Subwoofer Basics

You need to run another power wire or you can get a distribution block and split up the wire you already have ran for power. The ground wire you can just connect to a good grounded bolt holding the seats down or something. And as for the RCAs just get a spliter for those too. And on the Kicker subs, The deal with them is that they say that both voice coils MUST be hooked up at all times of it will mess them up A friend of mune had that problem. With the dual 2ohm Kicker’s you can either wire them in 1ohm or 4ohm. You want to wire that accordingly to what you amp can handle. So I went with the dual 4ohm Kicker S15L7 so that I could wire it in 2ohm the dual 4ohm can be wired in either 2 or 8ohm for one channel of my amp. And I will have a 2ohm load going to the other channel.

Integrated amplifier and subwoofer

I do not suggest that you bridge the ParaPix for use with a 4 ohm speaker, but if you plan to try bridging to a 4 ohm load, you are going to need to use a lower voltage, possibly 36VCT transformer, and do the MUTE circuit modification below Bridging The ParaPix amp the easy way: Here’s my bass boost switch mod — Use a 3 pin switch that has two “on” positions on it. Drill a hole in the plate to mount the switch.

Remove the jumper J1 and wire your switch in. The middle pin on the jumper is the constant, and the other two are what you switch between. Info about Transformers for the Parapix amp Well, everyone wanted info about different transformers for the parapix.

January 13, Active Crossover. Funny thing about it, crossovers are easy to understand. What is a Crossover Unit? A crossover unit takes the incoming audio spectrum signal, everything from 20 Hz to 20, Hz and splits it into two or more bands. Those new frequency bands are then sent to different loudspeaker drive units that are created specifically for those frequencies. Think about home stereo units with midrange speakers, tweeters, and subwoofers.

Carrying extra-long cargo that extends beyond the box can adversely affect stability. Powerful gas engine delivers superb starting, idling, and throttle response cc The advanced electronic controls and fuel-injection system deliver superb starting, idling, and throttle response during operation. The engine offers the following performance and reliability features:

The crossover will have built in line drivers which will increase the voltage of the low level signal. This can help lower the noise of the system. Some amplifiers will have an RCA pass through circuit which can be used to drive another amplifier in the system.

Can the repo men hook up your car with you in it? No, it’s illegal to ride in a towed vehicle. However, if you’regetting into the vehicle to prohibit the car from being towed, youcould find yourself in trouble with the law. Once the car is on arepo list, it’s no longer technically yours due to default onpayments. How do you hook up a new car stereo?

Well it helps if you have a repair manual for your car so that you can reference the wiring schematic for the stereo connections it will eliminate a lot of guess work. Using a multimeter find a wire in the connector in the dash that was formerly on the stock radio that has 12 vol…ts when the key is off and this will be your Batt. Now with the key on find a second wire with 12 volts and this will be your Ign.

Bass Cabinet Guide

There are settings on your surround receiver and there are settings on your sub. Getting the correct subwoofer settings for home theater means correctly configuring and understanding both. This guide will take you step by step in doing just that. Setting up your subwoofer properly will almost always affect your entire system and is well worth it for those looking to achieve the best possible movie-watching or music-listening experience.

The frequency below which your subwoofer will be working and the frequency above which your main speakers will be reproducing frequencies for anything sent to the LFE or sub channel.

The LC2i, is a compact, two-channel processor with active input circuitry, which allows it to accept speaker-level signals of up to watts per channel from factory-installed source units or amplifiers.

How to Install a Car Amp Installing car audio amplifiers is one of the trickiest things a newbie car audio installer can attempt. Car amp installation requires that all sorts of panels be removed and that various wires be run all over the car. Installing car audio amplifiers is a step by step process which I have outlined here. If you have any questions please contact me by clicking here. Please do not attempt a car amp installation if you are not comfortable with the process.

Leave it to a professional. Now here are the steps on how to install a car amp. There is also a wiring diagram below.

Subwoofer hookup question

By Andrew Pouska The bass cabinet is the box with the speaker. The materials used to make a bass cabinet do not seem that impressive. But, there is a lot that goes into designing the cabinet ensuring everything works together and creates a good reproduction of your bass tone.

2. Connect the audio signal from the stereo unit to the audio inputs of the active crossover. Connect the outputs for each crossover band to the appropriate amplifier, i.e. route the low signal to the subwoofer amps, the high signal to the tweeters, etc.

To order call Subwoofers are often misunderstood, both in name and in application. While they have a reputation for providing hefty bass lift, they need not be proverbial bulls in the china shop of your listening room. First, the basic definition: A subwoofer is a loudspeaker that produces low frequencies that augment and extend the bass output of a full-range loudspeaker system.

The term subwoofer is grossly misused to describe any low-frequency driver system enclosed in a separate cabinet. A low-frequency driver in an enclosure with an output extending to 40Hz and used with small satellite speakers is more properly called a woofer. Most of these products actually employ woofers that are simply driven by an integral power amplifier.

Such a design relieves your main amplifier of the burden of driving the woofer, but the speakers must be plugged into an AC outlet. Read on to find out about different types of subwoofers—and their pros and cons—as well as their setup, placement, and integration. Passive Subwoofers Subwoofers come in two varieties: A passive subwoofer is just a woofer or woofers in an enclosure that must be driven by an external amplifier. In one variation of the passive subwoofer, the same stereo amplifier driving the main speakers also powers the subwoofer.

In this least desirable method of connecting a subwoofer, the full-range output from a power amp is input to the subwoofer, and a crossover in the subwoofer removes low frequencies from the signal and outputs the filtered signal to the main loudspeakers.

Buffered input and output stages Individually variable outputs trimpots On-board RCA connectors Made from standard components In the higher performance speakers, the crossover networks are often very complex and they can be very difficult to design and optimise. And because they usually do attenuate the midrange and high signals, that means they do waste amplifier power.

They also interpose a complex network between the speakers and the amplifier which means a loss of damping factor, particularly for the lower frequencies where it is most needed, if you are to achieve tight, clean bass and midrange reproduction. It replaces the crossover currently in the speaker enclosure. OK, so that’s the passive approach. It involves just one stereo amplifier to drive the two speaker boxes in a stereo system.

By switching the amp to mono-bridged operation the polarity of one of the amp channels is reversed. Reverse the polarity of that speaker connection and the two speakers are working in phase, but one channel of the amp is backwards.

I am back again because I had to purchase one more K8. I have fallen in love with this little giant.. If that’s the main reason listen to this.. Get the specifications sheet for the speaker and load them using the PA2 app. Trust your ears and tune your speakers from the front of house.. Your sound will forever deliver all the quality and punch you will ever need..

If you eliminate the distortion and keep your meters in the green your system will deliver sound you never knew you had.. I am totally blown away with the amount of clean green signal volume I am able to produce.. I am always surprised every time I hookup my set for an event and hear that clean rich sound produced by these speakers tuned Sweetwater is a great company with outstanding customer service.. Go Mike W by Wyatt R. Powerful and great clarity. Bass response is very good. I’m using them for my keyboards.

The Crossover Basics and Resource Guide

Installing Multiple Amplifiers There seems to be some confusion when it comes to installing more than one amplifier. Should you use one power wire or multiple wires? Do you ground everything to the same point? How do you split the low level signal? Let me share my thoughts on the topic of installing multiple amplifiers.

In an earlier article we looked at the issues involved in connecting multiple speakers to one amplifier. In this article we look at some of the practical ways of wiring four speakers to each amplifier (left and right). For example, it is normal to have your main HiFi amplifier in the lounge room.

Carrying extra-long cargo that extends beyond the box can adversely affect stability. Dual A-arm front and rear suspension provides a smooth ride over challenging terrain and excellent hauling characteristics XUV front suspension detail To complement the most capable frame available in a high-performance utility vehicle, the XUV is equipped with four-wheel independent suspension.

The entire suspension system has been optimized to handle no cargo to maximum cargo without compromising ride quality or vehicle stability. Dual A-arm front suspension features include: Unequal length, dual A-arm construction for superior wheel control and travel Power is transmitted from the engine through a continuously variable clutch system to the transaxle. Key elements of the drive system include:

Adding subwoofers to your PA system

Bridging Power Amplifiers Biamplification vs. Bridging Power Amplifiers – page 2 Conservatively, let’s only add 1 dB for the improvement in woofer output due to elimination of the woofer series inductor in the passive crossover. The tweeter is capable of an average output from dB in excess of the woofer, and the phenomenon of masking will allow the tweeter to cover up the woofer clipping by at least half of that, or dB of additional output before the output becomes noticeably distorted.

Again, that is a conservative number. That’s at least another 4 dB total increase on top of the nominal text book 6 dB for biamplification, or a total increased SPL over the single channel use of 10 dB.

All wiring to and from the crossover should avoid all moving parts in the vehicle which could potentially damage the wiring. Take great care when running wires through the door frame and into the door as wires can easily be cut.

Discussed here are some tips that describe the most popular method of wiring Speakers. There are several ways to wire up Speakers, the most common methods are Series and Parallel which are discussed here. Wiring up Speakers correctly to provide the best possible sound, requires some knowledge of Loading, Phase, and Impedance, while understanding Ohms Law will help you to connect your speakers properly.

Adding Speakers in series increases the overall resistance of the circuit. Therefore the resistance of each Speaker is added together, For advanced installations with Multiple Speakers, Series Speaker wiring can be used to increase the resistance of the “equivalent” or “overall” resistance that the Amplifier sees. This allows the Amplifier to run cooler and more efficiently. Series Circuits are “voltage dividers”, and using Ohms Law, one sees the result as a decrease in amplified voltage audio signal to each Speaker.

Since Series Circuits are “voltage dividers” each Speaker sees a percentage of the amplified output from the Amplifier. It is often assumed the Amplifier is producing less output, but it still produces the same output, because each Speaker only gets a percentage of the overall power. However, increasing the resistance to more than 4 ohms of speaker resistance by adding Speakers in Series, will split the amplified audio output from the Amplifier across all the Speakers in the circuit.
