How to Select Car Audio Speakers

Installing a new set of car audio speakers should be a very simple upgrade for any car sound system. In most cases it will be a simple job of matching the size, power and resistance (OHMS) of your OEM speakers. Just don't fall into the trap of attempting to increase the size of your speakers expecting better quality and louder sound. This is a common error which simply isn't the best way to go.

The first point to consider is the suggested power requirements of whatever speakers you might desire. The best way to compare car audio speakers is to compare the continuous power or RMS of the speakers. You will have to check your vehicles sound system to determine if there is an amplifier or just the source unit powering your speakers. Most OEM premium sound systems have an amplifier incorporated in their setup.

You might want to consult your car dealer or a local custom shop to check on this.
Most entry level speakers from the better brands will perform perfectly just being driven by the source unit. But if you are going to invest in high quality car audio speakers, you should really consider installing a power amplifier. No matter which way you decide to go, you will find that just about any aftermarket car audio speaker will out perform OEM installed speakers.

The next thing to consider is finding the correct size speakers for your specific vehicle. There is only one way to ensure you purchase the correct size and that is to pop-off the door panel and actually measure the mounting diameter and the mounting depth of the current speakers. This isn't too difficult to do and since you will probably want to install your new speakers yourself, the door panel will have to be removed anyway.

Be sure to lower your window inside the door and measure the available depth. Many times you will find newer replacement speakers will require a bit more depth then original equipment speakers.
