Installing amp and sub diagram

This step will be the same regardless of whether you are wiring in series or parallel. My amp is a mono block amp but has 2 positive and 2 negative terminals. Then place the negative of the second voice coil to the negative contact of the same channel of the amp.

I have a watt sub dvc 2 and a watt amp. Soundstream reference ref4. And i've switched out all rca cables.

To wire an amp, you'll need to connect it to your vehicle's battery. If the subwoofer features spring clips in order to use speaker wire, then you can use the speaker output of the receiver to hook it all up. Also has slave input don't know to much besides gotta be precise when wiring the subs and tuning the amp. You can then plug the cord. So i need help with connecting my 2 subs a my amp. And negative on one amp and positive on other amp.

If you have a 2 ohm stable amp, and two 4 ohm subs then you should wire them in parallel. Connect the amp to the first speaker. If the subwoofers are wired to a total impedance of 4. Then do the same for the second sub. Also i've hooked up an old amp that i knew worked and still had no sound to subs. They are new subs and have been hooked directly to the head unit and work.

Then place the positive of the first contact to the positive of one channel of the amp. You can, those should be dual voice coil subs, if you are using 2ohm dual voice coil and wire them in series the amp will see 2ohms ideal watts rms to each sub if you wire them in parallel the amp will see 0. Feed the power cord through the vehicle, hiding it in the plastic panels along the floor, until it reaches the trunk.

From the wires coming out of the speaker, connect the positive speaker lead to terminal a the positive for channel 1 and connect the negative speaker lead to terminal d the negative for channel 2.

Our subwoofer wiring calculator allows you to figure out how to wire your dual 1 ohm, dual 2 ohm, and dual 4 ohm subwoofers in several different qualities. Estimated wait for next available agent :. All of our representatives are currently chatting with other customers. For Tech Support, call I belong to a culture of fine sights and sounds, and I like spreading the word.

I've been tinkering with electronics ever since I was a kid - starting with taking apart and putting back together televisions and radios. I always got them back together again and working. I took courses in radio and electronics as a teenager, and became a ham radio operator.

I worked in my high school's stage crew, running sound, lights, and a movie projector. After college, I joined a rock 'n roll band as the soundman and learned how to lug around and operate the gear that helps make music sound good and loud.

Working in a music store in Austin, Texas, I spent a few years manufacturing, installing, repairing, and operating sound systems. Our customers were recording studios, nightclubs, and touring bands.

Eventually I moved back to Charlottesville, Virginia and opened a small demo recording studio. In , I finally came to my senses and got this job at Crutchfield. They actually pay me to ramble on, rant, and explain the things I love about music, electronics, and getting good sound.

Given my background, they put me to work writing about some of the most complex electronic products Crutchfield sells: car amplifiers, digital signal processors, wiring, professional sound mixers, and PA systems. There are many ways to wire subwoofers and amplifiers together. The ideal setup is when subs and amps match their impedance and power capabilities to optimize performance.

In this article, we'll help you find the best subwoofer wiring diagram for hooking up your system. Just click on the "AMP" or "SUB" box below, answer a few questions, and you'll be presented with the wiring diagrams relevant to your search. You can find a glossary of terms below the interactive module. A Single Voice Coil subwoofer or svc sub has two wiring terminal posts, one marked positive and the other marked negative. A Dual Voice Coil subwoofer or dvc sub has four wiring terminal posts, two positve terminals and two negative terminals.

The extra terminals give you more options for wiring the speaker. The impedance of a subwoofer coil is expressed in ohms. Impedance is the amount of electrical resistance, or load, a sub puts up against an amplifier's output. Subwoofer voice coils usually come in 2-ohm, 4-ohm, or 8-ohm impedances.

The value is often found printed on the magnet, if you're unsure of what you have. These terms refer to two ways of routing the speaker wires to your subs to properly manage the overall impedance load. Whether you need to use a series wiring configuration, parallel wiring, or a mix of both, our diagrams will show you exactly the best way to wire your speakers. Note: When you wire dual voice coils and multiple subs together, the resulting total impedance is not always simple to figure out or practical to use.

An amplifier will put out more power through a low-impedance sub than it will through a high-impedance sub. But a lower impedance also means more stress on the amp.

Some amplifiers can even drive a 1-ohm load safely, and achieve maximum output. Refer to your amp manufacturer or owner's manual to determine whether or not yours can handle a low-impedance load. Bridging an amp combines two amplifier channels into one, to get more power. The disadvantage of bridging is that bridged channels can't drive impedance loads as low as they can when unbridged.

How to bridge the amp is usually indicated at the amp's speaker wire terminals. All the wires depicted in the Subwoofer Wiring Diagrams are speaker wires. For wiring subwoofers, we recommend using wires of to gauge in size. Now that you've seen how to wire subwoofers and amplifiers together, you can knowledgeably shop Crutchfield's extensive selection of subwoofers and amplifiers.

If you want to learn more about amplifier systems, check out our Amplifier Installation Guide. Hello, Buck Pomerantz and others at Cruthcfield! I don't have any bass coming from the subwoofers and really don't even hear them.

I looked to see how the installer wire the speaker inside the sub-box, and he wired both positive wires together and ran them out to the sub by means of a connecting wire, and wired the two negative sub wires together and ran them to the sub by means of a connecting wire.

To get more volume from the subs, how should I rewire them? I'm thinking using one positive and one negative from each sub to its respective channel, and just covering the bare end of the other two wires so they don't "accidentally" touch anything on the sub. Infinity reference x2 with infinity kappa six, I want to use the 2 ohm for watts, but I am getting confused with the monoblock 2chanel out, How do I wire this for 2ohm load?

With a 2 channel 1 ohm stable amp and 2 single coil 4 ohm subs, does the parallel wiring for the second sub have to come directly from the 1st subs terminals? Couldn't you just take both speaker leads to one positive and one negative on the amp? I can't find a dual and single coil wired together. I plan on purchasing the Rockford Fosgate RX1 to power these subs in a ported box within the specs for these subs. My question is what will be the best way to wire these subs and get the most out of the amp?

I am a bit confused as to this amp being a mono block amp but has the connections as a 2ch amp would. Pls excuse my lack of knowledge as I am learning from past mistakes on junk gear! Money is a little tight and this amp seems to fit the budget.

I have a 4ch rockford amp that is powering my door speakers, so this will be a second amp for the subs alone. Do I need a bigger amp for these subs? I have read that they can be wired to 1ohm, but i'm no expert.

Any advice is helpful. Thanks in advance. I have Ford ranger ext cab. I have a speaker box with two 12 inch fosgate R2's and watt amp. The box is made to fit truck and a friend tells me my speakers should be facing the floor. The speaker box seems to fit that way but my bass isn't carrying.

Should my speakers be facing another direction? Wanting to just run sub power connection using amp. I'm having issues where the amp is going in to protect mode to early. Like I just burn it up a little get going and then it will just intermittently cut out. I'm wondering if this is because I have it wired incorrectly?

How should I wire these subs to be proper? Our subwoofer shopping guide will help you determine which kind of subwoofer and bass system you need, to get the sound you want. Here we discuss the most popular fixes for an underpowered electrical system: the big 3 upgrade, a capacitor, a high output alternator, and a second battery. What does the gain control do anyway? This article describes how to adjust your amplifier so that your subwoofer sounds just the way you want it to.

A pictorial diagram would con more detail of the subconscious appearance, whereas a wiring diagram uses a more figurative notation to heighten interconnections beyond inborn appearance. A wiring diagram is often used to troubleshoot problems and to create sure that all the contacts have been made and that anything is present. Architectural wiring diagrams work the approximate locations and interconnections of receptacles, lighting, and enduring electrical services in a building.

Interconnecting wire routes may be shown approximately, where particular receptacles or fixtures must be upon a common circuit.
