The three factory holes and the machine screws can be used to fasten the subwoofer down after it has been slid into position. Cut the stock harness off and splice it to a section of speaker wire that wires into the subwoofer to wire the new sub. The speaker grills, tweeter speaker cables, and deck cover should all be reinstalled.

Can a factory radio be connected to a subwoofer?
1) The stereo system cannot be replaced since it is a new model (or an expensive exotic model), or…
2) You simply prefer the factory look and don’t want to replace the stereo.
Rca jacks are plugged into these red and white inputs found behind stereos to create sound.
Will you have to put up with the OEM system’s transistor radio sound?
Here are two methods for adding an amplifier and subwoofer to your factory-installed system:
Hi-Low Converter
For decades, this has been the tried-and-true technique for adding bass systems to OEM stereos.
It’s basically a tiny converter with RCA inputs that connects to your speaker wires.
Your subwoofers won’t produce the same audio quality as an aftermarket radio (such as an Alpine or Kenwood) would in your vehicle.
The stereo isn’t getting the right amount of “juice” because you aren’t increasing its voltage.
A line out converter
In computer-speak:
It transforms speaker level signals into high-quality preamp signals that may be fed into an amplifier by taking the amplified speaker level signals.
For us, it simply means that you’ll receive fantastic sound while retaining your stock stereo and controls.
One excellent illustration of a high-end line out converter is the JL Audio LOC-22:
Even if your car already has a high-end factory system and you still want more bass, this little guy can help.
Without sacrificing the authenticity of the factory system, it converts the high-level signals from your factory amplifier to the line level that your amplifier requires.
Sincere to say, we hardly ever suggest hi-low converters unless the customer is operating on a tight budget.
Funny thing is, hi-low converters usually cost $20, yet the LOC-22 only costs $79! Not a significant difference.
You now know that adding a subwoofer and amplifier to your OEM system will undoubtedly make it sound better.

How can I upgrade the OEM stereo with a subwoofer?
The procedures for adding a subwoofer to a stock stereo are very simple to follow. There’s no reason to worry. If you just follow along, you ought to be fine.
Step 02 :Choose a speaker and an amp
Before burning out or overheating, a speaker or amplifier can only operate at maximum capacity for roughly a minute. Instead of focusing on the peak rating, you should think about the RMS rating of your subwoofers.
Step 03 :Remove the battery from the vehicle
The most significant task you will complete is this. If you overlook this problem, nothing will operate as it should. This is ultimately about safeguarding you.
Step 04 :Disconnect the wires of the speaker
Simply unhook the wires from their corresponding ports or terminals, turn off your vehicle’s main power supply, and reconnect them later.
Step 05 :Identify the relevant connections
Look for any connections that might be crucial to this connection process after creating all of the output ports. Connect the output port on the subwoofer’s box to the LFE jack on the receiver. Utilizing the provided hole, just attach the jack to the port.
Step 06 :Run wires
Connect the battery first. Find a crack in the firewall of the car. While leaving enough cable to reach the battery, run the majority of the power wire through the firewall hole. Remove the insulation from the wire’s end, which is where the battery is attached.
The in-line fuse should now be connected to this terminal. Run the leftover wire via a wire channel, if present, or underneath the carpeting of the automobile. Get this wire to the trunk as soon as possible.
Step 07 :Reinforce the connections
The next step is to tighten the connections by joining the subwoofer’s positive wires to the (+)-designated left speaker. The left speaker bearing the symbol should be connected to the negative wires whose source is the sub box (-).
Step 08: Connect the speaker cable and plug in the battery power.
The Subwoofer should now be carefully connected with a speaker cable. The signal from your stock stereo should now be present. Reconnect the power cable that was previously severed.
Bang & Olufsen 3D Sound System
By producing a very realistic three-dimensional sound impression, the Bang & Olufsen 3D Sound System for the Audi A4 pushes the benchmark for audio excellence in the automobile industry even further. A total of 19 speakers are included in the system, each of which is contained within a grille that is flawlessly incorporated into the Audi A4’s interior appearance.
The 16 channel Class D amplifier produces 5.1 surround sound with 755 watts of clarity and crispness. Together with Fraunhofer Symphoria technology, the audio system gives the Audi A4 a sense of acoustic spaciousness that also raises the bar for 3D sound reproduction in automobiles. The Vehicle Noise Compensation (VNC) technology integrated into the amplifier ensures audio constancy is maintained regardless of what is going on outside the cabin by automatically changing timbre and loudness depending on information from a number of internal and external on-board sensors and microphones.
Excellent styling and acoustic transparancy
Excellent aesthetics and unmatched acoustic transparency are combined by the Bang & Olufsen Dynamic Lines Design feature. The speaker grilles match the interior’s style and have LED illumination, anodized metal accents and logos, and visibility from both inside and outside the car.
Additionally, the system makes sure that respect for individual preferences is always remembered: The volume levels in each passenger’s space can be changed using a variety of parameters.
How many speakers are there in the Audi A4 from 2009?
Our 2009 Audi A4 Avant’s Concert sound system has 10 speakers and 180 watts of power. The speakers are amplified by three 20-watt and three 40-watt channels totaling six.
Can my automobile merely have a subwoofer added?
Thanks to straightforward aftermarket subwoofer modifications that can be fitted to practically any pre-existing car entertainment system, it’s actually fairly simple. You typically need to buy and install an amplifier in addition to the subwoofer in order to power it.
Do I need an amp to install a subwoofer in my car?
The answer is yes almost always. You’ll need to locate an amplifier that will power your sub unless your vehicle or boat already has a system that does so. A low-power signal (RCA output) from your head unit is often available for use with an amplifier to drive your subwoofer. However, without the amplifier, your system essentially operates at 2 or 4 volts (sometimes higher), which is insufficient to drive a subwoofer. Subwoofers consume a significant amount of power and, depending on their size, may even need a separate amplifier.

Should I upgrade my stereo with a subwoofer?
You’re probably in good condition if your home audio system includes a pair of huge tower speakers (although you could still add a subwoofer for extra bass oomph). But bookshelf speakers are much, much smaller. Because of this, they are much more practical. Smaller speakers, however, face a harsh reality when it comes to producing low frequencies. Bass is made up of low frequency sound waves, and in order to produce those low frequency waves, you need a big driver that can move a lot of air.
Large drivers with an usual diameter of 8 inches, 10 inches, or 12 inches are the foundation of subwoofer construction. Of contrast, the woofer, or driver, in most bookshelf speakers may range in size from 4 to 6 inches and is responsible for low and mid-frequency sound. That woofer is working hard to cover the low end and the mid range with many bookshelf speakers’ dual driver arrangement.
Your audio system now includes a speaker that is specifically designed to produce low frequency sound, and it is outfitted with a large driver that can produce those ultra lows, thanks to the addition of a subwoofer.
This increases the realism of effects like explosions and revving motors in a home theater system. It adds subsonic rumbling and depth. The subwoofer in a home audio system gives bass guitars and drums more prominence and depth. Even if a small stereo listening system with competent bookshelf speakers can provide passable bass, adding a subwoofer can make all the difference in the world.
What is the price of installing a sound system in your car?
Depending on the system you select, you might pay as little as $400 to $500 at Car Stereo City for a comprehensive car audio system package that includes our professional installation services.
