How do i hook up the remote wire on my car amplifier?
So you want to keep the factory amp? I wouldn’t suggest that. I’d recommend getting rid of the factory amp altogether, they’re usually not the best, and it would be difficult – if not impossible – for them to work together.

What do you need to hook up subwoofers in your car
One of the most overlooked aspects of a high-powered auto sound installation is its effect on a cars electrical system. No amplifier, no matter how sophisticated it is, can change the laws of physics. Energy can neither be created nor destroyed; it can only be changed from one form to another. This is exactly what an auto sound amplifier does:
The RMS power on your amp should always match the RMS power rating on your subwoofer and speakers. The higher the RMS rating, the louder and cleaner your music sounds. Peak power: The wattage a car amplifier has available for brief sound increases.
Sometimes the amp itself really is at fault. Here are a few common problems and what can be done to troubleshoot, as well as fix them my fixes are the most common. They are not definitive in any way. Your amplifier could have a completley different problem, though it is unlikely: Amplifier does not turn on. Rule number one in amplifier hook up is to make sure the amplfier has a good ground. This means that it is secured to bare metal that is clean, rust-free, and tight.
Is the remote wire hooked up? After that point, if the problem still exists, you’re probably looking at bad parts in the PSU power supply unit. The majority of the time, it’s because mosfets are blown. It is never a bad idea to try hooking up the amplifier in a different car or taking it in to be tested just to be sure. Sometimes you can open the amp up and find physically fried components. For space constraints, I’ll leave it at that. Amplifier goes into protect.

I have a Pioneer VSX receiver. As It does not have a Phono input I have connected my turntable to a Pre Amp and then to a spare input on the receiver. That works fine. The Sub Woofer output on.
Whether it’s an installation that might not have gone as planned, or a random problem that comes out of nowhere. Here is a list of your common car stereo problems, symptoms and solutions to help get your stereo up and running! Many Jeeps and Chevrolet systems have a data signal wire that carries a very low voltage signal that tells the OEM Head Unit when to turn on, however; it is not compatible with aftermarket units. If you have a voltage meter or a test light, test the ground black , constant 12v yellow , and accessory 12v red wires to make see if you have the correct voltage in the correct wires, as well as a good ground.
Constant will always be 12v, whether or not your car is on. Make sure to use your ground, as well as another ground like the frame or body of the car while testing your constant and accessory to test that you have a good ground. If you find that one of your power wires or ground wires are not correct, check your vehicle wire diagram and make sure you have the correct corresponding power and ground wires. After finding the location of the fuse, pull it and make sure that the leads are not corroded and that the fuse has not been broken or popped.
Most aftermarket amplifiers have a protection from low and high voltage. Vice versa, if your battery is low and the amplifier is not receiving a constant 12v, it will enter protection mode. Amplifiers will also enter protection mode if there is a short somewhere. If you have a signal RCA wire that is shorting out, this could be your problem so check to see if your RCAs are in-tact and not shorted.
Also, if one of the output channels are shorted out, or you have a blown speaker, many aftermarket amplifiers will enter protection mode. Disconnect all output channels and see if it will return to normal operation.
LOADS Amplifiers are designed to power a specific “load”, meaning a speaker or set of speakers having a specific “AC impedance” measured in ohms. Impedance resists the flow of electric current so the higher the speaker impedance the less current the amplifier has to supply. Conversely, the lower the impedance the more current must be supplied.
As far as charging the batteries I would not suggest hooking them up to your car battery for charging, as you could damage your car battery by the alternator overcharging it. The proper way to charge an additional battery pack off an alternator would be to use a Battery Isolator, such as our Quick Power Amp Battery Isolator Bi
Vibe 17 Test conditions: This generally causes no problem because the increase in current is still below the current normally drawn by other amplifiers. There is at least one very popular brand of amplifier that draws as much as ma of current when the amplifier fails. This is enough to damage the remote output switching transistor in the head unit if the fuse is missing or is of the wrong value.
A relay in the remote circuit will completely eliminate the possibility of damaging the head unit in this situation. The input circuit sometimes called the ‘front end’ generally employs a noise cancelling circuit which compares the signal on the center conductor the audio signal to the signal on the RCA shield which generally has little or no signal and is only used as a reference and amplifies the difference between the two.
The input impedance is the impedance that the signal source ‘sees’ from the center conductor to the shield on an unbalanced input circuit. If the input circuit uses a mini DIN type connector, the input impedance could be measured from one signal terminal to the other or from the signal terminals to the shield ground. Ideally, the impedance should remain constant throughout the audio band. More than a few amplifiers employ some sort of high frequency noise filter which will cause the input impedance to fall slightly at the upper end of the audio spectrum.
These filters are designed to reject high frequency noise from the amplifier’s switching power supply.

Before cutting any wire, a good diagram is in order. Draw a diagram on plain white paper with wire gauge noted and colors identified. Each component must be labeled. This wiring diagram will stay with the car so make it neat and easily readable. Pictured is my wiring diagram for installing two fog lights with fuses, a switch, and a relay.
To set LPF filters on your subwoofer amp, an easy way is to disconnect the RCA’s to any amplifiers that are not powering your subs. Be sure that all equalizer settings (bass, treble, front/rear, etc) in your head unit or at “0” or flat.
By Doug Aamoth January 7, Q: Without spending a fortune, is there a way I can connect my phone to the stereo so I can listen to music? Yes, you absolutely have a few options — some more expensive than others, and one that might actually cost you next to nothing. That thing is looong gone by now, right? For a couple sawbucks, you can add a Bluetooth connection of sorts to your stereo.
Your phone connects to the transmitter via Bluetooth, and the transmitter then relays the audio from your phone to a blank FM station on your radio. Several of these products feature microphones so you can make and take hands-free calls as well. Your best bet here would be to look for a local car audio place that sells stereos bundled with installation. Make sure to check whether the mounting kits and wiring kits are included in the price of installation.
Or do some research and learn to install the stereo on your own. Doug Aamoth lives in Boston and has spent more than two decades in the technology industry, working for consumer electronics retailers, support centers, startups, cybersecurity providers, and media companies.
How can i connect a sencond car battery to my sound system?
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.
Apr 25, · All you have to do is connect your smartphone to the car stereo via the AUX port, using a “male-to-male” ” jack connector. Plug in one end to your smartphone and the other to the AUX port.
Wiring Multiple Speakers Calculating Impedance Loads This calculator is intended to help you determine the impedance of a speaker or subwoofer wiring configuration. There are many ways you can connect multiple speakers together. The most common and best way is to connect them in parallel. You do this by connecting the positive speaker wire from the amp to the positive terminal on the first subwoofer. In the picture below, one channel is shown.
Then, you connect the positive from that first subwoofer to the positive of the next subwoofer. You can connect as many speakers together like this as your amplifier can handle. Before you attempt this, be sure of what your amplifier can handle. If it says it can handle 2 ohms stereo, don’t connect more than four 8 ohm woofers or two 4 ohm woofers per channel. The formula above is for multiple subwoofers with the same impedance.
With the wire fed into the cab, I attached it to a 6-way fuse-box A which I mounted on an existing screw. This means I can take various fused feeds from the leisure battery. I had to make a small metal bar to connect the high-amp live feed to the six terminals on the fuse box and I used self-tapping screws into spade connectors. Obviously I will need to remove the glove box to check or change these fuses but I could not find anywhere else suitable that was out of the way, and it also means all the wiring will be well hidden.
If the jump works and your car starts, don’t shut off your engine! Drive around for at least 15 minutes to recharge your battery. If the car won’t start the next time you use it, the battery isn’t holding a charge and needs to be replaced.
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. A 30 amp meter would need a pair of 10 gauge wires. A 60 amp meter would need 8 gauge wires.
How To Hook Up A Crossover To Your Amp
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.
