Trim panel removal tool Step 1: Installing the 12v Power Wire In your amplifier wiring kit, generally a red in color wire is the longest one, which is the 12v power wire. You need to pass the wire through the firewall. Start from the battery and pass on to the amplifier. However, do not connect the wire to the amplifier or battery yet. Removing the Stock Stereo Remove the stock car radio from the dashboard of your car. Make sure that you carefully remove the screws that hold the stereo in place ensuring that no wires are cut. Installing the Remote Wire Once you remove the stock stereo, you will see a blue and white wire, which is basically your remote wire. This wire is located at the back of the stereo deck. Get the remote wire in your wiring kit.
How to Connect a Powered Subwoofer
And back at installing more electronics into my car. No subs this time, and no 3 or 4 amps. So, I searched and searched for an answer to this question in the forums but couldn’t locate anything, so I figured I’d run it by you all in a new topic. My question where I need opinions or advice this time has to do with powering tweeters.
Jan 12, · If your amp can only handle an 8 ohm impedance, you can take 2 4 ohm subwoofers, connect them together in a series circuit, then you will have 8 ohm impedance. The best subs to use are car subs, bar none.
Last updated 13 November, 26 Very different to the type of amplifier you may have in your home stereo, PA power amplifiers are designed to run at high levels for long periods of time. In the first part of this four-part series we looked at the basic elements you need to know about when it comes to DJ PA systems. In the second part , we carried on laying the groundwork by answering some common newbie questions.
It is vital that the amplifier can supply sufficient power for your speakers say W , but your speakers also need to be able to handle this amount of power. So if you have the amplifier with W but your speakers are only made for W, they will die on you rather soon. So I always recommend to shop for amplifier and speakers together. Alternatively, you could go for active speakers. These have the power amplifier built in and the manufacturer has already done the job of matching the amplifier s to the speaker s , so you no longer need to worry about it.
Now, a PA amplifier is very different from a hi-fi amplifier.
How to hook up a subwoofer to a stereo system
This is only for general information. Be sure to weigh your need for an aftermarket stereo compared to voiding any warranties. If you are unsure about what you are doing, Please find someone who does. I would hate to see a radio burn out because of crossed wires during installation.
Feb 02, · If you have A and B speaker outputs from the receiver, you can hook the sub to the B terminals. This doesn’t create demand on the receiver, it just strips the signal off, so it should work fine.
JL f subwoofer backpanel ; Right Pic: This is the dedicated subwoofer output of the receiver that sends LFE info from discrete 5. There are several reasons for this: This is especially true if the crossover frequency of both the sub’s LPF and your receiver’s bass management are set to the same frequency.
This is called cascading crossovers and should usually be avoided. We recommend setting the phase switch to 0 degrees or positive.
The OC dspargo said: The receiver has the ability to run both A and B speakers at the same time. The receiver manual says all the speakers 3 in this case will be run in a series. It will be better in that there will be less resistance in the wire between the amp and the speakers. If you run the speakers through the sub you will use more wire.
Head Unit Has No Remote Wire A relatively common problem is installing an amplifier with a factory head unit or other head unit without a remote turn on wire (or a burned out circuit). So the amplifier doesn’t stay on 24 hours a day you need a way to turn it on and off remotely.
Head Unit Has No Remote Wire A relatively common problem is installing an amplifier with a factory head unit or other head unit without a remote turn on wire or a burned out circuit. So the amplifier doesn’t stay on 24 hours a day you need a way to turn it on and off remotely. Hence the term “remote turn on wire”. Almost every aftermarket head unit has a remote turn on wire. Some manufacturers call it a power antenna wire. But regardless of the label all it does is output a positive 12 volts when the head unit is turned on.
It should be noted that some head units have both a remote turn on wire and a power antenna wire. It’s important to use the right wire for your amplifier and other electronic equipment. In the case of both remote and antenna wires the power antenna wire will only output 12 volts when the radio is on. If you were to connect your amplifier’s remote terminal to the power antenna wire then you would only get output from the amplifier with the radio.
How to hook up an amp to car speakers?
Tweet Expand the power of your current setup without breaking the bank More and more people are recognizing the benefits of a powered subwoofer , and not just DJs or techno musicians who need to pound out an earth-shaking beat. You can buy a three-speaker system that includes a subwoofer or will accommodate one when the time comes to upgrade , but anyone can use a subwoofer in any system at any time.
The trick is in the mixer and the output it has called an aux send or aux bus. For bands that have been getting along with their current PA and are starting to play larger venues, or just realizing they need to kick up the output a notch, investing in a subwoofer will often supply the additional power you need at an economical price. Take the sub way Here are some of the advantages of bringing a subwoofer into your system:
If you’re fitting subwoofer speakers in a box, mounting the amplifier on the side of the box is a good option. Mount them up high to avoid damage and maximize airflow.
Dont even think about running this big wire through the door jamb, run it through an existing gromit in the firewall and fuse the wire amp within 12 inches of the battery. Disconnect the negative battery wire before you do anything. Ground the amp to solid frame seatbelt or seat bolts and large ring connectors work well , if you dont, it will ground through the rca cables and make large amounts of smoke when you turn it on.
Depends on the impedance of each speaker. If they are car subs and not converted home speakers, they are probably 4 Ohms each. Depending on how you wire them you get either 8 Ohms or 2 Ohms.

So what will we need to do this? But I doubt any of you guys will be using an amp that big. Walmart sells amplifier kits as do some other stores. The kits tell you how many watts they can handle.
Subwoofers need lots of power so typically you will bridge the power from two channels into one to power the sub. Most often you accomplish this by connecting the positive wire from the subwoofer to the positive lead of one channel on the amp and then connecting the negative wire to .
All it takes is a little know-how and a few tools and supplies. Go to your local car stereo shop and get an amplifier wiring kit. It should have everything you need from cables, wires, fuse and connectors. You need to figure out where you want to put the amplifier. It needs ventilation so most people put it in the trunk or under a seat. Open the hood and disconnect the negative battery terminal.
