Will It Work: Car Amp Plugged Into A Wall?

Only a few years ago there were very little choices for electric vehicle charging equipment. When I got my MINI-E in 2009,;BMW;partnered with;ClipperCreek;to supply the;home charging station, or as BMW called it, the “Wallbox” to charge the fleet of 450 MINI-Es in service in the US. Tesla also reached out to ClipperCreek back in 2008 to supply the charging equipment for the initial Tesla Roadsters. Neither company really had any choice, because at the time ClipperCreek was pretty much the only company that could deliver this specialized EV charging equipment.

One example of the new, lower-priced units is the AmazingE. The AmazingE has been available for a little over a year now, and seems to have a relatively high customer satisfaction rate. It has an Amazon rating of 4.8 out of 5 stars, and the reviews on many online EV forums are mostly satisfactory.

How To Wire A Car Amp To A Wall Outlet

If you’ve got an MP3 player and a decent car stereo, it’s easy to get by without an equally powerful home setup. If you’re in that position, you might occasionally want to use your car amp in the house to drive a set of speakers. Car amplifiers run on 12V DC power and your wall outlet puts out 110V AC, so making them play together nicely takes a bit of persuasion.

How To Properly Hook Up A Car Amplifier Inside The House

Hello everybody, recently i bought car amplifier for repair and decided that im gonna replace my Sony XM-4020 that i have been running as my subwoofer amplifier for a year now. I took this opportunity to write instructable on how to properly hook car amplifier for use inside of your house and what you should be careful about.

There are many reasons why you would want to use car amplifier, but if you can choose between proper 120v-240v amplifier and car amplifier i would suggest you to pick house amp, its power supply is well designed and you will get proper power output out of it. Car amplifiers are mostly rated at 14,4V and lower impedances while some home amplifiers can only go as low as 4 ohms. Since you will be running it off 12V power supply you might not get as stable power as you would in your car.

If you however still choose car amplifier then continue reading as i will try to provide as many information about it as i can.

I’ve been running car amplifiers in my room for 6 years or so, it used to be hard to get proper amplifier and if u were like me you probably had spare ATX power suplies so you could save a few bucks on that. These days it’s much cheaper and easier to just get 24V chip amp from ebay and have decent setup. Even designing and building your own, internet is full of schematics that are just waiting to be built.

Dont Spend A Fortune Installing Charging For Your New Electric Car

The size of your circuit breaker box and service will decide how much it costs to add an electric … car charger.


Earlier, I wrote a guide to help you , particularly with the Tesla Model 3. After you get your car, you want to install home charging for it where you park it If you cant install any charging at all, because you park on the street or in an apartment parking garage, then you face a challenge. If you can charge at your office thats great, though not without other issues. If you cant do either, I dont currently recommend purchase of an electric car, at least for now.

If you have newer service, fear not, you dont need to change the panel, and you can just add a new circuit. If the wire is not that long, getting that plug may not cost that much. Sadly, many see a more expensive estimate. How can you get away from it? The answer is that while its nice to have enough power to recharge a car from zero to full in one night, you dont actually need nearly that much.

Remove The Connection With Speaker:

When there is the use of stereo then definitely you need speakers. Moreover car radio connects with the speakers in the car so there is a need for the removal of speakers with help of screw gauge or screwdriver.

Some speakers do not remove connection with a screwdriver because they are immersed and only can disconnect with the help of a drill.

When installing an amplifier, every car will present its own challenges that you will need to overcome. This guide will help you to do it correctly, and safely. When dealing with a car’s electrical system you need to always have fail-safes. Those being the fuse located within 18″ of the battery of the car, as well as the fuses that are built in to many amplifiers. NOTE: Just because the amplifier has fuses on it does not mean you do not need one near the battery!

Determine The Amperage Rating Of Your Car Amp

First of all, determine the amperage rating of your car amp. You can do that by looking at the input power specifications mentioned in the user manual of the amplifier. If you dont have the manual or cant find it, take the internets help. Search for this term on Google:

The current draw of in amperes.

You will find the amperage rating from the official website or reliable car audio forums.

What’s So Special About That Plug

The SAE J1772 charging plug is as inelegant as its name. And the five ports that connect to your car might seem complicated, but they’re actually pretty straightforward.

1 AC power, just like the power plug for your TV.

2 Proximity detection. This is simply a mechanical switch that makes sure you’re plugged in all the way.

3 Ground wire.

4 Communications, used to relay data between the car and the charger about how much current is needed.

How To Avoid Paying For Electrical Work You Dont Need

  • Bundled charger + installation price? Be suspicious. If you already have a 200-amp panel and it has enough space, getting an extra 240 outlet installed is typically one of the simpler jobs an electrician will ever do. Dont necessarily accept a bundled rate for the charger + installation. Get a free quote from an electrician you trust and shop around. Make sure they understand exactly what kind of work you need.
  • Beware unnecessary permits. Level 2 chargers can be hardwired to your panel or simply plugged in to a 240V outlet. The Permit for hardwiring can be more expensive and complicated. Hardwiring is typically only required for outdoor charger installation. Indoors, its ideal to just plug in your charger. Choose a charger with a wall plug option if youre going to be charging indoors.
  • Does that quote include permits? Some installers cover permit costs, some dont. Make sure quotes include any permit costs for an apples-to-apples comparison. Also know whether theyre going to handle the permitting process for you or not.

How To Use A Car Battery To Power A Guitar Amp

Whether you want to rock on the go or just want to play outdoors for a while, running a guitar amplifier off of a car battery isnt difficult or too expensive. All you really need is to convert the DC power from your vehicle into AC, which is the kind that comes from your wall. Most car batteries are strong enough to power a 50- or even a 100-watt amplifier, though you will drain your car battery after a bit.

How To Hook Up A Car Amp Inside The House To A Wall Outlet

How to Connect a Car Amp to a Wall Plug? (2021 Edition)

If you’ve got a car amplifier you’d like to use in your home, there’s one major obstacle to overcome: how to power the amplifier. Wall outlets provide 110-volt AC power, but amplifiers require 12-volt DC power. You’ll have to do a little extra wiring, but the problem is not insurmountable.

Look up the input power specifications for your amplifier, using the manual or the manufacturer’s website. Find the specification for current draw in amperes.

Purchase an AC to DC power inverter. Make sure the inverter can produce a 12-volt DC output at the specified amperage rating.

Cut a length of 10-gauge red wire, a length of 10-gauge black wire and a length of 16-gauge wire, each long enough to reach from the amplifier to the inverter. Remove 1/2 inch of insulation from each end of the wires with your wire strippers.

Loosen the power terminals of the amplifier, marked “+” and “-“, with a screwdriver. Loosen the REM terminal of the amplifier with a screwdriver.

Slide the ends of your wires into the loosened terminals and tighten down to clamp the wires. Insert the red wire into the “+” terminal, the black wire into the “-” terminal and the 16-gauge wire into the REM terminal.

Loosen the terminals of the inverter. The method and tool will vary by brand. Slide the black wire into the “-” terminal and tighten. Twist together the ends of the red wire and the 16-gauge wire, slide them into the “+” terminal and tighten.

How To Choose The Right Power Supply Unit For Your Amp

An AC to DC power supply units can be bought either online or from an electrical store. However, you need to check a few things before buying the power supply.

Choosing the right power supply unit for your amplifier depends greatly on how much electrical current your amp will draw, and on whether youre going to push the amp hard or push it softly.

Thats the reason why the power supply must produce at least 12-volt DC, and that its amperage rating matches the specified rating of the amp.

Essentially, there are 2 basic ways to go about choosing a power supply for a car amp:

  • Getting a decent power supply that can output enough voltage and current in order to power your car amplifier. This is a good option if youre not driving the amp really hard .
  • Estimating the amplifiers current draw based on its power rating .
  • Getting The Right Components

    Since most car amps dont come with any wires or cables, youll typically have to buy the necessary components yourself, either separately or as part of an amp install kit. If you go the former route, then you should start out by checking your manual to see what gauge power and ground cables your amp requires.

    You can also take measurements to see how long a run there is between your battery and the location where youll be installing your amp. While youre at it, you can check the distance between that location and your head unit to see how long your remote turn-on wire needs to be. Finally, you can determine whether you need traditional speaker wires or RCA cables by looking at whether your head unit has line-level RCA outputs. If it doesnt, then youll just be using speaker cables to hook into your ampprovided it has speaker-level inputs.

    After youve put together a list of all the cables and wires that you need to complete your installation, you have to go through the actual process of finding and buying them. Power cables and speaker wires are typically available in bulk, although you can usually buy power cables that are cut to the specific lengths that you need. RCA cables are also available in a variety of lengths, although you should try to keep them as short as possible so as to avoid tangles and kinks.

    What About The High End

    This advice is for those with a 100 amp service in their house. If you have larger service, like 200 amps, there is no reason not to install a nice circuit to a 50 amp plug, known as the 14-50 plug the same one big RVs use. You cant use all of it, but you might buy a bigger electric car in the future, and you might even buy two electric cars, and wish you could get 60 or more amps. Price out getting bigger wire than you need, it may only add a modest amount to the price of your install. Tesla Wall Connectors have a nice feature which allows them to daisy chain and share the power between two of them when you have two Teslas.

    Even if you go for one of the cheaper plugs described, like the 6-20, you should run thicker wire to it able to handle 30, 40 or 50 amps. Price it out. If you do, and later you do upgrade your house service, you wont need to rewire that circuit to get that maximum power.

    Of course, there can be other reasons to increase the service on your house. Its a bit safer, and can offer room for other expansion you might do in the future, such as more cars, air conditioning, a hot tub and other things. All those reasons might justify the upgrade the main point of this article was to examine when the car alone doesnt need it.

    Setting The Gain And Bass Adjustments

    The problem with having sound adjustments on both the stereo;and the amplifier is that settings can be all over the place and one can affect how the other produces sound to your subwoofer.

    I recommend doing the following:

  • Turn off all bass boost or equalizer functions on the stereo or set to mid-level or zero.
  • Turn off any bass boost controls on the amp or turn to the minimum level
  • Set the amp gain to its minimum
  • Most well-designed amps like the popular Alpine MRV-F300 feature flexible crossover controls you should use. With them, you can get clean, low-distortion music power at high volume. Surprisingly very few people use these features to their potential!

    Play some music youre very familiar with and that you know should have good bass sound at a moderate level. Then with a small screwdriver or screwdriver bit that fits adjust the gain until bass performance is at the level you enjoy.

    Dont forget that when an SUV hatch or car trunk is closed the sound will be changed somewhat as opposed to when the door, trunk, and/or rear hatch are closed.

    In case the stereo has insufficient bass or your system still doesnt sound quite right, try using the bass boost on your amp if available.

    A bass boost typically works boosting bass response around a fixed or adjustable frequency near 50Hz for example. These can sometimes add some extra thump and bass extension to your audio system.

    How To Connect A Smartphone Or Other Device To A Car Amp

    Be aware that headphone jacks can be a good or bad audio source depending on your particular device. Even though theyre usually not quite as good as RCA outputs/AUX output jacks, Ive had pretty good experiences doing using this with brand name smartphones or tablets.

    In fact, I use this method to test a car amp at home.

    You also use an affordably-priced Bluetooth receiver for around $25 from places like Amazon. They offer a direct line output jack or RCA jacks for this very reason.

    Be sure to get a decent brand as the generic/no-name brand models tend to have sound quality problems and can produce odd noises between music tracks playing on your phone, for example.

    Charging At Slower Level Two

    A Level Two circuit runs at twice the voltage and usually at higher current. In fact, you can install these able to do up to 80 amps. For most people though, you dont need nearly that much. You will be very happy with enough to restore about 60% of your battery, because your typical daily cycle should run from 20% to 80% full. On a 240 mile Tesla Model 3, you can get that in 8 hours with just 5 kw, which is what you get from a 30 amp plug, the same one that runs your dryer. Such a circuit is going to fully restore you on almost any day you drive, particularly if you have more than 8 hours at home. You really dont need it faster. The regular range Tesla cant take more than 32 amps in any event but you just dont need even that. If you can get it, of course you should take it, but you should not spend thousands to get that extra boost.

    Your electrician might tell you you need a new panel for a 50 amp plug, but that you can put in a 30 amp or 20 amp without a new panel which can save you a fortune.

    If you have a truly dedicated plug then in many cases an electrician can, for not much money, replace a regular 120v socket with a 240v stocket for twice the charging rate, changing the plug and breaker as long as the wiring is rated for the higher voltage. Ask about that it can almost surely fit your panels load maximum.
