Can you hook up an amp and subs to a stock stereo?
Adding a subwoofer to a factory stereo is an excellent method to boost your sound while retaining your factory controls. The nifty devices can produce bass and sub-bass sounds at low frequencies. Thankfully, it's pretty simple to wire one into an existing car stereo system.
Is it OK to bridge a amp?
You could get a small 2-channel amp that normally puts out two channels of 60 watts RMS, and bridge it, so it could produce an output of 190 watts RMS, which would be perfect for driving the sub. Please note: Most amplifiers, when bridged, cannot drive a speaker or sub with an impedance less than 4 ohms.

Whenever there's one available, we recommend bypassing the factory amp to get better sound. If you're considering a new stereo for your vehicle, keep this option in mind.
Can I add an amp to my factory stereo?
Usually, you'll be installing a 4-channel amplifier with speaker-level inputs. The best way to connect it to a factory system is to tap into the stereo's speaker outputs for the amp's input signal. Then send the amp's outputs back to the stereo's harness, and on to the speakers through the factory wiring.
Is Bridging subs better?
"one 2-ohm sub on each channel, or two 2-ohm subs in series on a bridged amp, the power output is the same. it won't matter which way you wire it. It would be slightly better to bridge even though the power is not increased.
Does bridging an amp affect sound quality?
It will slightly degrade the measurements (THD, damping, power bandwidth, etc) but not so much that it is a sure fire thing that you will hear a difference. If your center channel speaker is rated at 4 ohms, then that could cause a problem if your amp wasn't rated as stable into 2 ohms when in stereo mode.
Does bridging amp lower ohms?
When you bridge an amp the ohm rating does not change. You can only change the ohms by wiring speakers differently(series or parallel).
What is bypass on subwoofer?
Some brands of subwoofers may have a "Bypass" switch, which does the same thing. By doing this, you are avoiding "cascading crossovers," or using two crossovers in a row, which may cause losses or gaps in the bass response.

What Is Car Amp Bridging?
Bridging allows you to get the most power from your car amplifiers by using a built-in channel-sharing design. In car audio applications, bridging is often used to provide more power to sub-woofers or larger full-range speakers.
How To Bridge Subwoofers – Connecting to a Bridgeable Amplifier
Find the specification labels for your system. An amp label should be placed near the speaker output jack. It should indicate the amp’s output power (measured as Watts) along with the minimum impedance, measured in Ohms.
FAQs
A bridged amplifier refers to the combining two of four amplifier channels into one or two-channel amp with half the ohms. The technique has become very popular among many car owners because it allows amplifiers to send out more power for the mono signal to the subwoofer or speakers.
What is bridging an amp
The term “bridging” refers to the process of combining and/or consolidating a pair of channels in an amplifier. This reduces the resistance load or impedance of the amp (measured in Ohms ).
What does bridging an amp do
When you bridge an amplifier, you combine a pair of channels into one channel configuration with half the resistance load (Ohms). This means you can pump almost twice as many watts to your speaker.
How does an amp make more power when bridged?
In technical terms, this increase in power has everything to do with Ohms. With a bridged amp, you’re using lower impedance to drive higher impedance, maximizing your voltage transfer.
Before you begin
There are a few things you should know before you bridge. This is because there are both benefits and drawbacks to bridging, as well as the risk of damaging your amplifier if done improperly.
How do you bridge an amp
Now that you’ve double checked your amplifier, let’s get into the actual process of bridging your amplifier. Most commonly, people bridge a 2 channel amplifier for a subwoofer, so that’s the example we’re going to use here.
Can you bridge a 4 channel amp
While the tutorial and diagram above is for 2 channel amps, it’s possible to bridge a 4 channel amplifier, too. I’ll tell you quickly how to bridge a 4 channel amp. The process is essentially the same as it is for a 2 channel amp.
How do you find your minimum speaker load (Ohms)?
Figuring out your minimum speaker load in Ohms is very important when approaching the task of bridging an amp. Sometimes this is stated in an easy to find place either on the amplifier itself or in the included documentation.
How to connect an amplifier to a speaker?
Connect the amplifier to one speaker. From the wires coming out of the speaker, connect the positive speaker lead to terminal A (the positive for channel 1) and connect the negative speaker lead to terminal D (the negative for channel 2).
How many terminals are there in a two channel amp?
On your two-channel amp, you should see 4 terminals: a positive (+) and a negative (-) for channel 1, and a positive (+) and a negative (-) for channel 2. Each terminal will be labeled as follows: Connect the amplifier to one speaker.

Make sure your amplifier can be bridged. This should be indicated on the documentation pamphlets that came with the amplifier, or the amplifier itself. If the amplifier is used, or lacks documentation, go online and check for the specifications on the manufacturer's website.
What is the label on an amp?
Your amp should have a label near the speaker output jack that indicates the output power (measured in Watts) and the minimum impedance (measured in Ohms). Be sure that your use the values for bridged mode, it is usually double the minimum impedance as stereo mode (meaning you need a much high impedance to run a bridged system) ...
How many ohms does an amp need?
You want the impedance to be at least equal to the minimum impedance value of your amp on each channel, but not to exceed 16 Ohms unless your amp is specifically rated for impedance values above 16 Ohms.
How many inputs does a DVC sub have?
The difference to remember is that dual voice coil (DVC) subs have two coils, and thus four input terminals. Two of them are positive and two are negative.
