The vehicle’s mounting location will determine whether you’ll go for full range speakers (also referred to as coaxial speakers) or 6x9 or 6.5 units. Usually, 6.5-inch units are preferred for rear deck speakers while front car door speakers are best suited with 6x9 inch units. The most difficult process is usually finding the best balance between clarity, performance, sharpness and the sound depth of the speaker.

Component speakers are separate crossovers and tweeters that produces an outstanding sound imaging and adds more realism to your music. These speakers can make a big difference when it comes to the quality of sound emitted by your system. It is usually recommended that you move full range speaker units from the first step to the car’s rear deck and then fix the component twitters and crossovers up- front. It is important to note that installing component speakers involves a more complex process than their full-range counterparts.

Stage 5: Select a Multiple Channel Amplifier

You’ll need an external multiple channel amplifier that gives you the freedom of adding a new components as you go. Multiple channels are more flexible compared to the factory units. Amplifiers are like boosters since even aftermarket head units (receivers) are not usually not powerful enough to drive the entire audio system. Amplifiers come in various channel variations but the more the number of channels the better. You can prefer to use two of the channels to power the front-mounted speakers and bridge the other two channels’ output for powering a subwoofer. Five channels amps are the most reliable as they allows you to power the whole of the sound system, subwoofer included. Four channels are usually used for powering the front and rear speakers while the fifth channel is purposely for powering an external subwoofer.

Step 6: Select a Sub-woofer

After selecting an amplifier, now drop a subwoofer into the mix. This gives you an opportunity to enjoy that bass that you’ve been missing. If you selected a 4-Channel amp in the previous step, then you’ll require another single channel amp for driving your sub-woofers. If you opted for the 5-channel amp then you’re better off because you’ll use the fifth extra channel for driving the subwoofers. However, for more professional and robust installation, it is recommended that you go for a separate mono channel amp for powering the subs. There are different sub-woofers available in the market.

When buying a sub-woofers, always consider the following factors:

  • Frequency Range
  • RMS Power handling
  • Size
  • Type
  • Sensitivity
  • Rating
  • Impedance
  • Load

Step 7: Build a Better Sub Box or Simply Buy One

You should never install a subwoofer inside a wrong enclosure as this will affect its performance. It is recommended that you built your own box with the correct dimensions or just go for an enclosure in the market. Don’t destroy your ported box subwoofer by forcing it in a sealed enclosure.
