How to Choose The Best Car Amplifier for Your Vehicle

After working with car stereo shoppers for a long time, there isn’t any doubt that many have difficulty with deciding on the top power amplifier for their audio system.

By using these basic steps for selecting the Best Car Amplifier, the consumer can cut through all the nonsense and miss-information which tends to float around the retail mobile entertainment industry.

Though there are several top quality power Car Amplifiers available, I’ve found a great many will certainly select a Rockford Fosgate, Hifonics or Kicker amp due to their good reputation, their power and value.


The initial step one should take is to decide on or get subs or speakers. This strategy can work well considering that your speakers or sub woofer selection could possibly be effected by certain size and space limits.

This is also a very good initial step since it means that you can have the speaker specifications available prior to searching for an amplifier. Check the spec sheet and see the amount of power is proposed to get top rated efficiency from your speakers.

The second step may be to consider where you’ll install your amp. You’ll want to select a place which will let you mount your amp securely and allowing for adequate air circulation.

All sizes of power amplifiers will produce heat which means this may present a challenge. In standard autos a car trunk is normally the most suitable location while in pickups or SUV’s you might have to pick an area beneath a seat. Your install area will determine the optimum size amp you can consider.

Your third step can be to figure out how you will wire your speakers or subwoofer because that could limit your search down due to the any amplifier’s configuration.

There are numerous two channel or 4 channel amps that could power either pairs of speakers or a sub woofer. Though most often, your best option for just a subwoofer set up would be a good class-D amplifier.

When contemplating the power, an effective rule to follow is to power an amplifier at 80% to 90% of whatever they are designed for. Always use the RMS or continuous power rating for comparison and never the peak power.

This will likely deliver top quality sound out of your car speakers along with a good extended life from any amp. You should check any amplifier’s output capability at 4 ohms simply because generally in most installs, you will end up building a four ohm setup.

When you’re only adding a subwoofer, then look at your subwoofer to determine what’s the lowest ohm setup attainable after which match a mono amp to that level.

Again, when looking at an amplifier’s potential, look at the specific output at RMS or continuous power ratings and do not worry about maximum power.

It has become an industry wide a style of advertising to pay attention to max power allowing retailers to market many amps as being more powerful then they are really. Checking the continuous power provides a much better reflection of how an amp is going to be used.

For the majority of installations, it is wise to power one set of speakers using a stereo-amp and 2 sets of full-range speakers by using a 4 channel amp. This provides you with much better control when setting up your amp. If introducing a subwoofer to this system, you may very easily add a mono class-D amplifier.

Needless to say there are various ways to wire speakers and amplifiers but this straight forward method is without doubt the most popular and as a rule will give the very best results.
