HOW DO I WIRE MY SUBWOOFERS?

Helpful info from @caraudiofab
HOW DO I WIRE MY SUBS? This has got to be one of the most common questions! If you are asking that after you already have your sub(s) and amp(s) you may have already made a mistake!

For those that may be new (we all were at one point) it is very important to properly match the impedance of the subwoofers to the impedance value you intend to use on your amplifier.

The math for these calculations is rather simple, but I do find that people still have trouble visualizing what the wiring should look like, especially once you start combining both series and parallel, so I wanted to share something cool with you guys from show sponsor Crutchfield that makes understanding the wiring much more simple.

Crutchfield has a tech article that allows you to enter how many subwoofers you intend to use, minimum impedance of your amplifier (which is found in the specs) and see different wiring combinations. To find this article use the clickable link in my bio and search for “Subwoofer wiring diagrams”.

Again, I know for many of us this is the entry level basics, but many newcomers are reaching out asking questions every day and I want to be sure we can help them out too. Today I just uploaded a new video on “Subwoofer Basics”, so be sure to check it out!

In the meantime if you would like to check out more Crutchfield tech articles, and research your next build, along with get a special offer for CAF fans be sure to check out show sponsor Crutchfield here: http://www.crutchfield.com/i-rCAFcIGM/promo/caf.aspx

Thanks for tuning in!

JsAlternators High Output Alternator Installation Instructions

JS Alternators Testimonials

Installation Instructions
MUST FOLLOW ALL INSTALLATION STEPS TO PREVENT VOIDING WARRANTY!

REQUIRED Installation Steps:
(Wear eye protection, remove jewelry/loose items, allow car to fully cool before starting installation)

Batteries must be fully charged before installation.
Make sure vehicle is off and engine is cool.
Disconnect the negative cable from the battery/batteries.
Disconnect all other wiring from the alternator.
Remove the belt (note the belt routing before removing).
Remove the bracket bolts and original alternator.
Mount the new alternator. In general, the original bolts will be used.
Inspect the belt and replace if there are any signs of wear. We suggest you replace the belt with a .5 to 1-inch shorter belt when installing a high output alternator. Install the belt. Make sure routing is correct and the belt is aligned to all pulley grooves.

Connections Of Frame/Body: Clean all metal surface of any paint or rust with a wire brush or die grinder. Use a conductive corrosion inhibitor available at any electrical parts supply store.

Grounding (Uni-body frame warning): Many newer vehicles have “uni-body” or sheet metal frame structures with no traditional “full frame”. Because of seams and adhesive attached body components, additional steps may be required for proper chassis grounding. Choose the location on the sub-frame with the thickest metal possible. If there is lower than spec charging voltage at the battery, move ground connections or add additional ground cables to different frame components.

*** WARNING ***
Keep all electrical wiring at least 12” away from heat sources to avoid fire of the cables jacket!

There are THREE Regulator styles. Read each to determine which one your alternator has and read it’s side-note:

Factory Plug:
Be sure factory plug is clear of all debris and fully snapped into place in regulator.

Turn On Single Wire Alternators:

Follow this step ONLY if we shipped a pigtail plug with your alternator. You need to connect the (L) excite wire to L/IG on factory plug or to a 12volt switched ignition power source and connect sense wire (S) directly to positive post on alternator.

Self Excite Alternators:
Self-exciting or better known as “one wire” alternators will have NO plug on the alternator, and the OEM alternator harness plug will be left disconnected. This type of alternator requires only the positive and negative battery cables to be connected to the alternator to function. These alternators are internally regulated and will turn themselves on and off with engines rotation and regulate their own charging voltage. (May cause battery light to cut on).

Gauges
It is highly recommended you add a dash mounted volt gauge.

Connect the battery ground and confirm all other electrical connections are complete.
Confirm the belt path is correct and clear of obstacles.
Before starting the vehicle, check and confirm that the battery is charged.
Starting the vehicle with a discharged battery can damage the alternator.
Use a battery charger to charge the battery first if voltages are not adequate.

Ground Path Resistance Test
If resistance is greater than 0.1V confirm the following:
Confirm all paint, anodizing, rust removed, and the connections are to bare metal.
Make certain all terminals are tight to the wire.
Make certain the ground wire is of proper size.

Charge Path Resistance Test
If resistance is greater than 0.1V confirm the following:
Alternator charge post nut is tight.
Make sure charge wire is proper size.
Battery Recommendation

2000 watts: upgrade main battery, 1 rear battery
3500 watts: upgrade main battery, 1-2 rear batteries
5000 watts: upgrade main battery, 2-3 rear batteries
7500 watts: upgrade main battery, 3-4 rear batteries – 2 alternators
10,000 watts: upgrade main battery, 3-5 rear batteries – 2 alternators

How Does A High Output Alternator Work?

A vehicle comes with a stock alternator from the factory to meet the basic electrical needs of a vehicle. A high output alternator or high amp alternator is a perfect way to upgrade modern vehicles. A modern vehicle is different from traditional vehicle since it can require higher electrical supply for, power windows, modern seats with heating and cooling systems, power gates, ignition systems, compressors, navigation systems and more. A high output alternator provides higher amperage output to a vehicle, improving their performance. This article discusses the different types of high output alternators, their functions, how they work and how to prevent them from going bad. To find out more about high output alternators please read below:

Dodge, Chrysler, Jeep PCM High Output Alternator Charging Explained

The Chrysler charging system is slightly different from the other systems. Chrysler has used three different charging system designs over the past few years: local interconnect network (LIN), analog controls (used only with 1.4L engines), and their most popular system, which is PCM controlled.

Most Chrysler alternators don’t typically contain a regulator, the exception being the analog-controlled application. Chrysler controls the alternator externally. A PCM controls the field current. The voltage regulator electronics are housed within the PCM.

The PCM will typically receive a battery voltage input on two circuits: one from the alternator B+ sense circuit (Kelvin sense) and one from the totally integrated power module (TIPM).

Chrysler may control one or both sides of the field (power and ground). The field current flow will vary based on electrical demand, battery state of charge, and engine RPM.

Honda ELD Dual Mode High Output Alternator Charging System Explained

Honda uses a dual-mode charging system on most 1990-2012 applications (figure 3). This system decreases drag on the engine while cranking and reduces charging system output (engine load) for improved fuel economy. Similar to other systems, the PCM controls the alternator. The PCM receives the system voltage and amperage demand from the electronic load detector in the fusebox.

Cranking (Low Output Mode) — during cranking, the PCM will set the output target between 12.4-12.9 volts. This mode will be active when the system meets a given set of criteria, leading the PCM to command the alternator to reduce the charging system output. Don’t misinterpret low output mode as a bad alternator.

Normal Mode — with the engine running and a specific set of criteria met, the PCM will command a target output voltage between 13.5 and 14.9 volts. With the ignition switch on, the alternator should receive a signal on the IG circuit greater than 12 volts, which it uses to activate the alternator.

Ford Smart Charge High Output Alternators Explained

Ford Smart Charge was introduced on the 1999 Windstar. Like the GM system, the regulator is mounted in the alternator. The PCM then controls the regulator to control system output. It’s similar to the operation of the GM system, with two main control connections to the alternator: generator monitor (GEN MON) and generator command (GEN COM). GEN MON and GEN COM are similar to terminals F and L on a GM system (figure 2).

GEN COM — Generator command controls the system output. The PCM sends a 128 HZ PWM signal to the alternator GEN COM terminal. The duty cycle varies from 3% to 95% with the high duty cycle corresponding to higher alternator output.

If the battery voltage is correct, there won’t be a signal on the GEN COM circuit. If an open circuit occurs, the output voltage default will be 13.5- 13.7 volts after engine speed exceeds 2500 RPM the first time.
