Determine the most suitable type of car amplifier for your sound system.
There are models which are designed to boost the signal sent to two, four, five or even six speakers. You should choose the number of channels based on your current system or on your plans for expanding this system. If you plan to upgrade, you should definitely go for a model with more channels.
You should know that there are two types of channels. The stereo ones deliver either a left or right-side signal while the mono ones provide both left and right audio. If you have a subwoofer, you should certainly consider a car amplifier with two or more stereo channels and one mono channel which will give you the super deep bass that you want to enjoy.
Evaluate the power of the device extremely carefully.
The technical capabilities of the device are among the most important factors which you should base your choice on. There are two types of power measures to watch out for. The root mean square power or RMS power measures the amount of continuous power which the device delivers to the speakers. The RMS power of the amplifier must match that of the speakers.
The other measure is the peak amplifier power. It indicates how much wattage the device is able to use for short and unexpected increases in sound. This number is always higher than the RMS power number. The higher it is the better the device will perform so that you can enjoy even better sound quality.
Look for capabilities and features, which match your needs precisely.
Since your stereo system has a built-in amplifier, you have to choose the additional one in line with the capabilities of the original unit. Take into account the amplifying power of the built-in unit and ensure that the additional one provides between 75% and 150% of the power limit of the speakers.
If you want to get super deep bass, you should go for a device with low-pass filter and built-in bass boost. That way, you will literally feel your heart pounding with the beat of the music. If you want trebles with amazing clarity coming out of your tweeter speakers, you should go for a device which features a high-pass filter. That way, you will protect the speakers and ensure that they will have a long useful life in addition to enjoying music even more.
Get all the accessories which you need for installing the device.
Most amplifiers designed to be used in cars do not come with all accessories which are necessary for their installation. That is why you should check what is included in the package and get the rest of the items separately. Alternatively, you can consider purchasing a complete car-wiring kit.
Finally, you should certainly consider buying a car amplifier from a brand, which has solid market performance and excellent reputation. That way, you will not have to worry about quality. Besides, you will get a warranty which is comprehensive and sufficiently long.
