JL Audio provides excellent internal components in their subs, and the JL Audio C1-650 is no different. They work better as pairs and can offer 450 watts at peak for both or a 225 peak for a single sub. What really attracted our audio experts aside from the attention-grabbing yellow cone is the JL audio quality promise.

As we said, the brand always provides impressive construction, which is why the sound quality stands out. The sensitivity rating is an impressive 93 dB, with a frequency response range of 48 Hz all the way to 24,000!

• Incredible frequency response
• Relatively low impedance
• Great boost for factory vehicle speakers
• Durable subwoofers
• Highly sensitive

• Sound works better in pairs
• Low RMS and peak as a single sub

There is not much our audio team can say about the size, as we’re focusing on the top 6.5 subwoofers today. These subs can still provide a bass boost for your car audio to balance out the high frequency sounds. To do this, the sub must be in the correct ported or sealed enclosure and be made of durable materials.

To be a good match for your speaker system, the subwoofers should have large bumpers to add to the resilience, and must not be interfered by the magnetic field. Our expert audio team also recommends a rubber surround of possible, double-stitched butyl rubber to be exact, dual voice coils, and even dual drivers for bigger sound.

Our experts stress improved magnetic control within the sub will reduce distortion at various volume levels inside ported and sealed boxes. To ensure longevity and best value, make sure there are proper cooling channels to keep your subwoofer cool while the mounting bracket is sturdy.

The power rating of the sub will have an impact on your car audio. The power handling of a subwoofer feature is broken down into two categories – the RMS and the peak.

The RMS is the output the subwoofer can meet for long periods while the peak is the figure for short bursts. The peak is usually twice the amount of the RMS, and it’s the power rating that manufacturers usually advertise.

Our audio experts remind our readers that the RMS is the rating to pay attention to especially when looking forhigh-quality outdoor subs. It is the RMS that is how powerful your subwoofers will be to complement your speakers for everyday operation.

Speaker and subwoofer sensitivity and impedance mean the same thing. The impedance has a direct effect on the power consumption of your household sound equipment and car audio equipment.

The impedance a subwoofer features is measured in ohms, and it is indicative of the resistance your unit or sound system has to the electrical current flow. Ideally, our team says to look for a lower impedance. A lower impedance means your speakers or subs require less power to reach a certain output compared to ones that have a higher impedance.

The sensitivity is measured in decibels, or dB [1], and it has an impact on how loud your speaker and subwoofer is. To get a clear picture of how loud your bass can be, you need to look at the sensitivity and the power rating together.

Anywhere around 88 dB will deliver better than average speaker and subwoofer performance, but our experts have high standards and suggest at least 90 dB.

How easy is the setup of your new subs? Many subwoofers are component models, which means you will need to do the mounting on your own and find enclosures that match. The purpose of a very compact 6.5 sub is to accommodate limited space, so you need a shallow mount depth.

Depending on the type of speaker you have, such as coaxial speakers, you have to make sure the connections are compatible.
