General Car Audio Info

       We know that everyone has different levels of knowledge when it comes to car audio. This page was created to make sure everyone has this general car audio info to get started with.

       When considering purchasing just about anything for your car/truck/van or SUV please make a point of ALWAYS measuring first to make sure it will fit. Then once it looks to fit, please measure a second time to be sure. This will save you a tremendous amount of time, money and frustration by avoiding getting the wrong products.

 


  • Car Stereos:

Please consult the manufacturer of your vehicle or the owners manual to determine the correct DIN.

  • Single DIN: Single DIN fits in dashes that require a small car stereo.
  • Double DIN: Double DIN fits in dashes that have space for much larger car stereos.

  • Speaker components:
    • Woofer: The largest speaker. This is used for deeper bass tone.
    • Tweeter: The smallest speaker. This is used for making everything sound clear instead of muddy.
    • Mid-range: Not all speakers have this, however if they do they typically sound better than most other speakers. These reproduce a wide range of sound not found in most speakers.
    • Bass Port: Not all speaker cabinets have these. Of the ones that do include these they are located in either the front or back of the cabinet and help push the bass out of the speaker to reduce distortion (vibration of the speaker).

  • Subwoofer (Sub): a speaker or group of speakers dedicated to reproducing really low frequencies for much deeper bass that you can feel.

  • Amplifier (Amp): All car stereos come with their own built in amplifier. Some car stereos allow for a pre-amp or amp to be connected to it as well. The amp will produce clean sound for crisper highs and deeper lows. This is especially useful when using much larger speakers (typically in a speaker box such as 8’s, 10’s and 12″ woofers.

  • 2 Way Speakers: These speakers only contain a tweeter and woofer.
  • 3 Way Speakers: These speakers contain a tweeter, woofer and mid-range.

  •  Frequency Response: The human ear can hear from 20 hz to 20,000 hz (also referred to as 20 khz). The wider the frequency range that the speaker can produce, the more you will hear.

  • Ohms: Anywhere from 2 ohms to 8 ohms depending on the speaker. With car audio, typically it will be either 2 or 4 ohms. The lower the number the more efficient it will be and therefore require less power to push the speakers to perform.

  • Watts/Wattage: 

Not all speakers will indicate if it is the RMS or Max power rating being listed. As a safe rule of thumb figure on dividing the number in half and using that number as the RMS.

  • RMS: This is the level at which the speaker(s) can withstand all day long.
  • Max/Peak Power: This is the level that the speaker(s) can handle for a brief moment.

  • Sensitivity: This is measured in decibels (DB). The higher the number the louder the speaker will appear. Most speakers are around 89 db to 92 db.

  • Speaker Cabinet (box): This is a wooden box that is carpeted on the outside for better acoustics. This is used to attach speakers to. Typically these are used for large speakers (8″ and up).
