Ever find yourself asking ‘how much does it cost to install a subwoofer and amp in a car’?

• Head Unit: A new Head Unit can cost as much as $100 to connect, although many vendors include installation costs in the purchase price.

My favorite place to listen to music is in my car. Partly, it’s because I find a sense of serenity while I drive, allowing me to relax and appreciate it more. Secondly, it’s because I have had an awesome sound system installed in my car.

Achieving perfect car audio is a big job, which can seem particularly daunting as you begin to price your options. I shopped around extensively to make sure I found the best deals out there, that – most importantly – didn’t detract from the quality of the finished product.

We will cover every step of the process, as well as every cost you are likely to run into along the way:

• Determining whether you will be able to wire it yourself.
• How to determine the cost of fitting a head unit, amplifier, and speakers.
• How much the whole process is likely to cost from some of the most reputable firms.

Determining Sub And Amp Installation Cost

The cost to connect your car stereo varies exponentially. If you were to simply purchase and install a new receiver or CD Player for your car, that could easily be done for under $100.

But when you begin to explore options for having a more expansive stereo system installed, things get a bit more pricey. Here are some common components of car stereo systems, and how much they tend to cost to have installed:

Head Unit

Replacing your car stereo with a new head unit could be an area where you save a bit of cash. Many reputable firms offer “free installation” services: if you purchase your new receiver from them, they will install it for you free of charge.

If not, you are likely to find a head unit installation service for between $50 and $150, based on make, model, and labor hours.

Car Amplifier

A good quality amplifier is essential for any car stereo system that is looking to add subwoofers and other powerful speakers into the mix. Without it, your car’s battery will struggle to supply all the components with enough power to function properly.

But deciding to have a car amplifier installed is indicative of a project becoming significantly more expensive. One can expect to pay between $120 and $130 to have their car amplifier installed, excluding vehicle-specific parts and labor.


The cost to install speakers varies significantly, largely on account of the process required to make it happen.

A subwoofer could be hooked up for as little as $20, but more extensive jobs – like fitting speakers that require car doors to be removed – can end up costing as much as $300.
In modern cars, you could be looking at replacing up to eight speakers, which may quickly add up.

Installing A Sub And Sound System In Your Car Yourself

Installing a subwoofer and amp in your car is a no-brainer. Bass is the most difficult range of the sound spectrum for speakers to produce, so your factory car audio system will often struggle to reproduce the low tones in the music you play.

This is even more important to note if you have your sound at loud volumes, where the distortion alone can be enough to ruin even your favorite songs.

So, as soon as you have decided to invest in a subwoofer and amp for your car stereo system, you will soon be faced with an important choice: do I wire it myself, or pay a reputable firm to do it for me?

You may be inspired to purchase all the necessary components and get on with it yourself, but there are a few complications that can arise if you lack the confidence and experience:

• It is easy to damage your car’s electrical system during the installation process, particularly if haven’t much experience with it.

• Wiring a complex car stereo system is a much bigger task than fitting a new radio. A professional may be better equipped to ensure your car battery is wired such that it has the current to spare to power a receiver, amp, and speakers.

• Incorrectly wiring, leaving live wires hanging, or exasperating battery issues are all common causes of electrical fires that can end up deadly.

For this reason, many turn to reputable firms to hook up their advanced car stereo systems for them.
