Can i connect a car stereo straight to a 12v car battery

How do you hook up a capacitor to an amp Step 2: Fiberglass a box for yourself example below. Connect the two halves of the fuse holder together, with the fuse installed. Secure the cable to the fuse holder terminal by tightening the small setscrew, using an appropriately sized allen wrench. But my headlights are flickering, what can i do? He has been writing since and has been published in multiple maintenance manuals and journals. Expert advice about auto repair that can really help you!

How USB Charging Works, or How to Avoid Blowing Up Your Smartphone

This is necessary when one is adding an amplifier to a factory head unit, since factory head units do not have RCA outputs to get signals from. It consists of a transformer and 10 to 20 watts a high-voltage resistor and connects to amp by using RCA patch cable. The amplifier in the head unit is being loaded by the resistor. It has also an adjustable gain feature to pull output. Most of the line output converters have wire to ground the transformer.

The crosoover selector should be set on LPF or low pass filter.

A voltmeter is a great accessory that will help you determine how well your car’s battery and alternator are working. The voltmeter will be able to tell you how the alternator is operating in conjunction with keeping the battery charged. Keeping an eye on the voltmeter in your car will tell you whether or not the alternator is bad. When the alternator is good the battery will remain at a constant 12V rating. The opposite also means that the alternator is bad. If the voltmeter shows that the amps is up to around 16 or more, it means that the alternator is not regulating the power well and needs to be replaced.

Connect two batteries in parallel — Part 2 answers the questions asked the most. Most people who want to connect two batteries together are trying to expand the battery capacity of their existing setup. One thing to remember, if you are going to install a second battery, you are going to have to start with two new, identical batteries.

When and How to Use a Trickle Charger April 18, A trickle charger provides a more sustainable charge than a quick jump start.

If you speakers have biwire terminals and you remove the jumpers then you can safely hook up an amp to each pair of terminals. This is called vertical amping bi-amping has an electric crossover feeding the amps. You will need a level control on at least on amp to adjust the amps to put out the same amount of power for the same input THX power amps are set this way with needing controls.

Can’t hurt to try it. The improvement will not usually be power related but in some cases you will reduce the im distortion generated by the speakers feeding back emf into each other through the crossover. That is why biwiring sometimes improves the sound. If the amps are identical then you can also get and improvement by making one amp left, the other right and reduce crosstalk generated in a stereo amp that is not dual mono.

How to install two amps

The old models shown below are manufactured by Pioneer and include the following features: C EQ has nine illuminated sliders. No car is acoustically perfect. This can mean that your stereo system does not sound as good in your car as it did when you heard and bought it in the shop. Furthermore, ordinary car stereos are often drowned at high road speeds by engine noise and the rushing of wind.

Learn about the benefits and best practices to using a trickler charger.

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. If you are using 2 different amps to 2 different components say like one amp to your 4 6″ speakers and the other amp to your sub then that is a totally different installation.

That means you will be needing some other “accessories” in order to install 2 amps like that. You might need a distribution block for the power and ground leads and more wiring. Also will your car provide enough power to your amps? If it doesn’t mostly likely you will need an upgrade in altenator or other. Also a w sub? What kind of sub is it? Are you refering to it as watts max or rms. Remember the RMS is more important then max.

If you use say 2. If you had used 10 mm2 wire you would be down to Basically if you size the wires according to the above table you will be fine. So, if you need a wire to take 7 Amps in a loom then you need only 1 mm2 wire, which is actually the cross sectional area – 1. Note that the bigger wires are made up of a number of smaller wires twisted together. The number of strands will often be more in a car – these tables are normally for domestic wiring which has thicker strands.

In NZ wipers must be two speed but some older motors may be single speed, so be careful.

This would add only 2. To advise on alternative strategies is a bit tricky as a I don’t know how you have your amps hooked up to the rest of your car system, and b I don’t know what your expectations are in terms of bass volume. From my point of view, if your system is hooked up correctly and working to its capacity, I would be quite satisfied with W of bass power inside a car.

But for all I know you might be a youngster wanting to build a ‘doof doof’ system that will annoy the hell out of anyone within a block’s radius of your car! Before spending any more money, you need to establish whether your kicker amp is delivering its full W before its overload trips. This is difficult to do without electronic instruments and knowledge.

Want to Connect an Amp to Your Radio

I’m playing folk music in a coffee shop. How much amplifier power do I need? Our rock group will be playing in a seat concert hall. How many watts will we need? I just bought some PA speakers. I want to play them as loud as they can get without blowing them up.

I know car manufacturers and aircraft companies crimp, but they use far better tools and fittings than you or I are likely to buy.

Battery Article Index Amps and Volts: This is a back to basic articles on understanding a batteries electrical ratings. Let’s take a real question from a real person: The battery that you show that would fit my unit is mah and 3. On the back of my PDA it says mAh and the volts is 5. Is the battery that you show for my unit the same? All PDA batteries have an electrical specifications that include its volt and milliAmp hour rating. These terms are abbreviated as we see in the following example: Volts — or V — are an electrical measure of energy potential.

You can think of it as the pressure being exerted by all the electrons of a PDA Batteries negative terminal as they try to move to the positive terminal. Amps — or A — is an abbreviation of Ampere, a 19th century French scientist who was a pioneer in electricity research. Amps measure the volume of electrons passing through a wire in a one second.

Overview[ edit ] Bridged or paralleled modes of working, normally involving audio power amplifiers, are methods of combining the output of two identical amplifiers to provide, what is in effect, a mono amplifier. Combining more than two amplifiers can be effected using the basic principles described, including the possibility of bridge and parallel modes in combination. Two identical amplifiers are most often encountered in a common case, with a common power supply, and would normally be regarded as a stereo amplifier.

Any conventional stereo amplifier can be operated in bridge or parallel mode provided that the common loudspeaker terminals normally black are connected and common to the ground rail within the amplifier.

If you have a houseboat or an RV, the wiring is the same as a house.

But if you insist on using an amp meter, here’s the information. The most important feature of the amp meter is that it is a low resistance high current device. It must be installed in series with an electrical load to limit current flow. If you were to wire the amp meter directly across the battery as you would with a volt meter the amp meter would immediately pass so much current as to fry the meter, almost instantly.

Some amp meters may actually be fused for internal protection. When properly wired in series with an electrical load the amp meter will monitor the current flowing in the circuit. This particular ammeter appears to be manufacture, so not exactly the correct period for MGA. However, since the ammeter was never standard equipment on the MGA, an aftermarket accessory could be almost any design hopfully not ugly.

If you have amp alternator you would need a amp meter. The direct reading vintage analog type dash mounted amp meter requires hookup wires sufficiently large to carry the full current in the circuit being monitored.

How to Wire an Ammeter into a Car

The current drawn isn’t continuous, it spikes and dips according to the music you play, and the volume. You need to overrate the PSU substantially, to allow for these spikes – not doing so will cause the power supply to burn out with extended use, or may constantly trip its overload protection mechanisms. Do NOT exceed As rexter said, the actual battery voltage is higher than 12V.

Just my Rockford amp is watt peak power and RMS.

Previous topics in the series include: You never want your vehicle battery to be doing the work that the secondary batteries should be doing. The house battery solenoid needs to be energized all the time while the engine is running. If Possible Use the Fuse Panel to Power Your Solenoid Your vehicle should have a fuse panel under the hood or behind a plastic lid under the dashboard. The male half of the spade terminal will plug right into a vacant fuse slot on most vehicles.

The solenoid you buy might have a 4th connection for a ground. Inverters change the 12 V direct current from the batteries to V alternating current AC used by your appliances. Many electrical devices will state they only require watts. In reality their start up surge will take times more than that. The wiring between the two batteries, and also from the batteries to the inverter, needs to be automotive battery cable size. Two house batteries connected in parallel in my van Your inverter is a heavy electrical draw.

For the batteries to discharge together equally, the cables connecting the batteries to each other and to the inverter should be made with the same type and size of cable.
