How To Install 2 Amps And 2 Subs

1. 1

   Have all components, tools fix and checked. This includes drills, drill bits, island keys, and wrenches. But nigh importantly, make sure you have the correct wires for the job.

2. 2

   Gather the necessary materials. Call back that each amp needs a ability, a ground, and a REM (remote) wire going through them.

3. 3

   The best way to connect multiple amps when it comes to REM, is through one remote wire. Since the remote wire basically tells the amp when the radio is on, all amps can exist connected to the same remote wire.

4. 4

   All-time thing to do is for power wire is connect each amp with a separate power using a distribution cake, which is essentially a casing that allows one wire to supply ability to multiple wires (one wire from the battery goes in and three wires tin come up out). ^[1]

5. 5

   Connect one power wire (wire that connects from the bombardment to the amps) to your distribution block. Your thickest or everyman gauge wire should be your main ane.^[2]

6. 6

   Have the the remaining wire go to each amp as a power wire. ^[3]

7. vii

   Make certain each amp has its ain separate footing. just ground information technology to whatsoever piece of metal. Wire tin burn and melt if too much current is running through it then one wire is your best bet.

   Know your amps' and sub woofers' limits. This is crucial to achieve perfect precision with 4, 6, and eight or more than sub woofers.

   • An amp that is rated at 1000w RMS (Root Mean Square, or the boilerplate watt the speaker is intended to receive and play with) set for i ohm can power two two-ohm subs rated at 500w RMS.
   • That same amp can ability four 4ohm subs and and then forth. But the more subs an amp is placed on, the less power it tin give to each individual sub. This is not necessarily a bad thing if you lot have a 2000w RMS amp and two 600w RMS subs. In fact, you always want the power from the amp to be slightly higher than what the sub(s) requires; a 1000w amp will work well with a 7 or 800W RMS sub.
   • Simply make sure that the sub'southward elevation power is rated above 1000w. If rated under, brand sure your amp's level is non too loftier as you can impairment the sub.
   • If you have a actually powerful amp that'due south 3000w RMS or higher, and so you can really power multiple subs at once without whatever problem. Just brand certain the subs don't combine to read at 0.5 ohm (a dangerous level for an amp, unless it specifies that information technology tin run at that low ohm level) and all your wires are properly connected and wired.

2. ii

   Connect all subs to the same terminals in the amp. Withal, depending on whether you lot wish to connect them in serial or parallel or bridge the amp, y'all may only utilize two terminals. Refer to your amp's diagram for more specifics.^[4]

   These are besides known equally "door speakers", "vocal speakers", "6 by v" or "6 by 9" and more. If you're trying to install more than than what your car originally came with, the aforementioned rules should be applied to those of subs.

2. two

   Brand sure your 4-channel amp can play them all without being so powerful that they damage the speakers. Because most speakers are rated to 8 ohms, y'all can generally connect many speaker to 1 amp without any problems.

3. 3

   Connect all mids and highs with the aforementioned power and ground. All cars have pre-wired powers and grounds that go through the doors and the back dash. It would be foolish to run multiple wires through your door and dash to play multiple speakers with such low wattage.^[5]

4. 4

   Connect all speakers through the adjacent speakers that are pre-wired through the automobile. Just brand sure the power and ground are positioned properly throughout the process.

1. 1

   Follow the full general rule: for power, footing and speaker wires, the lower the number and thicker the wire, the amend. (Remote and RCA wires are e'er small.) People tend to underestimate the amount and size of wires that they need when installing many components in a auto sound systems.^{[half dozen]}

   • If you lot have the chance of using half-dozen-gauge wires as your ability instead of viii, then do and so. It may save you lot a lot of time and money.

2. 2

   Ever use the biggest merely almost appropriate wire in instance you decide to upgrade your audio system.

   • If you previously had a 1000W organization, then that 8 estimate wire may work. But if you upgrade to more than powerful amps and subs, say 3000w, that 8 approximate will burn and melt in no fourth dimension at all. So you will have to remove information technology, and rewire the car with 2 estimate wire.
   • If you take a feeling that yous may get bigger in the hereafter, chose bigger wire.
   • Multiple Wires tin can lead to ground racket. People with many components and wires running through their car can easily end upwards getting "footing noise," which is the whining sound that plays through your speakers and rises and falls with the rev of your engine.
   • Although there are many products that claim to reduce basis racket, the best method is positioning the main power wire and RCAs/4-channel amps as far away from each other as possible.
   • A large power wire can create massive amounts of electromagnetic interference that tin be picked up by RCA'due south of a 4-channel, and subsequently relayed back through the radio and mids and highs as ground noise. Ready the problem by running the power wire to the left of the commuter side seat and placing the amp and RCA's under the passenger seat.

3. three

   Brand everything color coded and bully.

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

   Advert

1. 1

   Determine whether you demand multiple batteries and capacitors.

   • If you have a 3000w amp playing three 1000w subs, simply they really audio weak, and so it's time to get more ability.
   • Alternatively, play the bass as loud equally you lot can and come across if your dome lights dim or non. If they barely flicker, then your power is manageable, only if they almost go night with each bass note, and then it'due south time for more than power.

2. 2

   There are three means to go: capacitors, alternators, and batteries. Capacitors are usually small cylinders that come up with a digital display showing your voltage in your machine. They are rated past Farad's and the college they are, the better the cap tin store and release volts.

   • Be warned: many capacitors are nada more than expensive voltage meters. They are for very modest power problems and simply add together a more sophisticated look to an audio system. A 1-farad capacitor could potentially cost hundreds of dollars and not solve whatever power issues.
   • The ideal voltage for a car audio organization varies. For a depression-cease organization, 13.5-xiii.vii is only fine. For average systems, 13.8-14 is good, but for high-finish audio systems, 14.4 and above is where y'all want to be.
   • Your voltage should not drop below 12 volts, as that's an indication of a big power trouble. Anything beneath 9 is extremely bad and should not be used until more power is added. You lot may completely bleed your existing automobile battery and render it useless.

3. iii

   The cheapest fashion to ready a major power trouble is with more batteries. Although wet cells tin can be used, they could spill battery acrid in your automobile if they leak. Dry cell batteries are a better option if you can afford them. Dry cells have no battery acid and are extremely safe in a vehicle.

4. 4

   To install multiple batteries (or capacitors), connect the master battery in the engine bay with the some other i elsewhere in the motorcar that has a big, low approximate wire (like a 4 or 2). ^[7]

5. 5

   Systematically connect the side by side battery by running a wire from the first battery power, to the second bombardment power, and so on until y'all achieve the terminal battery. ^[8]

6. 6

   Connect the last battery to the amp(s) with a split up wire. Connect the batteries in the car with a big footing wire and ground information technology in metallic. You don't accept to run information technology into the engine bay; any practiced metal ground will practice.

   • Exist certain to put them in a sequence: offset battery connected to the main in engine bay and concluding bombardment connected to the amp(due south).

7. 7

   You can upgrade your alternator, if you lot don't want numerous batteries or capacitors to take up space in your car.

   • By getting a larger alternator that puts of more amperage, your battery will exist continuously and quickly charged.
   • Whenever massive amounts of ability is needed, it's directed from the alternator much more than the battery, giving you more power.
   • A good 220-amp alternator can really brand a deviation in sound quality and bass. You only have to find it for a good toll and have information technology installed.

1. one

   Check and double-check all connections. Before y'all turn on your car, make certain all connections are solid and right.

2. 2

   Make certain all amps are properly grounded and REMnd. Excess wire should not be sticking out and relatively close other wires of different accuse. Use fuses for all battery to amp connections. If you blow a 60- or 80-amp fuse merely by listening to music, then check specialty stores for 200- and 300-amp fuses.

3. 3

   Finally, utilize electrical tape (your best friend when dealing with wire) to cover up exposed wire. A thin strip can stop your unabridged organisation from being cipher simply overpriced junk.

  How do I remove the front dash and door side panels?

  

  Information technology all depends on what kind of machine you have. Some dashboards accept clips were y'all can pop your dash off and other cars have some screws yous need to take off earlier you pop it off and it'due south the same with door panels. There will be some screws once you take them off lift upwards on the panel and pull information technology out.

• The simplest, merely ill-brash, method for connecting multiple amps is to connect the wire to the amp, and through the same final, accept another wire extend out to the side by side amp. Nonetheless, many complications can arise from using one wire to ability many amps.

• Unless you really demand to, practice not get multiple batteries or capacitors. This is by far the virtually unsafe aspect of whatsoever loftier-end car audio system, equally information technology tin can literally ruin equipment if not properly installed.

• Dry cell batteries are better than moisture 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 concord 10 speakers (bass and vocal) and as such, cars are ill equipped to deal with the major ability demands that come with thousands of watts of power. even with one or two batteries, caps, or even 2 alternators, you lot may non produce the amps/volts that your cars original electric arrangement + sound organization crave to keep it running and major damage tin can occur to your original electrical equipment because of lack of power. wires may burn, existing batteries may die, alternator might exist shot, and the car may accept cranking problems or non crank at all. if you wish to go through with adding a serious sound system, go ready to shell out the money information technology takes to power it. "bass heads" may accept iii alternators, v batteries, and 5 caps all in one car just to proceed it properly powered (and a professional automobile charger just it case it still dies). resulting in close to $2000 in ability equipment merely to keep the car on! the more components you put in a motorcar, the more money you must spend on power to go along it running

• A big problem many people make is accidentally connecting the footing to the 12v power in the amp and vice versa. If your amp does not have a skilful protect arrangement, it could easily blow because of a empty-headed mistake.
