Want to hook up your own subwoofer?

Lately I’ve been doing a lot of research on car audio (being that I am one of the newest team members here at Sonic Electronix) and even though I highly recommend you get this done by a trained professional, there is always an opportunity to learn something new and try it yourself. Stereo systems are at least as simple as most other single accessory electrical systems, but they are still electrical systems. Physically wiring the system is the easiest part of installation. The rest of it is knowing what you’re working with and figuring out what to connect to what and in what way. But once you know what all those numbers and ratings on the amps and speakers mean, the process pretty much explains itself.

First and foremost you need to determine your amplifier’s minimum stable impedance  in ohms of resistance. You’ll typically find the stable impedance rating between 1 ohm for a powerful amp and 5 to 10 ohms for a less powerful one. The lower the amp’s stable ohm rating, the more power it can transmit through a single channel without frying. For this blog, I’m going to explain this if I were using an amplifier with a 2-ohm minimum staple impedance.

Now go ahead and check your subwoofer’s ohms of impedance. This works the same way as the amp does; a massive, powerful subwoofer has large coil windings that provide little resistance to power flow and a smaller speaker provides more resistance. This will determine whether you need to wire the subs in parallel or in series. Compare your amplifier’s ohm rating to the speakers. If the speaker ohm reading is lower than the amp’s, then connecting that single speaker directly to the amp output will fry your amp. You’ll need another speaker and you’ll need to connect the speakers in a series circuit instead of a parallel circuit.

Connect a parallel circuit in just the way you’d think ( positive to positive and negative to negative). As long as none of the speakers in your system have a lower ohm rating than the amp, then you’ll want to connect them directly to the amp terminals. This will give you the best chance at nailing down the ground pounding power you are looking for.

Connect the first part a series circuit by wiring the positive lead of one speaker to the positive terminal on your amp. Connect the negative terminal on that speaker to the positive terminal on the next in your series. If you only need two speakers to meet your amp’s minimum impedance, then connect the negative terminal on the second speaker to the negative terminal on your amp.

Wire as many speakers into the series as you need to meet your amp’s minimum amp impedance. Connect them all positive to negative with the positive and negative terminals on the speakers on the ends of your series connected to the appropriate terminals on your amp.

Now do remember that every car is different, so if you have any questions feel free to contact us here and Sonic Electronix and we’d love to help you out. Of course it’s going to be a little intimidating, but please make sure that you never work on your cars electrical system unless you are absolutely comfortable with it.

Lanzar OptiDrive Series Amplifiers

LanzarUnleash the Beast

If we know our customers, bass is one of the most important aspects of their audio systems.  In order to achieve such bass, you must have an amplifier that will be able to fill the bill. The folks at Lanzar have revamped their OptiDrive series amplifiers for 2012.  Most of these beastly amps are now 0.5 ohm stable meaning they are ideal for competitions and daily use alike. Having the ability to maintain 0.5 ohm stability can keep the frustration away from people who own Dual 2 ohm subwoofers.  Two Dual 2 ohm subwoofers can ether be wired in Series configuration at an impedance of 2 ohms or in parallel configuration at an impedance of 0.5 ohms in which these amplifiers can accomplish.  The OptiDrive Series is available in ten monoblocks and two 4-channel models so you can be certain that you can find an amplifier to fit your application.

An amplifier is only as good as the versatility and quality it can achieve.  The Optidrive Series amplifiers all share a variety of different functions and features that make them an invaluable purchase.  They all include built in low and high-pass filters for proper tuning and sound customization. The included wired bass control knob ensures that bass levels can be conveniently controlled from a user-defined location. Pre-amp outputs are present to daisy chain multiple amplifiers together which is ideal for competitions.  As well as a heavy duty power coated heatsink for maximum heat dissipation.  Combined with a subsonic filter and a 180 degree phase control, you have an amplifier that is ready to take on any challenge.

Making Matching Easier

One of the most common questions asked at Sonic Electronix is, “How do I know which amplifier I need for my subwoofer?”  This can be a hard or even intimidating question for some but fear not Sonic Electronix has your back!  Introducing our brand new AmpliFinder tool.  AmpliFinder is an amplifier finder tool that will take away the confusion of pairing a subwoofer with an amplifier.  Not only will it tell you which amplifier you require, but it will give you a complete list of every amplifier that is suitable for your subwoofer.

JL Audio W7 Subwoofer

MTX RT500D Amplifier

How it Works

AmpliFinder will lay out the possible wiring configurations for your subwoofer.  Depending on the ohms and number of voice coils of the subwoofer, different wiring configurations will be displayed.  AmpliFinder will also take into account the RMS power rating of each subwoofer to appropriately match that of the amplifier.   Just select the manufacturer, model number, and the number of subs you wish to power and prepare to be wowed by the abundance of possibilities.  For example,  the Earthquake Subzero SZ-10, when input into the AmpliFinder will give you the Kicker ZX750.1 as a choice which is a perfect match for the 750 watts RMS subwoofer.   Also, the JL Audio 8W7AE-3  when entered will give you the MTX RT500D which is a perfect match at 2 ohms as well.

Kicker CompVR Subwoofers


By Chelsey P. – Sonic Electronix Writer

As you may already know, the Kicker brand features exceptional products, especially when it comes to their subwoofer line. They consistently design subwoofers that out-perform the competition. Today we are going to discuss two Kicker subwoofers that have different styles and power ratings, yet both stand out in today’s line of car audio subwoofers.

The Kicker CompVR subwoofer line delivers high-performance sound with superior bass and durability. The Kicker 07CVR124 12” Dual 4 ohm subwoofer is part of the CompVR line. The power handling is simply amazing since it pushes 400 watts RMS. The CompVR’s are made with a polymineral injection molded cone that remains rigid and lowers distortion. This unique cone eliminates flex by using a 360-degree back bracing and aluminized coating.  The top-plate design, dual voice coils and motor structure allow the sub to handle intense power without breaking down.

Looking for something with less power, but still has that great Kicker name.  The Comp Series is perfect for someone who wants just enough quality and bass without breaking the bank. The C104 is a 10” Single 4 ohm subwoofer capable of pushing 150 watts RMS. The vacuum formed polymineral cone and ribbed surround are stitched together for durability and strength. This woofer will provide good solid bass that is going to last you a long time.

As you can see, Kicker subwoofers will work great for any application. They represent the best balance between high-value and high-performance in today’s market.
