If power is red wire, ground is black, and remote is blue, then you will have an easier time keeping track of your wires and what they connect to. Otherwise, if one amp fails, you may find yourself overwhelmed and needlessly tearing out wires.

Connecting 2 amplifiers to one set of speakers: making an amp/speakers selector switch |

Determine whether you need multiple batteries and capacitors. If you have a w amp playing three w subs, but they really sound weak, then it's time to get more power. Alternatively, play the bass as loud as you can and see if your dome lights dim or not. If they barely flicker, then your power is manageable, but if they almost go dark with each bass note, then it's time for more power. There are three ways to go: Capacitors are usually small cylinders that come with a digital display showing your voltage in your car.

They are rated by Farad's and the higher they are, the better the cap can store and release volts. They are for very minor power problems and simply add a more sophisticated look to an audio system. A 1-farad capacitor could potentially cost hundreds of dollars and not solve any power problems. The ideal voltage for a car audio system varies. For a low-end system, For average systems, Anything below 9 is extremely bad and should not be used until more power is added.

You may completely drain your existing car battery and render it useless. The cheapest way to fix a major power problem is with more batteries. Although wet cells can be used, they could spill battery acid in your car if they leak. Dry cell batteries are a better choice if you can afford them. Dry cells have no battery acid and are extremely safe in a vehicle.

To install multiple batteries or capacitors , connect the main battery in the engine bay with the another one elsewhere in the car that has a large, low gauge wire like a 4 or 2. Systematically connect the next battery by running a wire from the first battery power, to the second battery power, and so on until you reach the last battery. 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. Be sure to put them in a sequence: By getting a larger alternator that puts of more amperage, your battery will be continuously and quickly charged.

Whenever massive amounts of power is needed, it's directed from the alternator much more than the battery, giving you more power. A good amp alternator can really make a difference in sound quality and bass. You just have to find it for a good price and have it installed. Check and double-check all connections. Before you turn on your car, make sure all connections are solid and correct.

Make sure all amps are properly grounded and REMnd. Excess wire should not be sticking out and relatively close other wires of different charge.

Use fuses for all battery to amp connections. If you blow a or amp fuse just by listening to music, then check specialty stores for and amp fuses. Finally, use electrical tape your best friend when dealing with wire to cover up exposed wire. A thin strip can stop your entire system from being nothing but overpriced junk. It all depends on what kind of car you have. Some dashboards have clips were you can pop your dash off and other cars have some screws you need to take off before you pop it off and it's the same with door panels.

There will be some screws once you take them off lift up on the panel and pull it out. Not Helpful 1 Helpful 1. I want to upgrade my car sound system from a 10 inch with 2 amps W to two 15 inch subs. How do I do this?

Warnings The simplest, but ill-advised, method for connecting multiple amps is to connect the wire to the amp, and through the same terminal, have another wire extend out to the next amp. However, many complications can arise from using one wire to power many amps.

How do you wire 2 amps together ?

Unless you really need to, do not get multiple batteries or capacitors. This is by far the most dangerous aspect of any high-end car audio system, as it can literally ruin equipment if not properly installed. Dry cell batteries are better than wet cell batteries because the latter could spill battery acid in your car if they leak.

Dry cell batteries do not contain battery acid. Cars were never meant to hold 10 speakers bass and vocal and as such, cars are ill equipped to deal with the major power demands that come with thousands of watts of power. If your amp does not have a good protect system, it could easily blow because of a silly mistake.

Car Radios and Sound Systems In other languages: I would like to create a selector-switch box for 3 amplifiers to my set of speakers.

The set of speakers includes: Adding switches in the signal path can always degrade the sound a bit. But with switches of this type any change in sound should be minor or even inaudible. My way of switching is safe for both amps and speakers, so it can be used also in your scenario. To accommodate 3 amps and 2 pairs of speakers you can daisy-chain 3 switches made according to the same principle as my switch. Or actually 2 switches like mine to switch between the amps and one cheap, ready-made speaker selector, because switching between speakers is a less sensitive issue and you can have both pairs of speakers playing at the same time and, unlike amps, they can have common ground.

Unless one of your amps does not tolerate that, in that case it is better to use my safer switch. Remember that my switches can work both ways, this means that they can have either 2 inputs and 1 output or 1 input and 2 outputs. Amp A and Amp B are connected to the inputs of switch 1. It selects between Amp A and Amp B.

Amp C and the output of switch 1 are connected to the inputs of switch 2. The output of switch 2 is connected to the input of switch 3. The outputs of switch 3 are connected to Speakers A and Speakers B. With the above system, switches 1 and to select amp A, B or C only one at the time. This one can allow to select both speakers and have common ground if ALL your amps can handle that. That covers amps and stereo speakers.

Now to your specific situation. I understand that the subwoofer is not important because you only use it with the surround receiver and you only need to connect speakers A and B to two receivers. There are two possible scenarios:.

You use either speakers A or speakers B but never both at the same time with each receiver 2. You use both speakers A and speakers B at the same time with each receiver. Also, one of your amps is a stereo receiver the same signal goes to speakers A and B and the other amp is a surround receiver different signal goes to speakers A, different to speakers B.

That is also important. That means that even if you ALWAYS use both speakers A and B, they cannot be connected to the switch in parallel, because only the stereo receiver uses a parallel connection.

How do you wire 2 amps together ?

The surround receivers actually works as two separate amps front speakers amp and rear speakers amp. I understand that in the case of the surround receiver speakers are connected to front and rear outputs, and not to front A and front B outputs that would be a very different connection and actually similar to using a regular stereo amp. In that case, the best solution is to use two switchers like the one I described. One switch switches speakers A, the other switches speakers B. But it does mean two times the work, materials and time needed to build the switcher. The two switches and corresponding speaker binding posts can be fitted into one enclosure, obviously it would need to be larger.

This solution 2 separate switches for speakers A and speakers B will work perfectly fine in other scenarios, for example with 2 stereo amps that use speakers A and B, or with a stereo amp and a surround receiver where the speakers are connected to front A and front B outputs of the surround receiver as opposed to its front and rear speaker outputs. But in some cases a simpler solution would suffice. Very happy with the result.
