  • Output Power: 80 watts
  • RMS Power: 40 watts
  • Impedance: 4-Ohm

The Rockford Fosgate R1525X2 is a coaxial 5.25-inch speaker that has everything built-in to eliminate the need for the external tweeter, woofers, and crossovers, which makes it our best overall. Besides being complete, it will deliver a high-quality sound with minimal distortion thanks to the integrated tweeter crossover.

Instead of foam, this speaker uses a high-quality rubber surround that will be more durable. With the provided grille and the silk dome flush mounted tweeter, the speaker will look as good as it sounds.

Apart from providing the grille, the manufacturer also provides the mounting hardware, which will ensure you have everything you need to mount and start using it immediately.

The bass seems to be a little lacking and is more dependent on the amp that you have. But the good news is that with a good amp or subwoofer, these speakers can still deliver quite a powerful bass. While some motorists might not like having to drill their doors to install this speaker, if done correctly, this should not be a big issue.

Pros

  • Speaker is complete with tweeter and woofer
  • Integrated tweeter crossover for better sound quality
  • Highly durable rubber surround
  • Flush mounted tweeter creates a cleaner look
  • Comes with the mounting hardware

Because the two speakers will include the FlexFit basket design, you can quickly line them up when mounting to ensure you get a perfect fit. To ensure you can mount and use them immediately, they will also come with the mounting hardware, grills, and OEM adapter plates.

The bass is still not strong enough or at least not as good as what you get with other larger vehicle speakers. However, for 5.25-inch speakers, it is almost as good as it can get. What's more, a good amp should help make it a little more robust. And the extra weight should not be a concern as it is an indication that these are well-built speakers.

How to Buy the Best 5.25-Inch Car Speaker

How To Buy The Best 5.25-Inch Car Speakers

1. Component or Coaxial

As you shop for the best 5.25-inch car speakers, you will often come across two main types, which are component and coaxial. Hence, your first decision will be to pick between these two, as each will be ideal for different situations.

Component

Component speakers or separates, as they are also fondly referred to as, are famous for delivering an impressive sound reproduction. They are small speakers that will get their name from the fact that they separate the different sound frequencies.

These speakers need to paring with crossovers, subwoofers, and tweeters. Component speakers will give out high-quality audio as they are more efficient at sound imaging and will produce relatively more bass from the woofer.

The component speakers like the Infinity Kappa 50.11CS are ideal for those that are looking for a more custom sound system setup. However, the component speakers tend to be more expensive when compared to the coaxial types.

Coaxial

Coaxial speakers like Polk Audio DB522 are also known as the full-range speakers, and they tend to be more affordable when compared to the component speakers. But unlike component speakers, all the elements will be combined into the speaker.

These speakers typically have the crossovers built-in, and a tweeter mounted on the woofer cone. Coaxial speakers are what you are likely to get with most factory vehicle audio systems.

Although these speakers can still handle all sound frequencies, there is a high possibility of interference given that drivers tend to be very close. They are also less customizable when compared to component speakers.

Buying Advice: If you prefer a speaker system that will allow for greater customization, and generally deliver superior sound quality and do not mind spending more cash, go for the component types. However, if you are shopping on a small budget and also want a speaker that does not require external tweeters, crossovers, or woofer, the coaxial types are your best pick.

2. Power Handling

The maximum power handling capability of a speaker is always among the most crucial elements to consider when choosing one as it will determine how much power it can tolerate before it blows out.

Besides the maximum power handling, you will also need to pay attention to the RMS, which is the ultimate power the speaker can handle continuously. For the best quality and full-range sound, it is a great idea to keep the RMS and peak power close, such as 100 and 200 watts, respectively, for example.

That said, a peak power of between 80 and 300 watts should be good enough for 5.25-inch speakers. For the RMS, on the other hand, 40 to 100 watts should be enough for these speakers.

3. Configuration

Speaker configuration also matters when it comes to choosing a 5.25-inch speaker, and here the most common options are the 2-way, 3-way, and 4-way speakers.

2-way speakers will provide excellent all-round performance while 3-way speakers will be perfect for midrange, and 4-way will give you superior performance in the highs.

4. Build Material

While the 5.25-inch speakers might generally be more affordable, you still need something that gives you value for money by serving you long enough. One of the main ways to ensure this is by choosing one that is well-built using high-quality materials.

You need to check both the woofer frame and cone materials and other things like the magnet used. There is a wide variety of materials used for these different elements.

For example, the cone can be made from synthetic fibers with metals coatings if it is a high-end model or polypropylene for the cheaper ones. All in all, the most important thing is to ensure the materials are tough enough for the speaker to serve you well for long.
