Personal Review: Kicker ZX750.1 & Earthquake Subzero

Being an employee at Sonic Electronix,  it’s nearly impossible to avoid buying car audio equipment.  I for one could not resist the temptation.  I indulged in the Kicker ZX750.1 amplifier paired with the Earthquake Subzero SZ-10 subwoofer.  Im here to give you my honest opinion and review of my choice and maybe help you along the way in making a choice of your own!

Kicker ZX750.1 

Kicker ZX750.1

Kicker ZX750.1

First off lets start with the amplifier.  The ZX750.1 is the perfect match for my subzero.  This amplifier pumps out 750W RMS at a 2 ohm load, perfect for the Dual 4 ohm sub which wires to a final impedance of 2 ohms.  However, the birth sheet states over 900 watts RMS which my sub can scarf down with ease.  The amplifier’s chassis is compact enough to allow me to mount it on the sidewall of my small trunk, space is at a premium.  Tuning the amplifier was a breeze because it includes a low-pass crossover frequency selector, bass boost and gain adjustment.  While some people might find the simplistic design of a monoblock amplifier to be a bad thing, it made it easy for me to find the desired sound I was looking for right away.  I turned the gain 1/4 a turn to match the 2 volt output of my headunit so the signal won’t clip, meaning my bass will sound crystal clear with no pops, thumps or crackles even at high volume.  The amplifier dissipates heat very well, even after extended periods of brutal bass notes it was only warm to the touch. I can play sweet bassy songs all day long without this amplifier breaking a sweat which is good news when it comes to my addiction to bass.  I tried to come up with shortcomings for this amplifier but so far I’ve had no negative experiences.  It’s priced reasonably for the build quality and power output and has been quite reliable for the duration of ownership.  If anyone tries to tell you that Kicker amplifiers are garbage, don’t listen to them….just don’t.

Now the fun part!  If you are unfamiliar with Earthquake Sound, you are probably not alone.  They are a brand that should be as well known as Kicker or JL because of their high quality system components.  The Subzero is one of their top of the line subwoofers and I decided to go with one of their 10″ versions.  You might be thinking that just one 10″ subwoofer will not produce the pounding bass that two average woofers could produce but you would be wrong my friend.  I have this in a 1.0 cubic foot sealed box which is not exactly ideal for maximizing bass output in comparison to a vented enclosure, but that is exactly what it does.  This sub is rated at 750W RMS and like I stated previously, im pushing over 900 watts to it so it pounds hard and loud.  Connecting this subwoofer to the amplifier was easy due to the PSP terminals on the Subzero which use fuses to give you different ohm loads.  This eliminates the use of pesky jumper cables between the terminals.  The only complaint that I have is that my car is falling apart from all of the bass rattling the screws right from their panels.  I need to sound dampen my car to reduce vibrations and rattling before it’s too late.  If you’re wondering, it does play every genre of music exceptionally well, from the low bass notes of E-40 to the soothing bass lines of Sublime.

Oh, did I mention that it has some serious excursion? If you don’t believe me, check out this video of my Subzero and amplifier in action.  Enjoy : )

Marine Vs Car Audio

Marine AudioEnjoy The Water

2012 offers an abundance of new audio equipment for your aquatic satisfaction.  It’s not quite summer, but now is the perfect time to start thinking of upgrading your watercraft’s audio components!  Marine audio can be installed on the likes of boats, sea-doos, jet skis, motorcycles, ATV’s, ect.  As opposed to car audio, marine audio is usually more durable and weather proof to allow for excessive wear and tear.  Getting the gear you need now will ensure an audio-inducing summer.

                                              The Difference

Kicker 10ZXM7005

5-Channel ZXM Series Marine Amplifier

Marine audio differentiates from car audio in a few major ways. Marine amplifiers and subwoofers are water resistant due to their increased exposure to salt or fresh water. They have special manufacturing designs such as watertight seals, coated circuit boards, and waterproof wired remote controllers. Another thing to take into consideration is sunlight exposure.  Usually, audio components are going to be exposed to long hours in the summer sun.  To compensate for this, manufacturers will coat parts with ultraviolet resistant materials.

10" Single 4 ohms Marine Subwoofer Driver

When your audio components are wet or dampened, they are susceptible to corrosion.  Marine speaker wire is designed to reduce the risk of corrosion with stranded copper wire.  This wire also makes it flexible which is great for absorbing shock damage caused by the movement of the harsh marine environment. Due to the openness of a marine environment, marine speakers will always have hard dome tweeters to create the loudest sound projection obtainable. Marine head units will have rubberized buttons and splash guards to protect the internal parts from being wet. Today, there are an abundance of manufacturers who offer multiple lines of marine audio products to fit your specific needs.

What Car Amplifier Do I Need for My JL Audio W3v3 Subwoofer?

In this week’s What Amplifier Do I Need? we will be looking at JL Audio’s W3v3 Series Subwoofers. The W3v3 subwoofers are available in a 6.5”, 8”, 10”, 12”, and 13.5” size option that will satisfy any personal preference. The woofers range from 150W RMS to 600W RMS depending on the size of the woofer. JL Audio is known for manufacturing amazing drivers that are able to produce unsurpassed bass reproduction but even these amplifiers can’t power themselves up, they need the right amplifier to perform.

JL Audio XD200/2


If you are going to go with a JL Audio subwoofer might as well go with a JL Audio amplifier. The JL Audio XD200/2 is the perfect amplifier when wanting to get your feet a little wet. This amplifier works perfectly when wanting to amplify a single 6W3v3-8 or a single 8W3v3-4 subwoofer when bridging the 2-channels. The amplifier will put out 150W RMS at 8 ohms bridged or 200W RMS at 4 ohms bridged. There really is nothing better than a JL Audio amp, this amp will be extremely efficient and features technologies like Advanced Thermal Rollback in order to eliminated thermal shut-down events. The amp features low and high pass filters as well as noise killing differential-balanced inputs for clean and reliable power output.

Alpine MRX-M50


The Alpine MRX-M50 is rated at 500W RMS @ 2 ohms, making it the perfect amplifier when wanting to run a 10W3v3-2, 12W3v3-2, or a 13W3v3-2 subwoofer. Its small design and both high-level and low-level inputs allow this amp to be installed in virtually any vehicle, not many other amplifiers can offer that. The amplifier also features a variable bass boost along with a low-pass filer and subsonic filter that will allow you to manipulate the frequencies to your personal taste. When purchasing an efficient sub like the W3v3 you need an amplifier that is just as reliable and also affordable.

Boston Acoustics GTA-100m


Boston Acoustic’s GTA-1000m monoblock amplifier is rated at 600W RMS @ 4 ohms. This amp will allow you to run a 10W3v3-4, 12W3v3-4, or 13W3v3-4 subwoofer to a final super efficient impedance of 4 ohms. This is going to give you the best performance, the amplifier won’t have to work as hard and draw less power for lower thermal output. The woofer will run more efficiently as well due to the constant supply of undisturbed power. The GTA-1000m features balanced asymmetrical inputs for noise cancellation and fully adjustable and selectable low and high-pass crossovers for complete customization of sound reproduction.


Battle of the Subwoofers: JL Audio W3 vs Alpine Type-R

Last week we discussed the differences between a Rockford Fosgate P3 subwoofer and a Kicker Solo-Baric L7, and focused on the features that set them apart from each other. In this week’s second “battle” we will go pound for pound with the Alpine Type R and the JL Audio W3. Both of these series of car subwoofers are considered high quality and never disappoint.

JL Audio 12W3v3-2


JL Audio is one of those companies that everyone knows by name. Even if they have never heard any of their drivers people will still tell you that JL Audio is considered one of the top companies in the car audio industry. Hard work and precision goes into all of their products and nothing could be more true about JL Audio’s 12W3v3-2 W3 series subwoofer. Many of the subwoofer’s patented technologies focus on the response and linear movement of the subwoofer, making it one of the most accurately precise woofers on the market today. While the W3 will sound great in a ported enclosure it was design to perform at is best in a smaller sealed enclosure, allowing the subwoofer to produce tight, crisp, and clean bass every single time. One of the coolest things about the W3 is that while other woofers suffer under lower power conditions, the W3 does not; in fact it will still reproduce clear and tight bass at multiple power ranges. The W3 is really the subwoofer that was designed for those who don’t want to miss a beat.

Alpine SWR-1243D


Alpine’s SWR-1243D Type-R series subwoofer is one of the most top rated subwoofers not only on our site but within the car audio world and for a number of very good reasons. With an RMS power handling of 600 watts, this woofer is able to really reproduce some hard hitting bass. Alpine’s patented High Amplitude Multi-Roll surround allows the woofer do deliver deep and clean bass. The Type-R woofer is known as a power hungry subwoofer meaning that it wants all the power it can handle because it was designed to play loud. One of these woofers is more than enough to make your car shake eliminating the need for additional woofers, unless of course you want more power and want the entire block to hear you coming. This woofer is able to combine SPL with SQ and a price that is more than great. Its ability to be a versatile subwoofer, really sets it apart from other woofers who are more proned to play better under one condition than the other.
