of California. Luckily a solution will soon be available.

Effective January 1st, Governor Jerry Brown is enacting a bill that will allow you to use a hands-free device that assists you in sending a text message or an email. I know it’s not the most exciting solution in the world, but it’s much better than not texting at all! We’ve all been in the position where you’re trying to shoot off a text and suddenly you look up to find yourself in the next lane over. Not safe! This law will assuredly cut down on your near-death experiences. You’re probably wondering… where can I get one of these fancy hands-free doodads? Sonic Electronix of course, duh.

We actually carry a couple of solutions to texting and driving. First, the Motorolla HZ800 is a Bluetooth ear piece that not only gives you wireless call capabilities, but let’s you dictate your own text messages to send off to your friends. It even cancels out wind noise up to 40mph for a more accurate dictation. Now, if you’re like me and hate things poking you in the ear, go with the Motorola Tz710 Roadster. It’s essentially a Bluetooth speakerphone that clips onto your sun visor, giving you voice commands to many of your phones functions including, yes, texting. This universal piece is great because it’s affordable, and lets you send and receive messages and emails clearly and effectively.

There you have it. No longer should you be a trouble maker, because there are multiple solutions that almost anyone with a Bluetooth phone can do. I’ve got my hands-free device… now it’s your turn!

How to Properly Set Gain on Your Amplifier

Why Set Gain?

NVX JAD8004

NVX JAD8004

People end the lives of their subwoofers everyday and one of the most reoccurring reasons is due to improper gain settings on their amplifiers.  A majority of people mistake gain to be nothing more than a volume knob but that misconception can lead to horrific subwoofer murders.  Knowing exactly what gain is and how to set it will not only prevent your precious power-pushing woofers from meeting their maker, but will also give you the cleanest output possible.  Gain is basically defined as input sensitivity and is used for matching the output from different sources so that they reach optimal performance and minimal damage.  The main thing you are trying to avoid is clipping your signal. Clipping is the distortion that occurs when an amplifier is pushed beyond it’s limits.  At high volumes the music will sound muddy and will cause unpleasant sounds.  If you avoid clipping your signal,  then you will give both your amplifier and woofer a longer lease on life.

Procedure  

With all of that being said, here is a quick way to set your gain:

  • Insert a CD into your headunit that you know to be fairly loud.
  • Play a song and set the volume on your headunit to about 75%.
  • Set the gain all the way down and slowly raise until you experience clipping (audible distortion).
  • Once you reach the clipping point, set it back down so you no longer experience a clipped signal
  • The volume that your headunit was set at during this procedure is now your head unit’s MAX volume.  This is the loudest it will play without clipping and will sound good and clean if you have done it right.

Please note that this is not the most accurate way of doing this but it will get you very close.  If you’re looking to get the most absolutely accurate result then you’re going to want to use an Oscilloscope or Digital mutimeter.  Just make sure you know how to use them!  Another alternative is getting an amplifier such as the JBL GTO-751EZ which features gain LED indicators that will tell you if you signal is being clipped.  For a more in-depth analysis please read our knowledge base article here.

Home and Outdoor Fans

The fan consists of a rotating arrangement of blades which act on the air. The rotating assembly of blades and hub is known as an impeller, a rotor, or a runner. Usually, it is contained within some form of housing or case. This may direct the airflow or increase safety by preventing objects from contacting the fan blades. Most fans are powered by electric motors, but other sources of power may be used, including hydraulic motors and internal combustion engines. Fans produce air flows with high volume and low pressure, as opposed to compressor which produce high pressures at a comparatively low volume. A fan blade will often rotate when exposed to an air stream, and devices that take advantage of this, such as anemometers and  wind turbines, often have designs similar to that of a fan.

Axial Flow Fan

Axial Flow Fan

There are three main types of fans used for moving air, axial, centrifugal (also called radial) and cross flow (also called tangential). The axial-flow fans have blades that force air to move parallel to the shaft about which the blades rotate. Axial fans blow air along the axis of the fan, linearly, hence their name. This type of fan is used in a wide variety of applications, ranging from small cooling fans for electronics to the giant fans used in wind tunnels.

Centrifugal Fan

Centrifugal Fan

The centrifugal fan has a moving component that consists of a central shaft about which a set of blades, or ribs, are positioned. Centrifugal fans blow air at right angles to the intake of the fan, and spin the air outwards to the outlet. The impeller rotates, causing air to enter the fan near the shaft and move perpendicularly from the shaft to the opening in the scroll-shaped fan casing.

Crossflow Fan

Crossflow Fan

The crossflow or tangential fan is usually long in relation to the diameter, so the flow approximately remains two-dimensional away from the ends. The fan uses an impeller with forward curved blades, placed in a housing consisting of a rear wall and vortex wall. Unlike radial machines, the main flow moves transversely across the impeller, passing the blading twice.

 

Make sure definitely check out all the top brands of fans we have available in our new Home and Outdoor section at Sonic Electronix, such as Honeywell, Optimus, and Vornado.
