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

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 : )

Earthquake Sound’s Best Valued Subwoofers

For those of you who aren’t interested in spending a lot of money but would love to get some bass in your car, there is an answer. Sonic Electronix is proud to offer both the DB Series and the TNT Series subwoofers by Earthquake Sound. These subs are similar in price but very different in design, and we are going to highlight some key features of each series.

The TNT Series Subwoofers feature an extremely high cone excursion for maximum movement of air. The high-roll foam surround allows the speaker cone to maintain complete linear movement while moving rapidly, which assists the cone in achieving its excursion. This series is designed for anyone interested in getting an explosive sound at the most affordable price possible. The voice coils on these subs can withstand high temperatures, allowing the magnet motor structure to operate cleaner and more efficiently. Earthquake Sound has stripped the subwoofer down to its basics with the TNT series, allowing more focus on the performance and not the flashiness.

The DB Series Subwoofers are similarly priced to the TNT’s, and they offer a higher quality output that matches perfectly to any high end set of car speakers. You’ll be impressed with the DB subwoofers once you hear them. They produce hard hitting bass with smooth transient peaks. The Pulp Fiber subwoofer cone sounds excellent in lower frequencies, and produces a very smooth and transparent roll-off into higher frequencies. Backed by a 5-year manufacturer warranty, it’s easy to see that Earthquake stands behind their products. If your sound system is lacking a lower sound stage, the DB series subwoofers will fill that gap.

When it comes down to the decision, you will be happy no matter which of these car subwoofers you decide on. The TNT’s will put some bump in your trunk; while the DB’s will seamlessly fill that lower music range with quality, hard-hitting bass. Earthquake Sound has it all, so look no further.

Not only will the subwoofer be aesthetically pleasing but it will sound amazingly precise and deliver bass like you have never heard or felt before. This is exactly what will happen when you set your eyes on the 2004 CES Innovations Award winning Earthquake Sound Subzero series subwoofer. This series of subwoofers are available in a 10”, 12”, and 15” model, ranging from 750 watts to 1250 watts of RMS power handling. Just because they all look the same does not mean they all sound or are built the same. Each woofer is uniquely design and built to accommodate its respective size. The Subzero series subwoofers feature many technologies that put them a notch above the rest and give them the label of high-end subwoofer. Subzero subwoofers are set to re-define what a high-end subwoofer should look and sound like. These subwoofers will offer quality, performance, ease of use and superb constructional design that will not be easily matched by other subwoofers within the car audio industry.

The materials allow the subwoofer to reproduce clean, efficient, and powerful bass while also giving the woofer a sense of longevity and reliability. The SZ-12 car subwoofer is also equipped with a nomax/romax spider assembly meant to assist with accurate reproduction by maintaining the single piece piston as linear as possible. The high strength and power magnet motor structure moves the 3” over-sized, flat-wire voice coil that offer more surface area which increases the overall motor strength and sound reproduction. With a subwoofer of this magnitude it is important that it remain cool, the use of Turbine Cooled Transducer (TCT) technology keeps the woofer cool and running efficiently during long or short listening sessions, making sure the woofer is giving its best at all times.
