You have one of the new style microprocessor controlled battery chargers. This is fully automatic. A light will come on telling you when the battery is fully charged. When the battery is fully charged this battery charger automatically shifts into a float charge mode. This battery charger will not over charge your battery. It will take several hours to fully charge an automotive battery at 2 amps. I hope you used distilled water in the battery. Tap water contains trace amounts of minerals and chemicals that can shorten the battery life.

Understanding Caravan and Tow Car Electrics

Let me say right up front that you only need to read this article if you are lucky enough that your group is getting bookings in large or outdoor venues. But if you have a good set of main PA speakers that are starting to sound strained at those large gigs, you might want to think about a next logical step. You can send comments, questions, or scathing diatribes to Larry at lmundy attbi.

As I said at the end of that article, the result worked great. This requires PA speakers and amps that can reproduce a full spectrum of sound. For most folks with a decent PA setup, this means simply adding subwoofers and subwoofer amps to extend the low range of the overall system.

The price difference between two wire gauges (i.e. 4 gauge versus 2 gauge) is negligible compared to the cost of having to run a second or larger wire in the future. I would run one wire for several other reasons as well. First, it’s usually cheaper than two wires in terms of material and labor costs.

Battery Wire Size and High Output Alternators When upgrading to a higher output alternator you should always install a larger wire between the alternator and battery. Even with a standard output alternator you will get better performance and life out of your alternator if you upgrade the main battery wiring. The original wire just isn’t large enough for proper power transfer.

If you are using your alternator to it’s maximum output or when you upgrade to a higher output Alternator you must increase the wires size. An alternators ability to send the power it is making to the battery is directly related to the wire size and quality of connection between the alternator and battery. Also, a wire that is to small when used on a high output alternator can cause the power to back up within the alternator making it overheat, burn up and fail.

Another area that little is paid attention to is the ground. You must also improve the ground as well. A poor ground will hinder the alternators ability to send power to the battery and can burn an alternator up just as fast as an inadequate alternator to battery wire. Your ground may be fine when you first install your alternator but over time corrosion and resistance builds up in the ground connections. This is why it is best to run the ground directly from the rear of the alternator to the battery.

The car amplifier doesn’t provide a signal to the sub

Saturday, March 27, – I mean if you bridge them, you can only use one amp as the main unit that goes to your speakers or subs. Bridging is something I am not very familiar with, but I believe other people might be of some help.

Sep 30,  · Though, you can get a cheaper one. You don’t need to fuse them. Atleast, I don’t. I used to run 3 amps in my car. As for the remote wire, since you .

This diagnostic will help you find the most common causes of starting problems for the TSX. It can be frustrating trying to figure out why a car won’t start; you have places to be, and your long reliable Acura has finally let you down. But if you can pinpoint the symptoms, you can figure out the problem. Does your engine not crank at all? Then start with the battery in Step 1.

Do you hear a clicking sound when you try to start the car? If so, then look at the starter in Step 4. Regardless of your starting problem, we can figure it out. Materials Needed Battery charger Step 1 — Is the battery charged? If your engine doesn’t crank, then it’s most likely because your battery doesn’t have the charge required to power the starter.

Decide how much, and what gauge power cable you will need. Decide how long your RCA cables will need to be. You should take into account that the cable will be running from the center of the car, out to the side, and around several bends and curves. When deciding how much power cable, think about how you will run the cables first!

Oct 12,  · Connect the amp’s negative terminal to the car’s chassis ground. Use a short negative power wire that is the same diameter as the positive wire that leads to the battery%(58).

How Do I Hook Up my subwoofer? Hook up Powered Subwoofers: Receiver Pre-Outs Before trying to hook up your subwoofer, you need to identify the connections it has. First, take a look at the back of your subwoofer. There may be more, but this is all you’ll need to properly connect your subwoofer. The last piece of prep work is for you to check your receiver. If you don’t have this output, you won’t be able to connect your sub this way.

Refer to Connecting a Non-Powered Subwoofer to get your subwoofer connected.

FAQ, Frequently Asked Questions

You got right down to my core misunderstanding. My epiphany occurred on the idea that “the entire chassis is an extension of the minus terminal of the battery”. I’m still wondering why cars are designed this way, but that wasn’t in my original question. To be shocked, you have to touch two points that are connected to opposite terminals of the battery. And the voltage is low, yes. I had a car once where the chassis was painted–I had to scratch the paint if I wanted to make electrical contact.

You can wire two amplifiers, or even multiple amps, in one car audio system, but it takes some extra planning. The main factors that you need to consider when you wire in two or more amps are how you will deal with the power cable, grounding each amp, and whether or not the remote turn-on signal from your head unit is strong enough to split between multiple amps.

Low RPM turn on and charge Fits factory applications Low and high current applications Multiple finishes available But now that people are driving their classic cars more often, and upgrading them to be more drivable, they are also adding more electrical components so that driving them is more enjoyable. Some cars also have an air suspension system, meaning the compressor needs to keep that air tank full — and that draws on the electrical system more than ever was intended.

Upgrades to digital ignition boxes and alarm systems also add to the amount of wiring that is added to a vehicle; people are also adding electric cooling fans to replace the mechanical fan. So how do you upgrade an electrical system that was never designed for all of these accessories? Many factory alternators from the classic car era had gauge wires, which are not sufficient to handle higher alternator outputs.

One solution to the charging dilemma is to upgrade to a single-wire alternator that puts the power directly to the battery — and only when the engine is running.

How do I hook up two amps to one head unit with one pairt of RCA cables?

The one you choose to use depends on the features your car stereo has. You may be able to spot the audio jack on or near the stereo. Some vehicles like the Honda CRV have an audio jack in the center console in between the front right and left seats. You can use a simple 3.

These switches allow you to route a single audio source and sometimes more than one through a switching system that distributes the audio to various speakers or speaker pairs throughout the home. In this way you can choose, or select, which areas of the home you want to have audio. While simplistic, there are things you want to take into account when using these devices so that you use them properly and also maximize the way you distribute audio to various speakers in your particular application.

Typically, a speaker selector switch is placed after an amplifier or AV receiver, so that it can take a source—be it a radio, iPod or other streaming music source—and pass that on to speakers throughout your house. These are typically passive devices intended for use with already-amplified speaker-level signals. Options and Controls Speaker selector switches can range from handling two pairs of speakers all the way up to 8 pairs of speakers or more, but they all work in basically the same way.

They turn on and off pairs of speakers in the system, and they may or may not adjust the volume for each pair. More sophisticated models may even support more than one source, serving as a sort of matrix switcher for routing any audio to any pair of connected speakers. All you do is feed it a powered output and then choose which zones to send your audio to.

In this first diagram, we show a simplistic speaker selector configuration with integrated volume controls:

Adding 3 new wires to 1 fuse in fuse box in car

I decided to not cut up my PSU cables as i may need the computer it came from at some point, you will need to find the pins shown in the pic, they are on the connector that was originally on your motherboard, the cables should be green and black, any black ground connector will do the trick. Now a quick check, turn on your PSU and if the fan spins you’re all set for the next step. Wiring Your Amp So you have your amp ready? This is a good reference, it was made by BR14n https: I suggest using every except one, you need it later 12V rail there is that’s the yellow wires to ease the load.

As the picture shows you need to connect your ground on your amp to the black ground cable from the connector.

Feb 28,  · Connect the last battery to the amp(s) with a separate wire. Connect the batteries in the car with a large ground wire and ground it in metal. You don’t have to run it into the engine bay; any good metal ground will do. Be sure to put them in a sequence: first battery connected to the main in engine bay and last battery connected to the amp(s)%(17).

He is right that the main point of putting in the main power fuse is so that if there is a short the wire will not catch on fire due to excessive current. But the total current draw of your amp is 80 amps, If it draws enough to fry the main power fuse its close to frying your amp fuses as well. The way i see it, If there is a short its just that much sooner the fuse will blow. You can put a A in there but I would stick with an 80 unless you have problems then move up to 90 or A Click to expand I agree here as I manage a car audio shop.

We would prefer to use an 80 A ANL type fuse in-line to the battery. This means that the amp bridges internally.
