Car Amplifier Warranty

Regardless how great of a model or power output of the amplifier, it will be worthless if it breaks down in a few weeks and you have to spend that money again. The best thing that you can do before choosing any amplifier is inquire about the warranty. Here is something to carefully consider, most of the amp manufacturers won’t honor the warranty that you think is valid unless you made the purchase from an authorized retailer. Although this doesn’t seem fair, the reasoning behind this is the manufacturer has spent considerable time and money setting up those distribution chains, and they trust those they work with. If the product was sold by an authorized distributor, the company can follow the car amplifier by serial number every step of the way since it left their factory.

When you buy a car amplifier from an unauthorized dealer, the manufacturer has no way of telling where it has been and what could have been done to it. To ensure you are getting a valid amp warranty, verify the seller is an authorized dealer by calling the company to make sure they are on the list. If you buy the amp and get a warranty from an unauthorized dealer, buyers beware.

Value For Money

It might be tempting for you to spend $200 on that 2000 watt car amplifier, but step back and do a little analysis here of the numbers. Check the voltage of your vehicle, the average for most vehicles is about 13.5 volts. Now consider the draw, or fuse rating of the amplifier you are considering to buy, they average 0.6 for a Class AB car amplifier and 0.8 for the Class D amplifiers. For sake of this example, if your amplifier is fused at 50 amps and you are going with the Class AB, then 50 (amps) X 13.5 (volts) X 0.6 (rating) will equal only 405 watts. That means 405 watts is the most AB amp fused at 50 amps can produce. Knowing the math, look for a car amplifier that advertises their exact rating, then check the fuse and do the math yourself to make certain you are getting the most bang for your buck.

Physical Size Of The Car Amplifier

It doesn’t matter how many features or how powerful the car amplifier you are considering has, if it doesn’t fit in your vehicle, it isn’t going to work. Take exact measurements of the space that you have in the vehicle set aside for the amp, because that huge car amplifier you have your eyes on will never fit under the car seat no matter how hard you try. Like we said earlier, technology is evolving at record speeds in the area of car amps, and the same power output of an amp from three years ago could be three times smaller in size. Don’t assume a small amp means small power, these little devices can compete with the biggest and baddest of them. The car amplifiers being produced today are tiny, but so are vehicles in which these amplifiers are fitted. Take exact measurements of the space in the dash or under the seat, and then shop with that space in mind. The newer car amp model you choose, the smaller the physical size without compromising any of the sound.


Never assume that the wiring is the amp kit is going to serve your needs, you simply need to do your homework and make certain you are getting what you paid for. When it comes to amp wire kits, the best you can find are oxygen-free copper. Although the price of cooper is skyrocketing and so is the cost of the wires, in this case you get what you paid for. These wires will help produce superior sound and last longer than copper clad aluminum wire kits. The copper is a far better conductor of electricity then the aluminum. If you put it in clear terms, an 8 gauge OFC wire kit carries more current than a 4 gauge CCA wiring kit.

One other thing to consider when it comes to the wiring of the car amplifier, the size of the wires in the kit. A decade ago, a 4 gauge wire was truly a 4 gauge wire. Today, with imports of these kits, quality is being compromised, and thicket coating and little wire are being sold as 4 gauge. Beware of Chinese manufactured wiring kits, check reviews before making the purchase, and consider OFC wire kits.

Car Amplifier Compatibility

Don’t assume that the car amplifier that you have your eyes on will be compatible with the ohm load that it will be wired to. If you are not taking the steps to ensure that they are a perfect match and you overload the car amp, the manufacturer will not honor the warranty in most cases. There are some people who hastily bought a one channel amplifier for a four channel application and watched the unit fry right before their eyes. If you have questions or concerns, ask the seller or reach out to the manufacturer help desk. Many have live chat on their websites in addition to around the clock technical support.


If you are connecting the car amplifier to a factory deck, then you need to make sure the amplifier has high level inputs that will work with that direct connection. If you have a sub-woofer, you need to make sure the amplifier has high level inputs that will work with that direct connection. If you have a sub-woofer, you need to make sure the amplifier has a subsonic filter. You also need to make certain that the amplifier will be stable when connected to your desired ohm load.

As you can see, your specific needs must align with the specs of the amplifier to get the desired sound. Talk to a local professional shop, they do these installations all the time and will be in the best position to tell you what you need and what to avoid when selecting the right car amp.

Choosing a More Powerful Car Amplifier

You might think It is counterproductive to buy a more powerful car amplifier than you will need, but there is a good reason to beef up on this aspect of the purchase. Car speakers rarely get blown-out from too much power, in fact, blown speakers are a result of the amp having too little power. So you buy that 2000 watt amp we  talked about earlier, it produces 405 watts, so you crank up the gain control and increase the clippings and fry the speakers. That amp didn’t have enough power, so by artificially ramping it up, you blew the speakers.

Buy a little more power than you really need with a car amp and the gains can stay at the appropriate settings. The result, better sound and less chance of your speakers being blown out.

Now that we have discussed the steps for choosing a car amplifier, it is time to select one from the thousands available for sale. There are good amps, there are bad amps, and the following list of the most popular car amps will at least have you headed in the right direction.
