How to Properly Install a Subwoofer in Your Car

On this information, I am going to current you the complete course of placing in an amplified subwoofer proper right into a car. After you’ve got gotten your subwoofer system prepare, you will hear considerably higher sound out of your stereo.

This course will work with most stock stereos, and all aftermarket stereos. It could be modified to work with all stock stereos, nonetheless it is doable you will need just some additional elements. I am going to current you methods to try this with an aftermarket head unit (stereo).

When you’ve got a take a look at the photographs, perceive that I am using an amplifier that is too small for the subwoofer. It is for demonstration capabilities and it does not sound just about pretty much as good as a result of it should. In numerous phrases, my car desires a a lot greater amplifier to help the subwoofer.

Step 1: Elements

So what will now we have to try this?

-Subwoofer area
-Subwoofer speaker (see subsequent step)
-Amplifier (see subsequent step)
-Wiring bundle (or each of the following)
-10 Gauge or thicker, 20 foot insulated wire (for power)
-10 Gauge or thicker, three foot insulated wire (for ground)
-18 or 16 Gauge, 15 foot wire
-RCA cables, 15 ft or longer (you need 2 or one with every purple and white)
-In-line fuse, 50 amps or larger
-Some speaker wire
-4 small picket screws
-Basic devices

For the flexibility and ground wires, you will want thicker wires counting on how extremely efficient the amplifier is. REALLY extremely efficient amps might need as so much as a zero gauge wire. Nonetheless I doubt any of you guys will doubtless be using an amp that large.

Step 2: Choosing an amp and speaker

This may very well be a troublesome step. You could choose a speaker and amp that put out in all probability essentially the most power, with out blowing each other.

What you want is the RMS of every the subwoofer speaker and the amplifier to be as shut as potential. The RMS is the amount of power a speaker can repeatedly have despatched to it with out going harmful. The RMS can be the amount of power the amplifier can repeatedly put out with out over heating.

When audio system and amplifiers, do not take a look on the peak power. A speaker or amp can solely be run on the peak power for a few minute sooner than it goes harmful or overheats. You could be working your subwoofers on its RMS rating considerably than the peak rating.

For best sound, protect the impedance (Ohms) the similar too.

Lets take the Kenwood KFC-W3011 as an illustration. Its scores are:
-400w RMS
-1200w Peak
-4 Ohm Impedance

An outstanding amp for this speaker (assuming that’s the one speaker linked to the amp) may very well be the Rockford P400-2. This amp has the following scores when it is in “bridged mode”.
-400w RMS
-4 Ohm Impedance

Choosing a measurement for a speaker can be important. Smaller audio system similar to the eight and 10 inch ones, are very quick to answer and punch increased than bigger ones, nonetheless are normally not very loud. Bigger ones like 15+ inch ones, are very loud compared with smaller ones on the similar wattage, nonetheless have gradual response, and make the sound additional mushy. The bigger ones moreover cope with lower frequencies increased too. 12 inch audio system are compromise for a elementary system.

Make certain you buy a subwoofer area that has a spot the similar measurement as your speaker.

Step three: Run the wires

We’ll start with wiring the flexibility from the battery. You will have to get the flexibility from the battery and by no means the fuse area. Vitality from the fuse area sometimes is “unclean” and it is doable you will hear your engine noise amplified by your audio system. You probably can moreover merely blow a fuse by using the little ones the fuse area has.

Start by discovering a spot inside the car’s firewall. That’s the metal wall beneath the hood of the auto, closest to the windshield. The alternative side of the firewall should be the inside of the auto. I chosen a spot that was behind my glove area and was fairly simple to get to from the engine compartment.

Run almost all the means cable by the opening inside the firewall, guaranteeing to go away adequate wire to get to the battery.

Strip the insulation off of the wire on the end the place the battery is. Wire the in-line fuse to this end (if it is not part of the wire already). You want the fuse as close to the battery as potential. Do not be part of the wire to the battery however. Make certain you tape the place the place you wired the fuse to the wire, so you don’t get a short.

Run the remaining wire beneath the automobiles carpeting or by a wire channel, if there could also be one. You could get this wire to the trunk of the auto.

While you might have the carpeting free, run the 16 – 18 gauge wire and the RCA cables from the trunk to as close to the once more of the stereo head unit as potential, depart a little bit of slack at every ends.

Step four: Wiring the audio

You now should take the stereo head unit out. I can’t inform you the way to try this, because of almost every car producer does it utterly completely different. It usually requires you each take off the doorway of the center console, in any other case you employ a software program to slide the stereo out of explicit clips.

After you’ve got gotten the stereo out, look at the back of it. There should be 2 RCA connections. Run the RCA cables by the once more of the center console and plug them into the 2 connections on the once more of the stereo.

In case your stereo does not have these connections, you will should splice the wires into the rear speaker wires. Greater however, exit and by a model new stereo that has RCA. They aren’t very expensive any additional.

Depart the stereo out for the next step.

Step 5: Distant Wiring

You may must run the 16 – 18 gauge wire by the once more of the center console too. This wire tells the amp that the stereo has turned on, and that the amp should too.

For many who take a look at all the wires coming out of the once more of the top unit, there should be 1 or 2 blue ones. These are generally known as the distant wires. In case your wires are labeled they could be labeled as:
-Distant
-Rem
-Amp
-Amplifier
-Energy Antenna
-Pwr. Ant.
-Antenna
or one factor very like a form of.

If there are 2 wires, there should be one labeled Amp. If there is just one blue wire, you must use that. If in case you might have an affect antenna, you will should splice into the blue wire for use with the amp too. What you will need to do is be part of the 16 – 18 gauge wire to the proper blue wire. When the stereo comes on, so will the amp.

If it is a stock stereo on a car and never utilizing a power antenna and no blue wire, then run the 16 – 18 gauge wire to the fuse area, and be part of it to a fuse that prompts when the tools are on. Your amp will always be on when your car is on, but it surely certainly mustn’t make noise, so its OK. If it does make noise (like from the engine), add a swap so you could flip it on or off.

Step 6: Place the speaker within the field

That’s pretty self explanatory, nonetheless for people who have no idea:

Put the speaker inside the area, guaranteeing the flimsy skinny gasket issue is on it.
If the sphere has its private connectors on the pores and skin, make sure they’re wired to the speaker inside.
Screw the speaker into the sphere, using the holes on the pores and skin rim of the speaker.

Set the subwoofer inside the trunk of the auto.

Step 7: Wiring up the amp

OK now we now have most of the wires in place, we’re in a position to wire up the amp.

Be a part of the flexibility cable from the battery into the spot on the amp that has considered one of many following markings (do not be part of it to the speaker optimistic):
B+
Batt.
Pos.
+12v
12v
Pwr
Vitality

Be a part of the 16 to 18 gauge wire into the spot that claims:
Rem.
Distant
Ant.

Be a part of the three foot, 10 gauge wire to the one marked (do not be part of it to the speaker harmful):
B-
Neg
-12v
Gnd
Flooring

Be a part of the other end of the underside wire to a close-by bolt that connects to the physique of the auto.

Be a part of the speaker wire to the + and – marked for audio system on the amp. There may be 2 channels. If there are 2 channels and you may bridge your amp, do it.

Be a part of the other end of the speaker wire to the + and – on the speaker area. Try and make sure that the + from the amp is linked to the + on the speaker, and the similar with the -.

Step eight: Powering to the battery

The last word step is to go and be part of the flexibility cable to the battery. I merely shove my wire between the battery clip and the publish on the battery.

Be sure that an enormous fuse is inside the fuse holder.

Step 9: LET THE DEEP BASS PLAY
