What You Need To Know When Buying the Best 4 Inch Speakers
When upgrading your car stereo, you’ll need to replace the stock speakers. 4-inch replacement speakers are a perfect size for replacing stock speakers in almost all cars. Their compact size makes them easy to fit in most cars. As you can see in the above review, different 4-inch speakers may come with different features. Thus, you need to know certain things when choosing the best 4 inch speakers. Here’s is what you need to know when making your final decision:
Certain materials are always better than others when it comes to making speakers. Thus, ensure the speaker you’re choosing is made of high-quality materials. Top-quality materials will guarantee you longevity of the speaker. Most importantly, ensure the speaker cone and surround are made of durable materials to ensure the speaker doesn’t tear easily. The speaker materials should be able to withstand prolonged usage. The speaker design should also integrate latest technologies for enhanced sound reproduction.
Speaker Power Rating
The power rating of the speakers you’ll choose for your car stereo will largely determine how powerful they’ll sound. If you want more powerful speakers, then go for speakers with a higher RMS power rating. Speakers with higher RMS rating will demand more power from your head unit, but they will surely reproduce deeper sound. If their power rating is higher, you’ll also need a powerful head unit or else invest in an external amp. If you want to stick to your stock head unit, then you may have to invest in less powerful speakers.
The sensitivity of the speakers you’ll choose will determine its compatibility with different head units. For instance, a speaker with a high sensitivity rating doesn’t demand a lot of power from the receiver. Thus, it can be easily powered by a stock head unit. On the contrary, if the speaker has a high sensitivity rating, then it’ll need more power and this means powering it with a powerful aftermarket receiver or an external car amp.
You’ll need to consider whether the speaker comes with mounting hardware such as mounting screws, adapter rings, and speaker wire. Replacement speakers that come with mounting hardware make it easier and hassle-free to install. For instance, if a replacement speaker comes with a mounting adapter ring or plate, it’ll be easier to install it in most speaker holes without having to cut out new speaker holes. It’ll also help when the speaker comes with all mounting hardware rather than having to buy them separately.
When choosing replacement speakers for your car audio system, always go for the highest quality speaker within your budget. However, your budget should not be the main determining factor. The main determining factor should be a speaker that has all the key features you need. With this review on the best 4 inch speakers in mind, you’ll rest assured of finding a replacement speaker that has everything you need. Moreover, we have reviewed speakers in a wide price range. Thus, there’s a speaker here ideal for everyone.
