If you’re looking for the best, the Rockford Fosgate has the answer. They don’t have the elite level of quality you see in the most expensive models, but in terms of value for money, there is going to be nothing better.

The only downside that we see here is that it doesn’t have the very highest level of quality at the low-frequency level. Also, the materials that are used aren’t of the highest quality either. But that helps to keep that brilliant price down.

We’ve talked about the low frequencies, but in the mid to high range, you’re not going to have any complaints. The sound you get is exceptional and is a significant upgrade on almost all factory speakers, which is what you want to see.

A one-year warranty backs the solid construction of these speakers, and it’s clear that they are very well made. You get the grilles included to get a higher level of protection than you get with budget speakers.

The sound quality of these JBL speakers is excellent, and they’ll allow you to transform the way that you listen to music in your car. You’ll see a huge difference between these and the default factory speakers you have installed.

One aspect that slightly lets these down are the plastic mounting tabs. You just have to be careful when you’re installing them. Some modifications may be required to the mount, but for most people, they are going to fit easily.

The low level of impedance and the frequency separation shows the high level of technology that is behind these speakers. Added to those qualities is an adjustable tweeter to get the sound in the exact place you want it.

JVC is usually a brand you can trust, but does that extend to these speakers? Absolutely. They have been around for a while now and remain intensely popular. We thought they were brilliant, and the user reviews we see here back that up.

That being said, there are a few cons. Similar to the JBL model we’ve just looked at, these 6.5″ speakers don’t have the highest quality brackets available. To get the most out of these speakers, you probably also need an amp to go with them.

You’d be forgiven for thinking that these speakers come at a hefty price tag, but in fact, they are one of the cheapest models out there. They represent excellent value for money but don’t quite have that elite level of build quality or performance.

The design is stylish which will improve the look of your car and also the mounts on them are quite shallow, which makes them easier to install and gives them a universal fit.

While they are easy to install for almost all users, they do have quite a short wiring connector which is something for you to bear in mind. While that may be a problem for some, they do have a shallow mount that is going to delight others.
