Setting Up the Best Car Sound System

The first head unit I ever bought to upgrade my sound system was a Pioneer DEH-1600, with just a radio tuner and CD player. At the time I was low on cash, and looking for only one thing: bass. I hooked that up to a pair of 12” 400W Rockford Fosgate subwoofers with a no-name brand 500W amp, and thumped around town without thinking much about RMS power ratings, channels or ohms.

Things have changed quite a bit since then, and there are more options than ever for today’s audio-conscious motorists. It can be overwhelming when comparing components and sizing up features. I am going to break up the components of a sound system and, hopefully, make it easier for you to figure out what specs matter most for your application.

Sound Systems Levels

The way I see it, there are generally three levels of sound systems:

• Basic: This is simply for people looking to gain more power and options than their stock system without breaking the bank. This could be a simple add-on to the stock system or a basic component upgrade across the board.

• Mid-range: These systems offer more features and power for a customized media experience. However the cost is also greater. These commonly consist of all-around component upgrades.

• Advanced: Systems in this category are fine-tuned and very well-rounded for people looking to get as much as possible from their audio/visual experience. The features available can be almost unreal, and result in awesome ground-pounding performance.

The Head Unit:

The main component of any sound system is the head unit (HU). It is where all your sound originates, and where most of your sound adjustments are made. There are several factors to consider when comparing HUs, such as:

• Source: This is where your media comes from be it AM/FM, CD, iPod/AUX, USB, DVD, satellite radio, navigation, app-compatibility or Bluetooth. A basic HU may just have AM/FM and CD, while a mid-range unit may have AM/FM, CD, iPod/AUX, and an advanced unit can have all of the above.
• Preamp: This is the sound adjustment center. Typical features are balance, fade and equalizer. More advanced units can also have crossovers networks.
• Power: The RMS power is what your unit will consistently produce, while the max power is the maximum your unit can produce. It is good to have a higher RMS rating so you can have more room to operate before you max out your equipment.
• Other Features: Some units have touchscreen monitors, color-changing displays or other little perks manufacturers offer for aesthetics.

My recommendation: Basic HU, Mid-range HU, Advanced HU

Amplifier:

If you are doing a basic swap out for a new HU or even mild speaker upgrades, you may not need an amplifier. If you are looking to use more power with high-range speakers or subwoofers, you will definitely need an amplifier. Amplifiers give you more power and also better sound quality. Some key features when choosing an amp are:

• RMS rating: As mentioned before, this is important to know so you can have a realistic expectation of how your system will perform. For a basic setup or smaller vehicle interior, 50W RMS per channel is usually sufficient, while upping to 75W & 100W RMS per channel or more is better for mid-range or advanced setups.
• Channels: The number of channels is essentially how many different devices can be powered from the amp. A 4-channel amp has room for 4 devices while more advanced units have 6 or 8 channels. You can set up your system with various configurations depending on how many speakers you want to install.
• Ohms: This is a measure of resistance, and amps are commonly designed to work with 4, 8 or 16 ohms of resistance. To get the maximum performance from your equipment and prevent any damage, you should match the total ohm load of the speakers to the amp. If the total speaker impedance is too high, the power delivered to your speakers will be reduced. Too low and the power delivered will be too high and could damage both your speakers and amp. A simple trick is to take the ohm rating for the speakers and divide by the number of speakers you are hooking up. This will give you the overall ohm rating.
• Class: There are several classes of amps, designated by their circuit design and power stage output. For all practical purposes here, Class D amps are the best route to go. They use output transistors as switches to control power distribution, while staying cooler than other classes. These are efficient, light, compact and produce great quality sound for any setup level.

Taking into account how many speakers you will hook up and what the power requirements your speakers need, can give you a good estimate of the power you will want from your amp. It is best to choose an amp with good headroom between the RMS and the peak power.

My recommendation: Basic amp, Mid-range amp, Advanced amp

Speakers:

• Driver use: Speakers are either full-range or component, which is differentiated by their drivers. The driver converts the electrical frequencies to sound inside the speaker. Full-range speakers have only one driver, which means all frequencies originate in the same location. This is more common and cheaper for basic systems. However it may not produce the best sound. Component systems have one driver per speaker, which allows for different sounds to be originating from different speaker locations and provides the richest audio experience. These are also more expensive, so a mid-range or advanced setup will likely have these.
• Type: There are different speakers depending on which tone you might be looking to improve. Subwoofers are on the low end of the spectrum and all about the bass, while the super tweeters are at the opposite end and handle the highest-pitched sounds. The speaker types you choose should depend on your preference, and how deep you go into the upgrade.
• Size: Will your speakers fit into the factory locations, or will you make custom enclosures?
• Power: Remember, matching the power capabilities of your amp and speakers properly will ensure clear, consistent sound.

My recommendation: Basic speakers, Mid-range speakers, Advanced speakers

Upgrading Your System

With any auto upgrade there are always many choices, especially when dealing with audio. The most important part you need to figure out is what you are looking for in a system to give you the most enjoyment in your listening experience. Then build it.

What kind of sound system do you have in your car?

    What do you recommend for a sub amp? And sub speakers?

    Great article. I would suggest an addendum on basics of *wiring* a car stereo including RCAs, Power and Grounding cables, proper fusing, safe routing from engine to amp with additional fusing within 1ft of the battery, making sure that alternator output is appropriate for the amperage draw from the amp, basics of why you might choose to install a capacitor and things of that sort.

    With over 34 years of installing retail and sales. I can assure you, you only have a basic idea of mobile audio. In fact some of you information can be misleading. Ive never seen a car amp for a 16 ohm load. Here is one point you did not make, impedance loads also determain how clean something will play. Take RMS ratings in car audio with a grain of salt, there not fact. There are no government rules on rating car audio equipment. But a key to it is look at the fuse if you have a 400 watt amp but its power fuse is 10amps its not a 400 watt amp it can’t be because according to ohms law it can’t make that much power. Also if a speaker says 350 watts its not putting out anything until you hook it up to a amp or power scores. Buying online might make you think you saved money, but if you truly don’t know what your doing your just wasting money. Pay a pro you’ll be way better off. Also now there is almost no profit in car audio, if your paying more its overhead and or it actually comes with some warranty and its not gry market goods. With new cars even pros have problems installing mobile audio, and cars are extremely complex today. One mistake and you could be out 1000 of dollars to correct it. Most pro installers have had some type of training and experience. They are worth what your paying.

      Dude you are spot on.. Cheaper and better results getting a pro to design and install your system.

      I’ve seen way too many hack jobs, guys cutting out parts of the body, electrical wiring ripped out, running wires where they shouldn’t be run…. These systems are not plug and play like a typical computer components, if you don’t know what you’re doing, you’ll spend thousands of dollars for a system that sounds worse than stock!! Then I’ll charge twice as much to fix it!!
